TIINA199B1DCKR

Overview

The INA199B1DCKR is a zero-drift, bidirectional current-shunt monitor designed to measure voltage across shunts at common-mode voltages from -0.3V to 26V. This specific B1 variant provides a fixed gain of 50V/V in a compact SC-70 package, making it ideal for space-constrained power monitoring.

Why Choose This Part

The zero-drift architecture ensures high accuracy with a 1.5 percent maximum error across the full temperature range of -40C to 125C. Its low quiescent current of 0.1mA and wide common-mode range facilitate efficient high-side sensing without needing separate power supplies.

Applications

Getting Started

To evaluate this part, use the INA199EVM evaluation module which supports multiple shunt configurations. Ensure the shunt resistor is placed close to the IN+ and IN- pins to minimize trace resistance errors, and decouple the supply pin with a 0.1uF ceramic capacitor.
