5. For optimum performance, VREF+ should always be less than (V+) - 0.2 volts to prevent saturation of the VREF+ input buffer.

6. Specification is for MCLK = 8MHz and 5 kSps conversion rate. MCLK frequency and conversion rate affect power consumption.

See Section 3.2 Power Consumption for more details.

7. 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

the same voltage potential.
