TIINA199B1DCKT

Overview

The INA199B1DCKT is a high-side or low-side current-shunt monitor designed for voltage-output applications with common-mode voltages from -0.3V to 26V. This zero-drift amplifier offers high accuracy with a 1 percent maximum error and a low offset, allowing for small shunt resistors to minimize power loss. Its low 100uA quiescent current makes it highly suitable for power-constrained and battery-operated systems.

Why Choose This Part

The device features a zero-drift architecture that ensures high accuracy even with full-scale shunt drops as low as 10-mV. It comes in a space-saving SC70-6 package, making it ideal for dense PCB layouts while maintaining a wide operating temperature range from -40C to 125C.

Applications

Getting Started

To evaluate this part, use the INA199EVM evaluation module which provides test points for the shunt input and gain output pins. When designing the PCB, place a decoupling capacitor close to the supply pin and use Kelvin connections for the shunt resistor to maintain 1 percent accuracy.
