TS4972EIJT

Overview

The TS4972EIJT is a monolithic audio power amplifier manufactured by STMicroelectronics, designed for mobile and portable applications. It delivers 1.6W of continuous RMS output power into a 4Ω load at VCC = 5V. The device operates from a supply voltage range of 2.5V to 5.5V and features rail-to-rail output capability. Key electrical parameters include an ultra-low standby current of 10nA, a power supply rejection ratio (PSRR) of 75dB at 217Hz, and total harmonic distortion (THD) of 0.05%. It utilizes a flip-chip package with 8 x 300µm bumps.

Feature Summary

• Ultra-low consumption in standby mode
• Rail-to-rail output capability
