The SSM2603 is a low power, high quality stereo audio codec
for portable digital audio applications with one set of stereo
programmable gain amplifier (PGA) line inputs and one
monaural microphone input. It features two 24-bit analog-to-
digital converter (ADC) channels and two 24-bit digital-to-
analog (DAC) converter channels.
The SSM2603 can operate as a master or a slave. It supports
various master clock frequencies, including 12 MHz or 24 MHz
for USB devices; standard 256 fS or 384 fS based rates, 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, 24
kHz, 22.05 kHz, 16 kHz, 12 kHz, 11.025 kHz, and 8 kHz.
The SSM2603 can operate at power supplies as low as 1.8 V for
the analog circuitry and as low as 1.5 V for the digital circuitry.
The maximum voltage supply is 3.6 V for all supplies.
The SSM2603 software-programmable stereo output options
provide the user with many application possibilities. Its volume
control functions provide a large range of gain control of the
audio signal.
The SSM2603 is specified over the industrial temperature range
of −40°C to +85°C. It is available in a 28-lead, 5 mm × 5 mm
lead frame chip scale package (LFCSP).
