Low-Voltage, Dual Supply, SPST, High Performance Analog Switches

The Intersil ISL43112 and ISL43113 are precision, high performance analog switches designed to operate from ±1.5V to ±6V supplies. These devices are fully specified for 10 tolerance ±5V and ±3.3V supplies, and feature supply and leakage currents much lower than those of other single SPST switches. Turn-on and turn-off times are also improved.
