INA241B3IDDFR Description

Short technical summary and product information.

The Texas Instruments INA241B3IDDFR is an analog current sense amplifier designed for high-precision measurements. It features bidirectional operation and enhanced Pulse Width Modulation (PWM) rejection, making it suitable for systems with switching common-mode voltages up to 125kHz.

This amplifier supports a wide operational common-mode voltage range from -5V to 110V, with a survival voltage of -20V to 120V. Key electrical characteristics include a high small-signal bandwidth of 1.1MHz at all gains, a slew rate of 8V/µs, and a step response settling time to 1% of 1µs. The device offers multiple voltage gain options (10, 20, 50, 100, 200 V/V) and boasts excellent common-mode rejection ratios, with 120dB minimum DC-CMRR.

Available in SOT-23-8, VSSOP-8, and SOIC-8 surface mount packages, the INA241B3IDDFR operates within an industrial temperature range of -40°C to 125°C. Its high precision is further supported by a maximum gain error of 0.1% and a gain error drift of ±5 ppm/°C for the B version. The maximum input offset voltage is ±150 µV with a drift of ±0.5 µV/°C.
