Overview

The TPA9151-SO1R is a specialized amplifier IC from 3PEAK designed for current sensing, monitoring, and control applications. It operates over a wide supply range of 2.25V to 18V and features integrated EMI enhancement to maintain signal integrity in noisy industrial environments. With a 500kHz bandwidth and a 10V/us slew rate, it is well-suited for dynamic current measurement tasks.

Why Choose This Part

The TPA9151-SO1R provides robust performance with a high 100mA output current capability and built-in EMI protection. Its wide operating temperature range from -40C to 125C ensures reliability in harsh thermal conditions, while the low 3500uA quiescent current supports energy-efficient designs.
