Voltage Output, Unidirectional Measurement Current-Shunt Monitor
FEATURES
DESCRIPTION
D WIDE COMMON-MODE RANGE: −16V to +80V D CMRR: 120dB D ACCURACY:
The INA270 and INA271 family of current-shunt monitors with voltage output can sense voltage drops across current shunts at common-mode voltages from −16V to +80V, independent of the supply voltage. The INA270 and
− ±2.5mV offset (max)
INA271 pinouts readily enable filtering.
− ±1% gain error (max) − 20µV/°C offset drift (max) − 55ppm/°C gain drift (max)
The INA270 and INA271 are available with two output voltage scales: 14V/V and 20V/V. The 130kHz bandwidth simplifies use in current-control loops.
D BANDWIDTH: Up to 130kHz
The INA270 and INA271 operate from a single +2.
