DG302AAK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG302AAK/883B is a dual-channel, single-pole double-throw (SPST-NO) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It utilizes CMOS technology and is housed in a 14-pin ceramic dual in-line package (CDIP). The device supports a dual supply voltage of ±15V and operates within an extended temperature range of -55°C to +125°C. Key electrical specifications include a maximum on-resistance of 50 Ohms, a charge injection of 8 pC, and an off-state leakage current of 1 nA. Switching times are specified at a maximum of 300 ns for turn-on and 250 ns for turn-off.
