Note 3: All devices are 100% production tested at TA = +25°C. Temperature limits are guaranteed by design and/or characterization.

Note 4: Gain and offset voltage are calculated based on two point measurements: VSENSE1 = 10mV and VSENSE2 = 100mV.

Note 5: VOS, VOL, CMRR, and PSRR are measured with the charge pump off.

Note 6: Guaranteed by design and/or characterization.

Note 7: The maximum VSENSE of the MAX9643T is 400mV. With the gain = 2.5V/V, the output swing high is not applicable to the

MAX9643T.
