PRODUCT BRIEF

PRELIMINARY DATA SHEET

AS14889

General Description

Key Features

The AS3510 combines high flexibility and outstanding

performance for analog audio front-end solutions.

On chip DCDC Converter

1.0 to 5.5V input voltage range

This codec-chip contains a high performance 18 bit digital

to analog converter. The dynamic range exceeds 95dB for

best audio quality, for multi media applications (audio

playback) within battery or line operated equipment.

4 On-chip high performance voltage regulators

Digital Supply, 2.9V

Analog Supply, 2.9V

Core Supply, 1.5 to 2.5V

USB Transceiver Supply, 3.2V

An additional audio power amplifier can directly drive

external headphones or small 4Ω speakers with a power of

up to half a watt. The power-up is click- and pop-less due to

a smooth start-up circuitry. The overall distortion level is

always below 0.02%.

18 Bit stereo DAC

Dynamic range >95 dB

THD < -85dB

De-emphasis for 32 kHz, 44.1 kHz and 48 kHz

Stereo power audio amplifier

The microphone input amplifier contains an automatic gain

control (AGC) with a dynamic range of 40dB to generate an

amplified and compressed signal for the ADC, which

provides 14 Bit resolution at 8kHz sampling-rate.

Max. 2x 0.5W @ 4Ω

Analog volume control –39dB to +3dB, 3dB steps

including mute)

Click- and pop-less startup and power down

Auxiliary inputs for additional audio sources

Furthermore all necessary power management is included

such as bandgap reference and four voltage regulators. The

two 2.9V regulators are used internally (analog and digital

supply), but can also be used for external purposes as well.

The third output is designed to supply the peripheral cells

and an external digital core, and is programmable from 1.5V

to 2.5V in 5 steps (default is 2.5V). They are all powered

through a DCDC-Converter, which can work down to a

voltage of 1V. So the whole chip can work from a single

battery cell.

Microphone input

14 Bit Σ∆−ADC , 8kHz sampling rate

Automatic gain control (AGC)

Low power consumption

Wide battery supply range 1.0V – 5.5V

Standard I2S interface

Audio sampling rates: 8, 11.025, 12, 16, 22.05, 24, 32,

44.1, and 48 kHz

The fourth regulator is only used for generating the supply

voltage for the analog USB 1.1 interface circuit. It is

supplied via the USB connector. The performance of the

regulators is excellent (noise, line- and load-regulation) and

allows the direct supply of sensitive analog circuits.

I2C control interface

USB 1.1 front-end

49 Pin BGA Package

Because of the internal supply and signal filtering only few

small external capacitors are required for de-coupling and

stabilising and lead to very low output noise.

Applications

Audio frontend for cellular phones

Stand alone MP3 player

CD and DVD player

PDAs

The current consumption is very low and makes the chip

ideally for battery powered devices.
