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 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 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).

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.
