Vishay – DG2501/02/03: Monolithic Quad SPST Analog Switches

The DG2501, DG2502, and DG2503 are monolithic quad single-pole single-throw (SPST) analog switches that are fully specified at 3V and 5V. The parts feature low parasitic capacitance, low charge injection, and low leakage performance over the full operating temperature range of -40°C to +85°C. The DG2501, DG2502, and DG2503 each feature four independently selectable SPST switches with closely matched channel resistance. The DG2501 is normally closed, while the DG2502 is normally open. The DG2503 has two normally open and two normally closed switches.
