Question I'm looking for an equivalent part to AD7812 but one which can accept a +/-
input. Preferably pin compatible. Answer The analog input channels can be configured as pseudo differential
channels..refer to page 9 of the datasheet for more details. We don’t have
bipolar input range ADC‘s in the 10 bit space. The closest to the AD7812 would
be the parts that are available in the general purpose 100KSPS to 1MEGSPS 12
bit resolution. Refer to the selection guide on analog.com for a full listing.
