TPA3100D2RGZT Integrated Circuits (ICs)

Introduction

TPA3100D2RGZT is a monolithic integrated circuit that acts as an audio amplifier. It is a power amplifier that uses MOSFETs as the output transistors and can be used for single-ended or bridge configurations. It includes a low-power shutdown and under-voltage protection circuit.

Application Fields

TPA3100D2RGZT is a high-power, high-performance, Class-D audio amplifier that can be used in various applications including automotive audio, stereo amplified sound systems, and audio speaker systems. The device provides a low-cost, low-distortion solution for applications where the output power required is higher than 25 Watts. The power supply can range from 2.25V to 5.5V.

Working Principle

The TPA3100D2RGZT amplifier is a fully integrated Class-D audio amplifier that operates with a MOSFET power output stage and an internal high-efficiency switching mode power supply. The device uses PWM (pulsewidth modulation) technique for producing an analog voltage output from a digital input. It works with an input voltage of up to 5 V and an output voltage of up to 32 V. The amplifier can product up to 25 watts of output power. The device can also switch between single-ended and bridge mode depending on the desired outcome.

The amplifier is powered by an input voltage between 2.25V and 5.5V. The input control signals are received in differential form and they are amplified by the internal amplifier. The amplified signals are then converted to PWM signals that are used to drive the output transistors. The output transistors are used to switch the power transistor on and off and regulate the output voltage. The amplifier has a low-power shutdown and under-voltage protection circuit that ensure the safety of the output transistors.
