INA168 Description

Short technical summary and product information.

The Texas Instruments INA168 is a high-side, unipolar current shunt monitor designed for precise current measurement applications. It operates across a wide supply and common-mode voltage range, from 2.7V to 60V, making it suitable for various systems.

 

Key electrical specifications include an adjustable voltage gain, a typical quiescent current of 25µA, and a bandwidth of 32kHz. The device is specified for an operating temperature range of -40°C to +125°C.

 

Packaged in a compact SOT-23-5 surface-mount case, the INA168 is ideal for applications requiring efficient space utilization. Its independent supply and input common-mode voltages, along with a single resistor gain set, offer design flexibility.

 

Applications include automotive, telephone, and computer systems, portable and battery-backup systems, battery chargers, power management, and cell phones.
