TPA2005D1DGN Description

Short technical summary and product information.

The TPA2005D1DGN from Texas Instruments is a 1.4-W, mono, filter-free Class-D audio power amplifier. It is designed for applications requiring high efficiency and low heat generation, offering up to 84% efficiency.

This amplifier accepts analog input and operates with a power stage supply voltage ranging from 2.5V to 5.5V. It delivers 1.4W into an 8-ohm load from a 5V supply with a typical THD+N of 0.2% at 1kHz. The device features a low quiescent current of 2.8mA and a shutdown current of 0.5μA, contributing to maximum battery life.

The TPA2005D1DGN utilizes an optimized PWM output stage that eliminates the need for an external LC output filter. It has an internally generated 250-kHz switching frequency and offers improved PSRR of -71 dB at 217 Hz. The amplifier is capable of driving an 8-ohm speaker from 2.5V to 5.5V and a 4-ohm speaker from 2.5V to 4.2V.

Available in space-saving packages such as HVSSOP, VSON, QFN, MicroStar Junior BGA, and MSOP PowerPAD, the TPA2005D1DGN is suitable for compact designs. Its operating temperature range is -40°C to 85°C.
