•
低导通电容
MUX508 和 MUX509 (MUX50x) 是现代互补金属氧化
物半导体 (CMOS) 模拟多路复用器 (mux)。MUX508
提供 8:1 单端通道,而 MUX509 提供 4:1 差分通道或
双 4:1 单端通道. MUX508 和 MUX509 在双电源(±
5V 至 ±18V)或单电源(10V 至 36V)供电时均能正
常运行。两种器件在由对称电源(如 VDD = 12V,VSS
= –12V)和非对称电源(如 VDD = 12V,VSS = –5V)
供电时也能保证优异性能。所有数字输入具有兼容晶体
管-晶体管逻辑电路 (TTL) 的阈值。当器件在有效电源
电压范围内运行时,该阈值可确保 TTL 和 CMOS 逻辑
电路的兼容性。

8.2 On-Resistance
The on-resistance of the MUX50x is the ohmic resistance across the source (Sx, SxA, or SxB) and drain (D, DA,
or DB) pins of the device. The on-resistance varies with input voltage and supply voltage. The symbol RON is
used to denote on-resistance. The measurement setup used to measure RON is shown in Figure 26. Voltage (V)
and current (ICH) are measured using this setup, and RON is computed as shown in Equation 1.

8.3 Off-Leakage Current
There are two types of leakage currents associated with a switch during the off state:
1. Source off-leakage current
2. Drain off-leakage current
Source off-leakage current is defined as the leakage current flowing into or out of the source pin when the switch
is off. This current is denoted by the symbol IS(OFF)
.
Drain off-leakage current is defined as the leakage current flowing into or out of the drain pin when the switch is
off. This current is denoted by the symbol ID(OFF)
.
The setup used to measure both types of off-leakage currents is shown in Figure 27.

8.6 Break-Before-Make Delay
Break-before-make delay is a safety feature that prevents two inputs from connecting when the MUX50x is
switching. The MUX50x output first breaks from the on-state switch before making the connection with the next
on-state switch. The time delay between the break and the make is known as a break-before-make delay.

8.7 Turn-On and Turn-Off Time
Turn-on time is defined as the time taken by the output of the MUX50x to rise to a 90% final value after the
enable signal has risen to a 50% final value. Figure 31 shows the setup used to measure turn-on time. Turn-on
time is denoted by the symbol tON
.
Turn-off time is defined as the time taken by the output of the MUX50x to fall to a 10% initial value after the
enable signal has fallen to a 50% initial value. Figure 31 shows the setup used to measure turn-off time. Turn-off
time is denoted by the symbol tOFF

8.8 Charge Injection
The MUX50x have a simple transmission-gate topology. Any mismatch in capacitance between the NMOS and
PMOS transistors results in a charge injected into the drain or source during the falling or rising edge of the gate
signal. The amount of charge injected into the source or drain of the device is known as charge injection, and is
denoted by the symbol QINJ. Figure 32 shows the setup used to measure charge injection.

Bandwidth is defined as the range of frequencies that are attenuated by < 3 dB when the input is applied to the
source pin of an on-channel and the output is measured at the drain pin of the MUX50x. Figure 35 shows the
setup used to measure bandwidth of the mux. Use Equation 4 to compute the attenuation.

8.12 THD + Noise
The total harmonic distortion (THD) of a signal is defined as the ratio of the sum of the powers of all harmonic
components to the power of the fundamental frequency at the mux output. The on-resistance of the MUX50x
varies with the amplitude of the input signal and results in distortion when the drain pin is connected to a low-
impedance load. Total harmonic distortion plus noise is denoted as THD+N. Figure 36 shows the setup used to
measure the THD+N of the MUX50x.

9.3 Feature Description
9.3.1 Ultralow Leakage Current
The MUX50x provide extremely low on- and off-leakage currents. The MUX50x are capable of switching signals
from high source-impedance inputs into a high input-impedance op amp with minimal offset error because of
these ultralow leakage currents. Figure 37 shows typical leakage currents of the MUX50x versus temperature.

