Now at Mouser: Texas Instruments INA290 Ultra-Precise Current Sense Amplifiers

September 10, 2020 - Mouser Electronics, Inc., the industry's leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the INA290 ultra-precise current sense amplifiers from Texas Instruments.

Texas Instruments INA290 ultra-precise current sense amplifiers can measure voltage drops across shunt resistors over a wide common-mode range from 2.7V to 120V. It is in a highly space-efficient SC-70 package with a PCB footprint of only 2.0mm × 2.1mm. The ultra-precise current measurement accuracy is achieved thanks to the combination of an ultra-low offset voltage of ±12µV (maximum), a small gain error of ±0.1% (maximum), and a high DC CMRR of 160dB (typical). The INA290 is not only designed for DC current measurement but also high-speed applications (like fast overcurrent protection, for example) with high bandwidth of 1MHz (at a gain of 20V/V) and an 85dB AC CMRR (at 50kHz).

Applications for the INA290 current sense amplifiers include active antenna systems mMIMO (AAS), macro remote radio units (RRU), 48V rack servers, 48V merchant network and server power supplies, and test and measurement devices.
