INA191A4IYFDR Description

Short technical summary and product information.

The Texas Instruments INA191A4IYFDR is an analog output current sense amplifier with a maximum common-mode voltage of 40V and a minimum of -0.2V. It features a low input offset voltage of ±12µV maximum and a low input offset drift of 0.01µV/°C typical. The device offers multiple voltage gain options, including 25, 50, 100, 200, and 500 V/V, with a maximum gain error of 0.25% and a gain error drift of 7 ppm/°C.

 

This amplifier operates with a supply voltage range of 1.7V to 5.5V and has a low quiescent current of 43µA at 25°C. It also features low input bias currents of 100pA typical, enabling microamp current measurements. The operating temperature range is -40°C to 125°C.

 

The INA191A4IYFDR is available in a small WCSP package, specifically the DSBGA (YFD) package with an area of 0.895 mm². This compact size makes it suitable for space-constrained applications. The device is designed for low-side current sensing capabilities and offers high CMRR of 132 dB.
