Description
28
VDRIVE
Logic Power Supply Input. The voltage supplied at this pin determines the operating voltage for the serial
interface of the AD7877.
29
ARNG
When the DAC is in current output mode, a resistor from ARNG to GND sets the output range.
30
AOUT
Analog Output Voltage or Current from DAC.
31
VREF
Reference Output for the AD7877. The internal 2.5 V reference is available on this pin for use external to the
device. The reference output must be buffered before it is applied elsewhere in a system. To reduce system
noise effects, it is strongly recommended to place a capacitor of 100 nF between the VREF pin and GND.
Alternatively, an external reference can be applied to this input. The voltage range for the external reference is
1.0 V to VCC. For the specified performance, it is 2.5 V on the AD7877.
