Low-Voltage, Dual DPDT/Quad SPDT
Analog Switches in QFN
691/MAX4702
General Description
Features
The MAX4699/MAX4701/MAX4702 are low-voltage,
single-supply CMOS analog switches. The MAX4699/
MAX4701 are dual double-pole/double-throw (DPDT)
switches with two control inputs that control two
single-pole/double-throw (SPDT) switches each. The
MAX4702 is a quad SPDT switch with one control input
and one low-voltage digital logic power supply.
♦ 3mm x 3mm and 4mm x 4mm 16-Pin TQFN
Packages
♦ Guaranteed On-Resistance:
75Ω (max) (+3V Supply)
40Ω (max) (+5V Supply)
♦ Guaranteed Match Between Channels:
4Ω max
These devices operate from a single +1.8V to +5.5V
power supply. When powered from a +2.7V supply the
MAX4699/MAX4701/MAX4702 offer a 75Ω on-resis-
♦ Guaranteed Flatness Over Signal Range:

flatness and 4Ω max
♦ Low Leakage Currents Over Temperature:

matching between channels. Each switch has rail-to-rail
signal handling, fast switching speeds of t = 35ns,
1nA Max at +85°C
ON
♦ Fast Switching: t
= 35ns, t
= 20ns

t
= 20ns, and a maximum 1nA of leakage current.

♦ Guaranteed Break-Before-Make
The MAX4699/MAX4701 digital inputs are 1.8V-logic
compatible when operated from a +3V supply. The
MAX4702’s digital inputs feature a 1.0V threshold when
powered with a 1.5V logic supply.
♦ Single-Supply Operation from +1.8V to +5.5V
♦ Rail-to-Rail Signal Handling
♦ -3dB Bandwidth: 250MHz
♦ Low Crosstalk: -79dB (1MHz)
♦ High Off-Isolation: -76dB (1MHz)
The MAX4699 is available in a space-saving 16-lead
4mm x 4mm TQFN package. The MAX4701/MAX4702
are available in space-saving 16-lead 3mm x 3mm TQFN
16-pin TSSOP packages.

Note 1: Signals on IN_, COM_, NO_, and NC_ exceeding 0 or V+ are clamped by internal diodes. Limit forward-diode current to
maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Detailed Description
POSITIVE SUPPLY
The MAX4699/MAX4701 are low-voltage CMOS analog
switches that operate from a single +1.8V to +5.5V
power supply. The MAX4702 requires an additional
logic supply that allows for setting lower logic thresh-
olds. The MAX4699/MAX4701 are double-pole/double-
throw (DPDT) devices. The MAX4702 is a quad
single-pole/double-throw (SPDT) device. These devices
feature a break-before-make switching, fast switching

Applications Information
Figure 1. Overvoltage Protection Using Two External Blocking
Diodes
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) can be passed with very little change in on-
resistance (see Typical Operating Characteristics). The
switches are bidirectional, so the NO, NC, and COM pins
can be used as either inputs or outputs.

Analog Switches in QFN
Adding protection diode D2 causes the logic threshold
to be shifted relative to GND. TTL compatibility is not
guaranteed when D2 is added.
Power-Supply Sequencing and
Overvoltage Protection
Caution: Do not exceed the absolute maximum rat-
ings because stresses beyond the listed ratings
may cause permanent damage to the devices.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V+ before applying
analog signals, especially if the analog signal is not cur-
rent limited. If this sequencing is not possible, and if the
analog inputs are not current limited to <20mA, add a
small-signal diode (D1) as shown in Figure 1. If the ana-
log signal can dip below GND, add D2. Adding protec-
tion diodes reduces the analog range to a diode drop
(about 0.7V) below V+ (for D1), and a diode drop above
ground (for D2). On-resistance increases slightly at low
supply voltages. Maximum supply voltage (V+) must not
exceed +6V.
Protection diodes D1 and D2 also protect against some
overvoltage situations. With Figure 1’s circuit, if the sup-
ply voltage is below the absolute maximum rating, and
if a fault voltage up to the absolute maximum rating is
applied to an analog signal pin, no damage will result.
V Logic Input (MAX4702)

The MAX4702 features a V logic input that allows for
L
lower logic input thresholds down to 1.0V min for V in
the quad SPDT configuration. Power-up V after V+ has
IH
L
been powered with a minimum of 1.5V to ensure proper
operation of the device.

MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT IC TERMINALS.
OFF-ISOLATION IS MEASURED BETWEEN COM_ AND "OFF" NO_ OR NC_ TERMINAL ON EACH SWITCH.
ON-LOSS IS MEASURED BETWEEN COM_ AND "ON" NO_ OR NC_TERMINAL ON EACH SWITCH.
CROSSTALK IS MEASURED FROM ONE CHANNEL TO ALL OTHER CHANNELS.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
