INA240A3DR Description

Short technical summary and product information.

The Texas Instruments INA240A3DR is a precise current-sense amplifier designed for a wide operating common-mode voltage range of -4 V to 80 V. This device features enhanced Pulse Width Modulation (PWM) rejection, providing high suppression for common-mode transients.

 

Key electrical specifications include a maximum gain error of 0.20% and a gain drift of 2.5 ppm/°C. The offset voltage is a maximum of ±25 µV with an offset drift of 250 nV/°C. This specific part, INA240A3DR, offers a gain of 100 V/V. The quiescent current is a maximum of 2.4 mA.

 

With excellent Common-Mode Rejection Ratio (CMRR), including 132-dB DC CMRR and 93-dB AC CMRR at 50 kHz, the INA240A3DR ensures accurate current sensing even in noisy environments. The amplifier is housed in an 8-pin SOIC package suitable for surface mounting.

 

This bidirectional amplifier is suitable for applications requiring precise current monitoring across a broad voltage spectrum, including systems with high common-mode transients.
