Precision, Low-Voltage Analog Switches
____________________________Features
o Single-Supply Operation (+3V to +15V)
Bipolar-Supply Operation (±3V to ±8V)
The MAX381/MAX383/MAX385 are precision, low-voltage analog switches. The single-pole single-throw
MAX381 and double-pole single-throw MAX385 dual
switches are normally open. The single-pole doublethrow MAX383 has two normally open and two normally
closed poles. All three parts offer low on-resistance
(less than 35Ω), guaranteed to match to within 2Ω
between channels and to remain flat over the specified
analog signal range (4Ω max). They also offer low leakage (less than 250pA at +25°C and less than 2.5nA at
+85°C) and fast switching (turn-on time less than 175ns
and turn-off time less than 100ns).
o Pin-Compatible with DG401/DG403/DG405
o Low On-Resistance, 20Ω Typical (35Ω Max)
o Guaranteed Matched On-Resistance Between
Channels, <2Ω
o Guaranteed Flat On-Resistance over Specified
Analog Signal Range, <4Ω
o Guaranteed Charge Injection, <5pC
o Guaranteed Off-Channel Leakage, <2.5nA at +85°C
o TTL/CMOS-Logic Compatible with 3V, 5V, ±3V,
and ±5V Supplies
o Rail-to-Rail Analog Signal Handling Capability
The MAX381/MAX383/MAX385 are fabricated with
Maxim’s low-voltage silicon-gate process for high system accuracy. Design improvements guarantee
extremely low charge injection (<5pC) and low power
consumption (<10µW).
These monolithic switches operate with a single positive supply (+3V to +15V) or with split supplies (±3V to
±8V) while retaining CMOS-logic input compatibility
and fast switching. CMOS inputs provide reduced input
loading.
