DG303AEWE+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303AEWE+ is a TTL-compatible CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two single-pole double-throw (SPDT) channels housed in a 16-SOIC package. The device operates with dual power supplies ranging from ±5V to ±18V or a single supply of 10V to 30V. Key electrical specifications include a maximum on-resistance of 50 Ohms, a maximum charge injection of 12pC, and an off-state leakage current of 1nA. Switching times are specified at a maximum of 300ns for turn-on and 250ns for turn-off. The component supports a DC switch current of 30mA and offers a crosstalk rejection of -74dB at 500kHz.
