Description

V+

Positive Power Supply Line for the ADC Driver and Reference Buffer. This pin can be tied to VDD as

long as headroom for the reference buffer is maintained. This pin requires a 100 nF capacitor to GND

for best operation.

REF

External Reference Signal. REF is the noninverting input of on-board reference buffer. Connect an external

reference source to this pin. A low-pass filter may be required between the reference source and this pin to

band limit noise generated by the reference source.

REF_OUT

Reference Buffer Output. This pin provides access to the buffered reference signal presented to the ADC.

AI is analog input, AO is analog output, P is power, DI is digital input, and DO is digital output.
