Low Power Audio Codec Data Sheet SSM2603 FEATURES GENERAL DESCRIPTION Stereo, 24-bit analog-to-digital and digital-to-analog converters
The SSM2603 is a low power, high quality stereo audio codec
DAC SNR: 100 dB (A-weighted), THD: −80 dB at 48 kHz, 3.3 V
for portable digital audio applications with one set of stereo
ADC SNR: 90 dB (A-weighted), THD: −80 dB at 48 kHz, 3.3 V
programmable gain amplifier (PGA) line inputs and one
Highly efficient headphone amplifier
monaural microphone input. It features two 24-bit analog-to-
Stereo line input and monaural microphone input
digital converter (ADC) channels and two 24-bit digital-to-
Low power
