Overview

The INA600BIDBVR is a high-voltage, low-power difference amplifier designed for accurate voltage monitoring across wide common-mode ranges from -40V to +85V. It features a supply span up to 40V while maintaining a very low typical quiescent current of 65uA, making it ideal for battery-powered industrial and automotive systems.

Why Choose This Part

The device provides a high common-mode voltage range that significantly exceeds its own supply voltage, allowing for flexible power rail configurations. Its low power consumption of 65uA minimizes thermal load and battery drain, while the SOT-23-6 package offers a compact footprint for high-density PCB layouts.

Applications

Battery Cell Monitoring
Monitoring individual cell voltages in large battery energy storage systems (BESS) and EV battery packs.
High-Side Current Sensing
Measuring current across shunt resistors in high-voltage industrial AC/DC power supplies.
Solar String Inverters
Voltage sensing and bus monitoring in renewable energy power conversion stages.
EV Charging Stations
Providing isolated-like voltage measurements in DC fast charging power modules.

Getting Started

Engineers can evaluate this part using the INA600EVM evaluation module to verify performance in specific gain configurations. Design requires standard op-amp layout practices with decoupling capacitors placed close to the supply pins, and the wide input range allows direct connection to high-voltage rails without complex divider networks.
