INA271-HT
www.ti.com SBOS521D – SEPTEMBER 2010 – REVISED AUGUST 2013 VOLTAGE OUTPUT, UNIDIRECTIONAL MEASUREMENT CURRENT-SHUNT MONITOR
Check for Samples: INA271-HT FEATURES DESCRIPTION The INA271 is a current-shunt monitor with voltage
output and can sense drops across current shunts at
common-mode voltages from –16V to +80V,
independent of the supply voltage. The INA271
pinouts readily enable filtering. 1 Wide Common-Mode Range: –16V to +80V
CMRR: 78dB
Accuracy:
В±10mV Offset (max)
В±7.5% Gain Error (max)
100ОјV/В°C Offset Drift (max)
Bandwidth: Up to 130kHz
Transfer Function: 20V/V
Quiescent Current: 1600ОјA (max)
Power Supply: +2.7V to +18V
Provision for Filtering The INA271 is available with a 20V/V output voltage
scale. The 130kHz bandwidth simplifies use in
current-control loops.
The INA271 operates from a single +2.7V to +18V
supply, drawing a maximum of 1600ОјA of supply
current. This device is specified over the extended
operating temperature range of –55В°C to +210В°C. …
