INA250A2 Description

Short technical summary and product information.

The Texas Instruments INA250A2 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.

Key specifications include a maximum common-mode voltage of 36 V and a minimum of 0 V. The device features a 2 mΩ integrated shunt resistor with 0.1% tolerance and a temperature coefficient of 10 ppm/°C. The gain error for the shunt and amplifier is a maximum of 0.3%, with a gain error drift of 45 ppm/°C. The bandwidth can reach up to 50 kHz, and the quiescent current is a maximum of 0.3 mA.

This bidirectional current-shunt monitor supports low-side or high-side measurements. It is available in multiple gain options, including 200 mV/A (INA250A1), 500 mV/A (INA250A2), 800 mV/A (INA250A3), and 2 V/A (INA250A4). The operating temperature range is -40°C to 125°C.

The INA250A2 is housed in a 16-pin TSSOP package with dimensions of 5 mm × 6.4 mm, covering an area of 32 mm². This package is suitable for surface mounting.
