Product details

SPDT analog switch for precision signal routing

It routes one of two analog or digital signals to a common output, controlled by a logic-level select pin. The part is built for precision applications that need low on-resistance (35 ohm max), fast switching (175 ns turn-on, 145 ns turn-off), and good channel isolation (-85 dB crosstalk at 1 MHz). It operates from a single supply of 10 V to 30 V or dual supplies of ±4.5 V to ±20 V, and is rated over the commercial temperature range of 0°C to 70°C. Typical uses include audio signal routing, data acquisition front ends, and test equipment multiplexing.

Supply voltage and temperature — fit check

The single-supply range of 10 V to 30 V covers common industrial and instrumentation rails. The dual-supply option (±4.5 V to ±20 V) lets the switch handle bipolar signals without level shifting.

It is ROHS3 compliant.
