TPA6205A1DGNG4 is an integrated, low-power, stereo, digital amplifier with a maximum output power of 1.85W/channel into 4-Ω load from 3.2V supply. The device integrates two separate amplifiers into one package, with the ability to be configured for single-channel, mono, stereo and mono-bridge applications. It is designed for personal audio devices, including portable systems, such as MP3, portable DVD and other digital audio systems. The device features an integrated power stage, current-feedback design, differential inputs and supports variable gain settings.

The TPA6205A1DGNG4 is a low power amplifier with a maximum output power of 1.85W/channel into 4-Ω load from 3.2V supply. The device combines the most important characteristics of a modern amplifier into one system, high performance, low distortion, low power consumption and low cost. Its very low distortion (typ 0.02%) low power consumption, high efficiency and small physical size make it a perfect choice for personal audio applications.

This amplifier operates from a wide supply range from 2.5V to 5.25V and maximum output power of 1.85W/channel into 4-Ω speaker. It also features a low total harmonic distortion (THD) of 0.02% for 2.0V/4-Ω and 0.07% for 1.5V/4-Ω. The amplifier supports a wide range of gains, ranging from 0dB to 20dB whilst maintaining low distortion.

The device also features a Standby/Shutdown mode to reduce system power consumption. When the amplifier is in the standby mode, the device is fully operational but the output power is reduced. The Shutdown mode completely disconnects the amplifier from the power supply and should be used when an extended period of shutoff is needed. This reduces the consumption to 0.1µA.

The device has an integrated power stage that is controlled by a current-feedback differential input for improved stability, performance and dynamic range. This improve the performance of the amplifier, making it more suitable for demanding applications such as MP3 and portable DVD systems.

The TPA6205A1DGNG4 audio amplifier is suitable for a wide range of applications including automotive audio, digital helper and microcontrollers, portable speakers, MP3 players, portable DVD players, systems with medium power requirements and systems that operate in a wide range of temperature and humidity conditions. The device is characterized for operation over the extended temperature range from - 40°C to +85°C.

In summary, the TPA6205A1DGNG4 amplifier is an efficient, low-power audio amplifier with low THD and high output power. It offers great performance in a very small package and is suitable for a wide range of applications. It is ideal for applications such as portable DVD, MP3 and other digital audio systems.
