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 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). 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). 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.
