SSM2604

低功耗音频编解码器 Low Power Audio Codec

Product Details

The 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. It features two 24-bit analog-to-digital converter ADC channels and two 24-bit digital-to-analog DAC converter channels.

The SSM2604 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 sam-pling 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 SSM2604 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 SSM2604 is specified over the industrial temperature range of −40°C to +85°C. It is available in a 20-lead, 4 mm × 4 mm lead frame chip scale package LFCSP.
