ADG419BNZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG419BNZ is a monolithic CMOS single-pole double-throw (SPDT) analog switch fabricated on an enhanced LC2MOS process. It operates with dual supplies ranging from ±5 V to ±16.5 V or a single supply of 5 V to 13.2 V. The device features a maximum on-resistance of 35 Ω and ultralow power dissipation below 35 μW. Transition times are limited to 160 ns, while off-leakage currents remain under 15 nA at maximum ratings. It provides an analog signal range extending to the supply rails within an 8-pin PDIP package.
