General Description Maxims DG381-DG390 and DG381A-DG390A CMOS dual and quad analog switches combine low power operation with fast switching times and superior DC and AC switch characteristics. On resistance is less than 509 and is essentially constant over the analog signal range. Device specifications are ideal for battery powered circuitry. These switches are available in a variety of formats as outlined below 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. Maxims DG381-DG390 and DG381A-DG390A families are electrically compatible and pin compatible with the original manufacturer's devices. All devices will PART TEMP.

Switching Time Test Circuit. Application Information All DG381 family switches will operate with +5 to +15V power supplies. They can also be used with single ended power supplies ranging from +10V to +30V where the V- terminal is connected to ground. In either case analog signals ranging from V* to V~ can be switched. Table 1. Typical Single Supply Parameters The on resistance variation with analog signal and supply voltage is shown in the Typical Operating Characteristics graphs. The temperature coefficient of Roy is typically 0.5%/C. Typical on resistance matching from channel to channel is 10%.
