Product Summary

The DG303AAK is a CMOS dual and quad analog switch. It combines low power operation with fast switching times and superior DC and AC switch characteristics. On-resistance is less than 50Ω and is essentially constant over the analog signal range. Device specifications are ideal for batterypowered circuitry. The DG303AAK switch is available in a variety of formats as outlined in the Pin Configurations section. The switch control logic inputs are fully TTL and CMOS compatible. Also featured are break-before-make switching and low charge injection. The DG303AAK is electrically compatible and pin compatible with the original devices. All devices operate with power supplies ranging from ±5V to ±18V. Single-supply operation is implemented by connecting V- to GND.
