DG302ACJ+

The Analog Devices DG302ACJ+ is a monolithic low-power CMOS dual analog switch designed for applications requiring fast switching times and superior DC and AC characteristics. With an on-resistance of less than 50 Ohms, it is suitable for battery-powered circuitry.

This device features dual DPST (Double Pole Single Throw) normally open circuits. It operates with power supplies ranging from ±5V to ±18V, and can also function with a single supply by connecting V- to GND. The switch control logic inputs are fully TTL and CMOS compatible. Key electrical specifications include a fast switching time of 300ns (on) and 250ns (off), low charge injection of 12pC, and minimal crosstalk of -74dB at 500kHz.

The DG302ACJ+ is housed in a 14-pin DIP (Dual In-line Package) with a 0.300" body width, designed for through-hole mounting. Its operating temperature range is 0°C to 70°C (TA). This component is electrically and pin compatible with original manufacturer's devices, making it a reliable second source.

Applications for this analog switch include portable instruments, low-power sample/holds, power-supply switching, programmable gain amplifiers, SPDT and DPDT functions, and process control and telemetry systems.
