Overview

The INA213BIDCKR is a high-accuracy, zero-drift current shunt monitor designed to sense drops across shunts at common-mode voltages from -0.3V to 26V. This voltage-output, current-sense amplifier features a fixed gain of 50V/V and is housed in a compact SC-70-6 package for space-constrained designs.

Why Choose This Part

The device offers a low supply current of 100uA (max) and a zero-drift architecture that ensures high accuracy across the full -40C to 125C temperature range. Its wide common-mode range allows for both high-side and low-side sensing, while the integrated gain resistors simplify PCB layout and reduce BOM count.

Applications

Notebook and Mobile Power Management
Monitoring battery discharge and charging currents in portable electronics.
Telecom Infrastructure
High-side current monitoring in line cards and power distribution units.
Precision Sensor Nodes
Utilizing the zero-drift architecture for stable current measurements in variable temperature environments.

Getting Started

To evaluate this part, designers often use the INA213EVM evaluation module. Ensure the shunt resistor is placed close to the IN+ and IN- pins to minimize trace resistance errors, and provide a bypass capacitor on the V+ supply pin.
