Overview

The TPA264x is a series of the newest high supply voltage amplifiers with 2-mV offset, low noise, and immunity to high-frequency noise from the power supply. It incorporates 3PEAK’s proprietary and patented design techniques to achieve excellent AC performance with a 1.5-MHz bandwidth, a 0.5-V/μs slew rate, and low distortion while drawing a quiescent current of only 550 μA per amplifier.

The input common-mode voltage range extends to −VS, and there is no internal ESD diode between the input and +VS. This feature can block the current path from the input to +VS during power-off but the signal is still in the input pin. It is widely used in battery-related applications.
