Product Overview
The INA193 from Texas Instruments is a current shunt monitor for Signal_Chain designs. For the INA193 variant, the specified gain is 20 V/V and the pinout is Pinout #1. The V+ supply pin operates from 2.7 V to 18 V, while the functional common-mode input voltage range extends from -16 V to +80 V.
The device is offered in the DBV 5-pin SOT-23 package, with a 2.90 mm x 1.60 mm nominal body. Thermal data for this package includes 221.7°C/W junction-to-ambient resistance, 144.7°C/W junction-to-case top resistance, and 49.7°C/W junction-to-board resistance. Absolute maximum ratings include 18 V maximum supply voltage, 150°C maximum junction temperature, and -65°C to +150°C storage temperature.
Electrical parameters include 500 kHz bandwidth at CLOAD=5 pF, 1 V/us typical slew rate, 2 us typical settling time, and 40 nV/sqrt(Hz) typical input-referred voltage noise density. The device is specified across -40°C to +125°C and supports current-sense applications requiring defined gain error, common-mode rejection, output swing, capacitive-load limits, and supply-current limits.
