INA250A1PWR Description

Short technical summary and product information.

The Texas Instruments INA250A1PWR is a voltage-output, current-sensing amplifier family that integrates an internal shunt resistor. This design enables high-accuracy current measurements at common-mode voltages that can vary from 0 V to 36 V, independent of the supply voltage.

This device functions as a bidirectional, low- or high-side current-shunt monitor. It features a 2 mΩ integrated shunt resistor with 0.1% tolerance and a temperature coefficient of 10 ppm/°C. The INA250A1 variant offers a gain of 200 mV/A, with a maximum gain error of 0.3% (shunt and amplifier combined).

The operating temperature range is specified from -40°C to 125°C, ensuring reliable performance in various environments. The common-mode voltage range extends from -0.1 V to 36 V. The amplifier is housed in a 16-pin TSSOP package with a package area of 32 mm².

Key electrical specifications include a maximum common-mode voltage of 36V, a minimum common-mode voltage of 0V, and a maximum input offset of 100,000 µV. The gain error is a maximum of 0.75%, with a gain error drift of 45 ppm/°C. The CMRR is a minimum of 100 dB, and the bandwidth can reach up to 50 kHz. The quiescent current (Iq) is a maximum of 0.3 mA.
