Description

The TAS2505 is a low power digital input speaker amp with support for 24-bit digital I2S data mono playback.

In addition to driving a speaker amp up to 4-Ω, the device also features a mono headphone driver and a programmable digital-signal processing block. The digital audio data format is programmable to work with popular audio standard protocols (I2S, left/right-justified) in master, slave, DSP and TDM modes. The programmable digital-signal processing block can support Bass boost, treble, or EQ functions. An on-chip PLL provides the high-speed clock needed by the digital signal-processing block. The volume level can be controlled by register control. The audio functions are controlled using the I2C ™ serial bus or SPI bus.

The device includes an on-board LDO that runs off the speaker power supply to handle all internal device analog and digital power needs. The included POR as power-on-reset circuit reliably resets the device into its default state so no external reset is required at normal usage; however, the device does have a reset pin for more complex system initialization needs. The device also includes two analog inputs for mixing and muxing in both speaker and headphone analog paths.
