SSM2604CPZ-REEL

Codecs Overview

The SSM2604 is a low-power stereo audio codec featuring two 24-bit analog-to-digital converters (ADC) and two 24-bit digital-to-analog converters (DAC). It supports sampling rates from 8 kHz to 96 kHz with an analog supply voltage range of 1.8 V to 3.6 V and a digital supply voltage range of 1.5 V to 3.6 V. The device achieves a DAC signal-to-noise ratio of 100 dB and an ADC signal-to-noise ratio of 90 dB at 48 kHz. Power consumption is 7 mW for stereo playback and 14 mW for record and playback operations at 1.8 V/1.5 V supplies. It operates within an industrial temperature range of −40°C to +85°C and is housed in a 20-lead, 4 mm × 4 mm LFCSP package.

Codecs Feature Summary

• Integrates stereo programmable gain amplifier line inputs with independent volume control for left and right channels.
• Supports multiple digital audio interface protocols including I2S, left-justified, right-justified, and DSP modes.
• Includes built-in digital high-pass filters for DC offset removal and de-emphasis filters for CD audio playback.

Codecs Applications
