3PEAK TPA191A2-SC6R Bidirectional Current Sense Amplifier PIO | DigiKey
The TPA191A2-SC6R from 3PEAK is a bidirectional current sense amplifier designed for precision current measurement in battery chargers, power management systems, and telecom equipment. Operating from a single 2.7 V to 36 V supply, it draws a typical supply current of 80 μA. The amplifier supports a wide common-mode voltage range from -0.3 V to 36 V, making it versatile for high-side and low-side current sensing. With five fixed gain options (20 V/V, 50 V/V, 75 V/V, 100 V/V, and 200 V/V), it ensures accurate measurements. Its zero-drift architecture minimizes offset and gain errors, with a maximum offset voltage of ±50 μV at 2.75 V and ±180 μV at 12 V, and an offset drift of 0.2 μV/°C. The device operates over an industrial temperature range of -40°C to +125°C and is available in a compact SOT363 package.
