Product Summary

The ISL431 is a precision, high performance analog switch. The ISL431 is fully specified for 3.3V, 5V, and 12V operation, and feature improved leakage, Icc, and switching time specifications. Designed to operate from a single +2.4V to +12V supply, the low supply current (1μA Max over the temperature and voltage ranges) and low leakage currents (1nA) make the switch ideal for battery powered applications. The applications of the ISL431 include +3V/+5V DACs and ADCs, Sample and Hold Circuits, Digital Filters, Operational Amplifier Gain Switching Networks, High Frequency Analog Switching, High Speed Multiplexing, Integrator Reset Circuits.
