INA240A2PW Description

Short technical summary and product information.

The Texas Instruments INA240A2PW is a voltage-output, current-sense amplifier designed for sensing voltage drops across shunt resistors. It features an enhanced PWM rejection capability, allowing it to operate effectively in systems with significant common-mode transients.

 

This amplifier supports a wide common-mode voltage range from -4 V to 80 V, independent of the supply voltage. This negative common-mode capability is beneficial for applications like solenoid control where flyback voltages can occur.

 

Key electrical specifications include a maximum gain error of 0.20%, a gain drift of 2.5 ppm/°C, an offset voltage of ±25 µV, and an offset drift of 250 nV/°C. The device has a nominal gain of 50 V/V and a maximum quiescent current of 2.4 mA. It also boasts excellent Common Mode Rejection Ratio (CMRR) with 132 dB DC and 93 dB AC at 50 kHz.

 

The INA240A2PW is housed in a TSSOP-8 package and operates within an ambient temperature range of -40°C to 125°C. It is supplied on tape and reel in quantities of 2,000 units.