9.4 Device Functional Modes
When the EN pin of the MUX50x is pulled high, one of the switches is closed based on the state of the address
lines. When the EN pin is pulled low, all the switches are in an open state irrespective of the state of the address
lines. The EN pin can be connected to VDD (as high as 36 V).

10 Applications and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
10.1 Application Information
The MUX50x family offers outstanding input/output leakage currents and ultralow charge injection. These devices
operate up to 36 V, and offer true rail-to-rail input and output. The on-capacitance of the MUX50x is very low.
These features makes the MUX50x a precision, robust, high-performance analog multiplexer for high-voltage,
industrial applications.
10.2 Typical Application
Figure 42 shows a 16-bit, differential, four-channel, multiplexed, data-acquisition system. This example is typical
in industrial applications that require low distortion and a high-voltage differential input. The circuit uses the
ADS8864, a 16-bit, 400-kSPS successive-approximation-resistor (SAR) analog-to-digital converter (ADC), along
with a precision, high-voltage, signal-conditioning front end, and a four-channel differential mux. This application
example details the process for optimizing a precision, high-voltage, front-end drive circuit using the MUX509,
OPA192 and OPA140 to achieve excellent dynamic performance and linearity with the ADS8864.

lowest distortion using the 16-bit ADS8864 at a throughput of 400 kSPS for a 10-kHz, full-scale, pure, sine-wave
input. The design requirements for this block design are:
•
•
•
•
•
System supply voltage: ±15 V
ADC supply voltage: 3.3 V
ADC sampling rate: 400 kSPS
ADC reference voltage (REFP): 4.096 V
System input signal: A high-voltage differential input signal with a peak amplitude of 20 V and frequency
(fIN) of 10 kHz are applied to each differential input of the mux.

Typical Application (continued)
10.2.2 Detailed Design Procedure
The purpose of this precision design is to design an optimal, high-voltage, multiplexed, data-acquisition system
for highest system linearity and fast settling. The overall system block diagram is illustrated in Figure 42. The
circuit is a multichannel, data-acquisition signal chain consisting of an input low-pass filter, mux, mux output
buffer, attenuating SAR ADC driver, and the reference driver. The architecture allows fast sampling of multiple
channels using a single ADC, providing a low-cost solution. This design systematically approaches each analog
circuit block to achieve a 16-bit settling for a full-scale input stage voltage and linearity for a 10-kHz sinusoidal
input signal at each input channel.
For step-by-step design procedure, circuit schematics, bill of materials, PCB files, simulation results, and test
results, see TI Precision Design TIPD151, 16-Bit, 400-kSPS, 4-Channel Multiplexed Data-Acquisition System

11 Power-Supply Recommendations
The MUX50x operates across a wide supply range of ±5 V to ±18 V (10 V to 36 V in single-supply mode). The
MUX508 and MUX509 operate equally well with either dual supplies (±5 V to ±18 V), or a single supply (10 V to
36 V). They also perform well with unsymmetric supplies such as VDD = 12 V and VSS = –5 V. For reliable
operation, use a supply decoupling capacitor with a capacitance between 0.1 µF to 10 µF at both the VDD and
VSS pins to ground.
The on-resistance of the MUX50x varies with supply voltage, as shown in Figure 44.

12 Layout
12.1 Layout Guidelines
Figure 45 shows an example of a PCB layout with the MUX508IPW, and Figure 46 shows an example of a PCB
layout with MUX509IPW. The guidelines provided in this section are also applicable to the SOIC MUX508ID and
MUX509ID package variants as well.
Some key considerations are:
1. Decouple the VDD and VSS pins with a 0.1-µF capacitor, placed as close to the pin as possible. Make sure
that the capacitor voltage rating is sufficient for the VDD and VSS supplies.
2. Keep the input lines as small as possible. For the MUX509 differential signals, make sure the A inputs and B
inputs are as symmetric as possible.
3. Use a solid ground plane to help distribute heat and reduce electromagnetic interference (EMI) noise pickup.
4. Do not run sensitive analog traces in parallel with digital traces. Avoid crossing digital and analog traces if
possible and only make perpendicular crossings when necessary.
