INA190A1IDDFR Description

Short technical summary and product information.

The Texas Instruments INA190A1IDDFR is an ultra-precise, bidirectional current sense amplifier. It is designed for applications requiring accurate current monitoring over a wide dynamic range.

 

Key electrical specifications include a maximum common-mode voltage of 40V and a minimum of -0.2V. The amplifier offers multiple gain options, with the A1 device providing a gain of 25 V/V. It boasts a high common-mode rejection ratio (CMRR) of 132 dB (min) and a low input offset voltage of ±15 µV (max). The gain error is ±0.2% (A1 device), and the gain error drift is a maximum of 7 ppm/°C.

 

This device operates within a temperature range of -40°C to 125°C. It features low input bias currents of 500 pA (typ), enabling microamp current measurements. The supply voltage range is 1.7V to 5.5V, with a low shutdown current of 100 nA (max) and a quiescent current of 50 µA (typ) at 25°C.

 

The INA190A1IDDFR is available in SOT-23-THN, SOT-SC70, and UQFN packages, suitable for various board space constraints.
