Maxim MAX381/MAX383/MAX385 Precision Low-Voltage Analog Switches Datasheet
The MAX381, MAX383, and MAX385 are precision low‑voltage analog switches offered by Maxim. They are single‑pole single‑throw (MAX381), double‑pole single‑throw (MAX385), and single‑pole double‑throw (MAX383) devices with low on‑resistance and low leakage.
These switches support single‑supply operation from +3 V to +15 V or bipolar supplies from ±3 V to ±8 V, provide fast switching (<175 ns turn‑on, <100 ns turn‑off), and consume less than 10 µW, making them suitable for sample‑and‑hold circuits, military radios, test equipment, and other applications.
