TIINA181A3IDBVT
Overview
The INA181A3IDBVT is a cost-effective, bidirectional current sense amplifier designed for high-side or low-side sensing. It features a fixed gain of 100V/V and supports a wide common-mode voltage range from -0.2V to 26V. This amplifier is capable of operating at supply voltages between 2.7V and 5.5V while drawing only 260uA of quiescent current.
Why Choose This Part
The device offers a high 350 kHz bandwidth and a 2V/us slew rate, making it suitable for fast-switching control loops. Its rail-to-rail output and wide common-mode range allow for flexible placement in the circuit, while the low 260uA supply current minimizes power overhead in battery-operated designs.
