PROVISION FOR FILTERING
DESCRIPTION
The INA270 and INA271 family of current-shunt
monitors with voltage output can sense drops across
current shunts at common-mode voltages from –16V
to +80V, independent of the supply voltage. The
INA270 and INA271 pinouts readily enable filtering.

Voltage Output, Unidirectional Measurement
Current-Shunt Monitor
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.
The INA270 and INA271 operate from a single +2.7V
to +18V supply, drawing a maximum of 900
μ
A 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.
