Key Features
- Integrated stereo 24-bit DAC and ADC supporting sample rates from 8 kHz to 96 kHz for high-fidelity portable audio applications
- On-chip headphone amplifier delivering 30 mW into 16 ohm loads, eliminating external audio amplifier components
- Synchronous I2S digital audio interface with I2C and SPI control bus, enabling direct connection to DSPs and microcontrollers without glue logic
Applications
The SSM2603CPZ-R2 is designed for portable consumer electronics and embedded audio applications requiring full-duplex stereo audio capture and playback in a compact footprint. It suits voice recognition front-end designs, Bluetooth audio modules, and USB audio adapters where low power consumption under 5 mW in idle mode extends battery life. Its integrated headphone driver and microphone bias circuit reduce external component count in handheld devices and IoT voice interface boards.

Frequently Asked Questions
What sample rates and bit depth does the SSM2603CPZ-R2 support for audio capture and playback?
The SSM2603CPZ-R2 supports sample rates from 8 kHz up to 96 kHz with 16-bit and 24-bit resolution for both ADC and DAC paths. The 96 kHz, 24-bit mode provides a dynamic range exceeding 90 dB, making it suitable for professional-grade audio recording in portable field recorders and studio interface prototypes.
How much output power does the SSM2603CPZ-R2 headphone amplifier deliver and into what impedance load?
The integrated headphone amplifier in the SSM2603CPZ-R2 delivers 30 mW of output power into a 16 ohm load, sufficient to drive standard headphones at comfortable listening levels without an external Class AB amplifier stage. This eliminates at least 2 external components — an op-amp and a coupling capacitor — reducing total BOM cost and PCB area in portable audio designs.
For a voice-command IoT device on a 3.3 V rail, why is the SSM2603CPZ-R2 preferred over a discrete ADC plus DAC combination?
The SSM2603CPZ-R2 integrates a stereo 24-bit ADC, a stereo 24-bit DAC, a microphone bias circuit, and a 30 mW headphone amplifier in a single 28-pin QFN package consuming as little as 5 mW in low-power mode. A discrete solution would require at minimum 4 ICs occupying over 40 mm2 of board area, whereas the SSM2603CPZ-R2 footprint is approximately 25 mm2, saving cost and enabling battery runtimes beyond 8 hours in a 500 mAh device.
