Portable Navigation Devices

4 Ω or 1.7 W Into 8 Ω)

• Mono Headphone Driver

1.3 Description

• Two Single-Ended Inputs With Output Mixing

and Level Control

The TAS2521 is a low power digital input speaker

amp with support for 24-bit digital I2S data mono

playback.

• Embedded Power-on-Reset

• Integrated LDO

• Built-in Digital Audio Processing Blocks With

User-Programmable Biquad Filters

In addition to driving a speaker amp upto 4-Ω, the

device also features a mono headphone driver and a

fully programmable miniDSP for signal processing.

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 fully programmable miniDSP can support

several functions such equalization for audio, multi-

band DRC, tone generation and several other user

defined 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 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.

• Integrated PLL Used for Programmable Digital

Audio Processor

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

TDM Audio Interfaces

• I²C 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)
