6 / 10 page 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 V- terminal 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 RON is typically 0.5%/°C. Typical on-resistance matching from channel to chan- nel 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.
