DG300(A)/DG301(A)/DG302(A)/DG303(A)
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 R
ON
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.
