Product Description

The INA199A1DCKR is a high-precision INA199 current sense amplifier designed for high-side current monitoring in automotive, industrial, and power management systems. This current shunt monitor integrates a fixed-gain (50 V/V) differential amplifier, supporting a wide common-mode voltage range of -0.3 V to +26 V. It operates from 2.7 V to 5.5 V supply voltage and delivers a rail-to-rail output for accurate current measurement across a shunt resistor. With a bandwidth of 110 kHz and low offset voltage (±150 µV), it ensures reliable detection in motor control, battery management, or load diagnostics. The device operates over -40°C to +125°C, featuring a compact SC70-6 package. Key advantages include excellent linearity, low quiescent current (100 µA), and simplified circuit integration. A limitation is the fixed gain, requiring external scaling for varied applications.
