High-Precision, Low-Voltage, Current-Sense Amplifier
with Current Output and Chip Select for Multiplexing
ELECTRICAL CHARACTERISTICS (continued)
(VCC = 3.3V, VRS+ = VRS- = 3.0V, VSENSE = 0, VCM = (VRS+ + VRS-)/2, VCS = 3.3V, ROUT = 10kΩ to GND for unidirectional operation,
ROUT = 10kΩ to VCC/2 for bidirectional operation. TA = -40°C to +125°C, unless otherwise noted. Typical values are at TA = +25°C.)
