Part Number: IVC102

Can the IVC102 operate on a single +3.3V supply (V-=0)? Or must V- be between -10V and -18V?

Hi Jeremy,

For proper operation of the device, dual supplies are required.
Can you provide some insight into your application / end equipment?

Galvanic oxygen sensors. Output is about 20nA at 10ppm oxygen. We've traditionally used transimpedance amps with 1M-Ohm gain - looking for something new. I was curious if I could lose the negative supply. I will be testing the IVC102 with dual supplies next week.
