ELECTRICAL CHARACTERISTICS

VRS+ = VRS- = 3.6V; VSENSE = (VRS+ - VRS-) = 0V; COUT = 47nF; TA = -40°C to +105°C, unless otherwise noted.

Typical values are at TA = +25°C. See Note 1

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

characterization.

Note 2: Extrapolated to VOUT = 0. ICC is the total current into the RS+ and the RS- pins.

Note 3: Input offset voltage VOS is extrapolated from VOUT with VSENSE set to 1mV.

Note 4: Gain error is calculated by applying two values for VSENSE and then calculating the error of the actual slope vs. the

ideal transfer characteristic:

For GAIN = 25, the applied VSENSE is 20mV and 120mV.

For GAIN = 50, the applied VSENSE is 10mV and 60mV.

For GAIN = 100, the applied VSENSE is 5mV and 30mV.

For GAIN = 200, the applied VSENSE is 2.5mV and 15mV.

Note 5: The device is stable for any capacitive load at VOUT.

Note 6: VOH is the voltage from VRS- to VOUT with VSENSE = 3.6V/GAIN.
