High-Precision, Low-Voltage, Current-Sense Amplifier
with Current Output and Chip Select for Multiplexing
Typical Operating Characteristics
(VCC = 3.3V, VRS+ = VRS- = 3.0V, VSENSE = 0, CL = 1000pF, ROUT = 10kΩ to GND for unidirectional operation, ROUT = 10kΩ to VCC/2
for bidirectional operation. TA = +25°C, unless otherwise noted.)
