Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.

Note 2: Guaranteed by PSR test.

Note 3: Guaranteed by OUT Voltage Error test.

Note 4: Output voltage is internally clamped not to exceed 12V.

Note 5: VOS is extrapolated from the gain accuracy tests.

Note 6: Total OUT voltage error is the sum of gain and offset voltage errors.

Note 7: Measured at IOUT = -500µA (RLOAD = 4kΩ for gain = 20V/V, RLOAD = 10kΩ for gain = 50V/V, RLOAD = 20kΩ for gain =

100V/V).

Note 8: 6.25mV = 1/16 of 100mV full-scale voltage (C/16).

Note 9: The device will not reverse phase when overdriven.
