Texas Instruments TPA2032D1 2.75-W Mono Class-D Audio Amplifier with 2 V/V Fixed Gain (TPA2032) TPA2032D1YZFT

The TPA2032D1 is a 2.75-W Mono Class-D audio amplifier featuring a fixed gain of 2 V/V (6 dB). It operates efficiently with a power supply voltage range of 2.5 V to 5.5 V and is designed for applications requiring high efficiency and minimal heat generation. The amplifier achieves up to 88% efficiency at 400 mW output power into an 8-ohm load. It has a low quiescent current of 3.0 mA and a shutdown current of 0.5 mA, making it suitable for battery-powered devices. The device is housed in a wafer chip scale package (WCSP) measuring approximately 1.5 mm x 1.5 mm, which allows for a compact design. It includes built-in thermal and short-circuit protection, ensuring reliability in various operating conditions. The TPA2032D1 also features a fast startup time of 3.2 ms and a low noise floor of 27 mV, A-weighted, which is beneficial for audio applications. With a power supply rejection ratio (PSRR) of -75 dB and a common mode rejection ratio (CMRR) of -69 dB, it is designed to minimize interference and improve audio quality. This amplifier is ideal for use in wireless handsets, PDAs, and other mobile devices.
