Product Description

The INA199A1DCKT is a high-precision INA199 current monitor and current sensor designed for accurate current sensing applications. Housed in a compact SC70-6 package, this bidirectional current amplifier operates over a wide voltage range of 2.7V to 26V, making it suitable for industrial systems like power management, battery monitoring, and motor control. It features a fixed gain of 50 V/V, enabling direct interfacing with standard ADC modules without additional amplification. With an input offset voltage as low as 150 µV, the INA199A1 ensures precise current measurements through a shunt resistor. Its -40°C to +125°C operating temperature range supports harsh environments. The device delivers real-time analog output proportional to load current, requiring minimal external components. Key advantages include low quiescent current (100 µA) and robust ESD protection, while its limited bandwidth (130 kHz) suits applications not requiring ultra-fast response. Optimized for space-constrained designs, it reliably measures currents from milliamps to amps depending on shunt resistor selection.
