The INA270A-Q1 and INA271A-Q1 (INA27xA-Q1) family of current-shunt monitors with voltage output can sense voltage drops across current shunts at common-mode voltages from –16?V to +80?V, independent of the supply voltage. The INA27xA-Q1 pinouts readily enable filtering.
The INA27xA-Q1 devices are available with two output voltage scales: 14?V/V and 20?V/V. The 130-kHz bandwidth simplifies use in current-control loops.
The INA27xA-Q1 operates from a single 2.7-V to 18-V supply, drawing a maximum of 900?μA of supply current. They are specified over the extended operating temperature range of –40°C to +125°C and are offered in an SOIC-8 package.
