We are looking to use the AD5412 with I and V out going to the same pin. I notice they call out using a buffer amplifier on the V+sense line in this case. Our device has an input range of 12 to 30V which will be used to power the AD5412 as well the V+ and V- of the amplifier. Can I use the OP07 recommended buffer amp in this case? Thanks.
The following part would suit your needs.
The OP290 is a high performance micropower dual op amp that operates from a single supply of +1.6V to +36V or from dual supplies of ±0.8V to ±18V. Input voltage range includes the negative rail allowing the OP290 to accommodate input signals down to ground in single supply operation.
