Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2: VOS is extrapolated from two point transconductance and gain accuracy tests. Measurements are made at VSENSE =
+5mV and VSENSE = +50mV for MAX992_F. These measurements are also used to test the full-scale sense voltage,
transconductance, and gain. These VOS specifications are for the trimmed direction only (VRS+ > VRS-). For current flowing
in the opposite direction (VRS- > VRS+), VOS is ±1mV (max) at +25°C and ±1.8mV (max) over temperature, when VRS+ is at
3.6V. See the
Detailed Description for more information.
Note 3: Guaranteed by common-mode rejection ratio. Extrapolated VOS as described in Note 2 is used to calculate common-mode
rejection ratio.
Note 4: Includes input bias current of SIGN comparator.
Note 5: Leakage in to RS+ or RS- when VCC = 0V. Includes input leakage current of SIGN comparator. This specification does not
add to the bias current.
Note 6: Output voltage should be 650mV below VCC to achieve full accuracy.
Note 7: IOL is the minimum output current in the VSENSE - IOUT transfer characteristics. VOL is the minimum output voltage in the
VSENSE - VOUT transfer characteristic.
Note 8: VSENSE voltage required to switch comparator.
Note 9: Discharge to charge trip point is functionally tested at VCM = -0.1V, +3.6V, and +28V.
Note 10: Guaranteed by PSRR test. Extrapolated VOS as described in Note 2 is used to calculate the power-supply rejection ratio.
VSENSE has to be such that the output voltage is 650mV below VCC to achieve full accuracy.
