the same voltage potential.
For optimum performance, VREF+ should always be less than (V+) - 0.2 volts to prevent saturation of the VREF+ input buffer.
Specification is for MCLK = 8MHz and 5 kSps conversion rate. MCLK frequency and conversion rate affect power consumption.
Tested with 100 mVP-P on any supply up to 2 kHz. V1+ and V2+ supplies at the same voltage potential, V1- and V2- supplies at
