DG212DY

The DG212DY from Analog Devices is a low-cost, monolithic quad SPST CMOS analog switch designed for general-purpose switching applications. It offers a 15-V analog signal range and a breakdown voltage rating of 40 V. The device features an on-resistance of 175 Ohms and a continuous current rating of 20 mA.

Designed with CMOS technology, the DG212DY provides low power dissipation and TTL compatibility. Its logic inputs can accept negative voltages, simplifying the interface. The switches offer true bi-directional performance in the on condition and block signals up to 30 V peak-to-peak in the off condition.

This analog switch is available in a 16-SOIC package and is suitable for surface mounting. The operating temperature range is -40°C to 85°C. Applications include disk drives, test equipment, communication systems, and sample-and-holds.

Key electrical characteristics include an off-state isolation of 70 dB, a maximum leakage current of 5 nA, and channel capacitance of 5 pF. Switching times are also specified, with a switch-on time of up to 1000 ns and a turn-off delay of 500 ns.
