Precision, Low-Voltage Analog Switches
_______________General Description ____________________________Features
The MAX381/MAX383/MAX385 are precision, low-volt-
age analog switches. The single-pole single-throw
MAX381 and double-pole single-throw MAX385 dual
switches are normally open. The single-pole double-
throw 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 leak-
age (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 Single-Supply Operation (+3V to +15V)
Bipolar-Supply Operation (±3V to ±8V)
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
The MAX381/MAX383/MAX385 are fabricated with
Maxim’s low-voltage silicon-gate process for high sys-
tem accuracy. Design improvements guarantee
extremely low charge injection (<5pC) and low power
consumption (<10µW).
o TTL/CMOS-Logic Compatible with 3V, 5V, ±3V,
and ±5V Supplies
o Rail-to-Rail Analog Signal Handling Capability
______________Ordering Information
These monolithic switches operate with a single posi-
tive 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.
