Typical Operating Characteristics
(VRS+ = VRS- = 3.6V, TA = +25°C, unless otherwise noted.)
ELECTRICAL CHARACTERISTICS (continued)
(VRS+ = VRS- = 3.6V, VSENSE = (VRS+ - VRS-) = 0V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2: VOUT = 0. ICC is the total current into RS+ plus RS- pins.
Note 3: VOS is extrapolated from measurements for the gain-error test.
Note 4: Gain error is calculated by applying two values of VSENSE and calculating the error of the slope vs. the ideal:
Gain = 25, VSENSE is 20mV and 120mV.
Gain = 50, VSENSE is 10mV and 60mV.
Gain = 100, VSENSE is 5mV and 30mV.
Gain = 200, VSENSE is 2.5mV and 15mV.
Note 5: The device is stable for any external capacitance value.
Note 6: VOH is the voltage from VRS- to VOUT with VSENSE = 3.6V/gain.
