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.

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.
