The INA139 and INA169 are high-side, unipolar, current
shunt monitors. Wide input common-mode voltage range,
high-speed, low quiescent current, and tiny TSSOP−8 and
SOT23 packaging enable use in a variety of applications.
Input common-mode and power-supply voltages are
independent and can range from 2.7 V to 40 V for the
INA139 and 2.7 V to 60 V for the INA169. Quiescent
current is only 60 µA, which permits connecting the power
supply to either side of the current measurement shunt
with minimal error.
The device converts a differential input voltage to a current
output. This current is converted back to a voltage with an
external load resistor that sets any gain from 1 to over 100.
Although designed for current shunt measurement, the
circuit invites creative applications in measurement and
level shifting.
Both the INA139 and INA169 are available in TSSOP−8
and SOT23−5 and are specified for the −40°C to +125°C
temperature range.
