DG308A and DG309 Switches

Analog Devices' DG308A/DG309 are quad, single-pole-single-throw (SPST) analog switches

Image of Analog Devices' DG308A/DG309Analog Devices' DG308A is a normally open (SPST, NO) switch, while the DG309 is normally closed (SPST, NC). Both parts feature fast switching speeds and low on-resistance over the analog range. Other features include a turn-on time under 120 ns, a turn-off time under 90 ns, and a channel on-resistance of 60 Ω. CMOS inputs provide reduced input loading and very low leakage currents.

Both parts feature a 44 V maximum breakdown voltage rating that allows 30 V peak-to-peak switch-off blocking capacity. The DG308A/DG309 can be used with split supplies (±5 V to ±20 V) or a single positive supply (+5 V to +30 V), while retaining CMOS-logic-compatible inputs.
