1.3 Description

The TAS2505 is a low power digital input speaker

amp with support for 24-bit digital I2S data mono

playback.

• Programmable Digital Audio Processing Blocks

for Bass Boost, Treble, EQ With up to Six

Biquads for Playback

In addition to driving a speaker amp upto 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-resetcircuit reliably resets

the device into its default state so no external reset is

required at normal usage; however, the device does

• Integrated PLL Used for Programmable Digital

Audio Processing Blocks

• I²S, Left-Justified, Right-Justified, DSP, and

TDM Audio Interfaces

• I²C Control and SPI control with auto-increment

• Full Power-Down Control

• Power Supplies:

– Analog: 1.5 V–1.95 V

– Digital Core: 1.65 V–1.95 V

– Digital I/O: 1.1 V–3.6 V

– Class-D: 2.7 V–5.5 V (SPKVDD ≥ AVDD)

• 24-Pin QFN Package (4mm × 4mm)

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.
