3 Description

The

INA180-Q1,

INA2180-Q1,

and

INA4180-Q1

(INAx180-Q1) current sense amplifiers are designed

for cost-optimized applications. These devices are

part of a family of current-sense amplifiers (also

called current-shunt monitors) that sense voltage

drops across current-sense resistors at common-

mode voltages from –0.2 V to +26 V, independent of

the supply voltage. The INAx180-Q1 integrate a

matched resistor gain network in four, fixed-gain

device options: 20 V/V, 50 V/V, 100 V/V, or 200 V/V.

This matched gain resistor network minimizes gain

error and reduces the temperature drift.

All these devices operate from a single 2.7-V to 5.5-V

power supply. The single-channel INA180-Q1 draws

a maximum supply current of 260 µA; whereas, the

dual-channel INA2180-Q1 draws a maximum supply

current of 500 µA, and the quad channel draws a

maximum supply current of 900 µA.

The INA180-Q1 is available in a 5-pin, SOT-23

package with two different pin configurations. The

INA2180-Q1

is

available

in

an

8-pin,

VSSOP

package. The INA4180-Q1 is available in a 14-pin,

TSSOP package. All device options are specified

over the extended operating temperature range of

–40°C to +125°C.
