General Description
Maxim’s DG300–DG303 and DG300A–DG303A 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 50Ω and is essentially constant over the analog signal range. Device specifications are ideal for battery­powered circuitry.
These switches are 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.
Maxim’s DG300-DG303 and DG300A-DG303A families are electrically compatible and pin compatible with the original manufacturer’s devices. All devices operate with power supplies ranging from ±5V to ±18V. Single-sup­ply operation is implemented by connecting V- to GND.

Applications Information
All DG300 family switches will operate with ±5V to ±15V power supplies. They can also be used with single-ended power supplies ranging from +10V to +30V where the V­terminal is connected to ground. In either case, analog signals ranging from V+ to V- can be switched.
The on-resistance variation with analog signal and supply voltage is shown in the Typical Operating Characteristics. The temperature coefficient of RONis typically 0.5%/°C. Typical on-resistance matching from channel to chan­nel is 10%. In addition, Table 1 outlines some typical parameters for single-supply operation.
The charge injection test circuit is shown in Figure 1. Table 2 lists the typical injected charge for DG300 series switches with various input voltages.
