8.2.2.2.1 External Components
The following external components are required in order to configure the PGA300 for a 0-V to 10-V absolute voltage output:
- Place a 100-nF capacitor from the PWR pin to ground, as close as possible to the PWR pin.
Do not exceed the maximum slew rate of 0.5 V/µs at the PWR pin.
- Place a 100-nF capacitor from the AVDD pin to ground, as close as possible to the AVDD pin.
- Place a 100-nF capacitor from the DVDD pin to ground, as close as possible to the DVDD pin.
- Place a capacitor between 10 nF and 1000 nF from the REFCAP pin to ground, as close as possible to the REFCAP pin.
- Implement compensation, using the COMP pin and an isolation resistor, when driving large capacitive loads with the OUT pin.
