INA271

INA270 INA271 SBOS381 − FEBRUARY 2007 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 +2.7V to D TWO TRANSFER FUNCTIONS AVAILABLE: − 14V/V (INA270) − 20V/V (INA271) D QUIESCENT CURRENT: 900µA (max) +18V supply, drawing a maximum of 900µA of supply current. They are specified over the extended operating temperature range of −40°C to +125°C and are offered in an SO-8 package.
