TIINA199B1RSWR
Overview
The INA199B1RSWR is a voltage-output, current-shunt monitor designed for bidirectional current sensing across a wide common-mode range of -0.3V to 26V. This zero-drift amplifier offers high accuracy with a 1.5 percent maximum gain error and a low quiescent current of 100uA, making it suitable for power-sensitive monitoring in compact electronics.
Why Choose This Part
The zero-drift architecture ensures high precision over the full temperature range of -40C to 125C with minimal offset. Its exceptionally low 100uA quiescent current and small UQFN-10 footprint make it ideal for portable, battery-powered applications requiring high-side or low-side sensing.
Applications
Key Specifications
Getting Started
To evaluate this part, use the INA199EVM evaluation module which provides test points for the shunt resistor and output voltage. 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 capacitor.
