Quad, SPST Analog Switches
DG308A/DG309
_______________General Description
The DG308A/DG309 are quad, single-pole-single-throw (SPST) analog switches. The DG308A is normally open (SPST, NO), while the DG309 is normally closed (SPST, NC). Both parts feature fast switching speeds and low onresistance over the analog range. Other features include a turn-on time under 120ns, a turn-off time under 90ns, and a channel on-resistance of 60Ω.
CMOS inputs provide reduced input loading and very low leakage currents. Both parts feature a 44V maximum breakdown
voltage rating that allows 30V peak-to-peak switch-off blocking capacity. The DG308A/DG309 can be used with split supplies (±5V to ±20V) or a single positive supply (+5V to +30V), while retaining
CMOS-logic-compatible inputs.
