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.

Charge Injection (±15V Supplies) 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. ANALOG INPUT (V) The on-resistance variation with analog signal and supply voltage is shown in the Typical Operating Characteristics. The temperature coefficient of RON is typically 0.5%/°C. Typical on-resistance matching from channel to channel is 10%.
