DG303ACJ+

DG303ACJ+ is a TTL-compatible CMOS analogue switch that combines low-power operation with fast switching times and superior DC and AC switch characteristics. On-resistance is less than 50 ohm and is essentially constant over the analogue signal range. Device specifications are ideal for battery-powered circuitry. The switch control logic inputs are fully TTL and CMOS compatible. Also featured are “break-before-make” switching and low-charge injection. It is electrically compatible and pin-compatible with the original manufacturer’s devices. Applications include portable instruments, low-power sample/holds, power-supply switching, programmable gain amplifiers, SPDT and DPDT functions, process control and telemetry.
