3 Description

The INA193

−INA198 family of current shunt monitors

with voltage output can sense drops across shunts at

common-mode voltages from

−16 V to +80 V,

independent of the INA19x supply voltage. They are

available with three output voltage scales: 20 V/V, 50

V/V, and 100 V/V. The 500 kHz bandwidth simplifies

use in current control loops. The INA193

−INA195

devices provide identical functions but alternative pin

configurations

to

the

INA196

−INA198

devices,

respectively.

The INA193

−INA198 devices operate from a single

2.7-V to 18-V supply, drawing a maximum of 900 μA

of supply current. They are specified over the

extended operating temperature range (

−40°C to

+125°C), and are offered in a space-saving SOT-23

package.
