FEATURES

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−8 and

SOT23 packaging enable use in a variety of applications.

(1)

Qualification in Accordance With AEC-Q100

Qualified for Automotive Applications

Customer-Specific Configuration Control Can

Be Supported Along With Major-Change

Approval

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.

ESD Protection Exceeds 2000 V Per

MIL-STD-883, Method 3015; Exceeds 200 V

Using Machine Model (C = 200 pF, R = 0)

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.
