Low Power Audio Codec

SSM2602

Preliminary Technical Data

FEATURES

GENERAL DESCRIPTION

Stereo, 24-bit analog-to-digital and digital-to-analog converters

DAC SNR: 98 dB (A-weighted), THD: −80 dB at 48 kHz, 3.3 V

ADC SNR: 90 dB (A-weighted), THD: −80 dB at 48 kHz, 3.3 V

Highly efficient headphone amplifier

Complete stereo/mono or microphone/line interface

Low power

7 mW stereo playback (1.8 V/1.8 V supplies)

14 mW record and playback (1.8 V/1.8 V supplies)

Low supply voltages

The SSM2602 is a low power, high quality stereo audio codec

for portable digital audio applications with stereo programmable

gain amplifier (PGA) line and monaural microphone inputs. It

features two 24-bit analog-to-digital converter (ADC) channels

and two 24-bit digital-to-audio (DAC) converter channels.

The SSM2602 can operate as a master or a slave. It offers

various master clock frequencies, including 12 MHz or 24 MHz

for USB devices; standard 256 f_Srates, such as 12.288 MHz and

24.576 MHz; and many common audio-sampling rates, such as

96 kHz, 88.2 kHz, 48 kHz, 44.1 kHz, 32 kHz, 16 kHz, and 8 kHz.

Analog: 1.8 V to 3.6 V

Digital core: 1.8 V to 3.6 V

The SSM2602 can operate at power supplies as low as 1.8 V for

the analog circuitry and 1.5 V for the digital circuitry. The

maximum voltage supply is 3.6 V for all supplies.

Digital I/O: 1.8 V/3.6 V

256 f_S/384 f_Sor USB master clock rate: 12 MHz, 24 MHz

Audio sample rates: 8 kHz,16 kHz, 32 kHz, 44.1 kHz, 48 kHz,

88.2 kHz, and 96 kHz

The SSM2602 software-programmable output options provide

the user with many application options, such as speaker driver,

headphone driver, or both. Its volume control functions provide

a large range of gain control of the audio signal.

28-lead, 5 mm × 5 mm LFCSP (QFN) package

APPLICATIONS

Mobile phones

MP3 players
