PS381/PS383/PS385
Precision, 17V Analog Switches
Description
Features
• Low On-Resistance (16Ω typ) Minimizes Distortion
and Error Voltages
• Low Glitching Reduces Step Errors in Sample-and-Holds.
Charge Injection, 3pC typ
The PS381/PS383/PS385 are improved high precision, medium
voltage analog switches designed to operate with +3V to +8V
power supplies.
The PS381 has two normally open (NO) switches. The PS383 is a
dual, single-pole double-throw (SPDT) switch. The PS385 is a
dual, double-pole single-throw (DPST) function. Each switch
conductscurrentequallywellineitherdirectionwhenon. Intheoff
state each switch blocks voltages up to the power-supply rails.
• Single Supply (+3V to +15V) or Split-Supply
(+3V to +8V) Operation
• Improved Second Sources for MAX381/MAX383/MAX385
• On-Resistance Matching Between Channels, 0.2 Ω typ
• On-Resistance Flatness, 1Ω typ
o
With ±5V power supplies, the PS381/PS383/PS385 guarantee
<30Ω on-resistance. On-resistance matching between channels is
within2Ω. On-resistanceflatnessislessthan4Ωoverthespecified
range. All three devices feature low leakage currents (<2 pA @
• Low Off-Channel Leakage, <2.5nA @ +85 C
• TTL/CMOS Logic Compatible
• Rail-to-Rail Analog Signal Dynamic Range
• Low Power Consumption <1µA

Break-before-make switching action protects against momentary
crosstalk (PS383).
Applications
• Instrumentation, ATE
• Sample-and-Holds
• Audio Switching and Routing
• Telecommunication Systems
• PBX, PABX
These switches are fully specified for single +5V operation,
with <45Ω R , <2Ω R match, and <4Ω R flatness.

Notes:
1. The algebraic convention, where the most negative value is a minimum and the most positive is a maximum, is used in
this data sheet.
2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.
3. Guaranteed by design
4. ∆RΟΝ = ∆RΟΝ max - ∆RΟΝ min
5. Flatness is defined as the difference between the maximum and minimum value of on-resistance measured.
6. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25ºC.
7. Off Isolation = 20log10 [ VCOM / (VNO or VNO) ]. See figure 5.
8. Between any two switches. See figure 6.
