ISL43113: Low-Voltage, Dual Supply, SPST, High Performance Analog Switch

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.

Targeted applications include battery powered equipment that benefit from the devices’ low power consumption (250μW), sub-nanoamp leakage currents and fast switching speeds (tON = 40ns, tOFF = 25ns). The small SOT-23 packages and timing that delivers break-before-make operation, make this family ideal for custom multiplexer applications. Additionally, excellent rON flatness maintains signal fidelity over the whole input range, while micro packaging alleviates board space limitations. All these benefits combine to make Intersil’s newest line of low-voltage switches ideal solutions for “Next Generation” designs.

The ISL4311x are Single-Pole/Single-Throw (SPST) switches, with the ISL43112 being Normally Open (NO) and the ISL43113 being Normally Closed (NC).
