DESCRIPTION
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鈭? 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
碌A,
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鈭?
and SOT23鈭? and are specified for the 鈭?0擄C to +125擄C
temperature range.
