Product details
Overview
SSM2603CPZ-R2 from Analog Devices is a low-power, 24-bit stereo audio codec IC for portable digital audio systems, integrating dual Σ-Δ ADCs (90 dB SNR A-weighted) and dual Σ-Δ DACs (100 dB SNR A-weighted), a programmable-gain microphone input, stereo line inputs, and a 30 mW headphone amplifier driving 32 Ω loads - deployed in mobile phones and MP3 players.
For engineers reviewing the SSM2603CPZ-R2 datasheet, SSM2603CPZ-R2 pinout, SSM2603CPZ-R2 application, or SSM2603CPZ-R2 equivalent, key selection considerations include its 1.5 V–3.6 V dual-supply operation, I²C control interface, 28-pin 5 mm × 5 mm LFCSP package, and support for 8–96 kHz sampling rates with hardware mute and ALC functionality.
Technical Context
The SSM2603CPZ-R2 implements oversampling Σ-Δ architecture for both ADC and DAC paths, with configurable 256×/384× oversampling in normal mode and 250×/272× in USB mode. It supports master or slave audio interface operation via BCLK, PBLRC/RECLRC, and PBDAT/RECDAT signals.
Digital core clocking is flexible: accepts external MCLK (8–18.5 MHz) or crystal (MCLK/XTI + XTO), with optional CLKDIV2 division and buffered CLKOUT output. Internal high-pass filtering (3.7–21.6 Hz corner) and digital de-emphasis (for 32/44.1/48 kHz) are software-configurable per register settings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DAC SNR (A-weighted) | 100 dB at 48 kHz, 3.3 V - enables high-fidelity playback with minimal audible noise floor in portable audio outputs |
| ADC SNR (A-weighted) | 90 dB at 48 kHz, 3.3 V - supports clean recording of voice and music without quantization distortion |
| Headphone Output Power | 30 mW into 32 Ω - drives standard consumer headphones directly without external amplification |
| Supply Voltage Range | Analog: 1.8–3.6 V; Digital Core: 1.5–3.6 V - allows single-cell Li-ion or dual-supply battery architectures |
| Sampling Rates | 8–96 kHz - covers all standard audio formats including CD (44.1 kHz), DVD (48 kHz), and HD audio (88.2/96 kHz) |
| Power Consumption | 7 mW stereo playback (1.8 V/1.5 V) - extends battery life in always-on audio subsystems |
| Interface Protocol | I²C control + I²S/PCM digital audio - simplifies integration with ARM Cortex-M or DSP host processors |
Pinout & Package
SSM2603CPZ-R2 is housed in a 28-lead, 5 mm × 5 mm lead frame chip scale package (LFCSP) with exposed thermal pad connected to PCB ground. Pin functions are validated per Analog Devices Rev. D datasheet Figure 6 and Table 9.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MCLK/XTI | Master Clock Input / Crystal Input | Accepts external clock (8–18.5 MHz) or crystal oscillator signal to synchronize ADC/DAC sampling |
| PBDAT / RECDAT | DAC Data Input / ADC Data Output | Serial audio data lines for I²S/PCM interface - bidirectional timing referenced to BCLK |
| LHPOUT / RHPOUT | Left/Right Headphone Output | Capable of 30 mW into 32 Ω; DC-coupled to VMID reference for rail-to-rail swing |
| MICIN / MICBIAS | Microphone Input / Bias Voltage Source | MICIN accepts single-ended electret mic; MICBIAS provides 0.75 × AVDD bias current up to 3 mA |
| CSB / SDIN / SCLK | I²C Address / Data / Clock | 2-wire serial interface for register configuration - supports multiple codecs on same bus via CSB pin |
Key Features
| Feature | Design Value |
|---|---|
| Programmable PGA Gain | −34.5 dB to +33 dB in 1.5 dB steps - adapts to varying mic sensitivity and line-level sources without external gain stages |
| Hardware MUTE Pin | Active-low asynchronous mute (Pin 25) - forces DAC outputs to VMID for glitch-free audio muting during power transitions |
| Automatic Level Control (ALC) | Configurable attack/decay timing and noise gate threshold - prevents ADC clipping on loud transients while suppressing hiss during silence |
| Digital De-Emphasis | On-chip FIR filter activated for 32/44.1/48 kHz sampling - corrects pre-emphasized CD/DVD audio without host CPU intervention |
| Low-Voltage Operation | 1.5 V digital core supply - enables direct connection to ultra-low-power SoC domains, reducing system-level voltage conversion losses |
Applications
| Mobile Handset Audio Subsystem | Portable Media Player Playback |
|---|---|

Use Value: Integrated 28-pin LFCSP eliminates need for separate USB audio controller IC and external PLL, reducing adapter PCB area by 40%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AK4556EN | Higher 102 dB DAC SNR but requires 2.5–3.6 V analog supply; no integrated mic bias; 32-pin QFN | Better SNR for studio-grade playback, but lacks ALC and sidetone - unsuitable for full-duplex voice | Select when ultimate DAC fidelity is prioritized over mic processing and power efficiency |
| TLV320AIC3106IRSBT | Lower 94 dB DAC SNR; integrated LDOs; SPI/I²C dual interface; 32-pin WQFN | Supports wider supply range (1.65–3.6 V); includes charge pump for higher headphone voltage swing | Choose when system lacks dedicated low-noise LDOs or requires >30 mW headphone drive into 16 Ω |
Compared with AK4556EN and TLV320AIC3106IRSBT, the SSM2603CPZ-R2 delivers optimal balance of low-power operation (7 mW playback), integrated mic bias and ALC, and compact 28-pin LFCSP - making it uniquely suited for space-constrained, battery-sensitive portable voice/audio devices where full-duplex capability is mandatory.

FAQ
What is the maximum sampling rate supported by the SSM2603CPZ-R2?
The SSM2603CPZ-R2 supports audio sampling rates up to 96 kHz in both ADC and DAC paths, with verified performance at 88.2 kHz and 96 kHz per the Rev. D datasheet Table 1. This enables high-resolution audio playback and recording compatible with professional and consumer-grade media formats.
Does the SSM2603CPZ-R2 include an integrated microphone bias voltage source?
Yes, the SSM2603CPZ-R2 includes an integrated MICBIAS output (Pin 21) that delivers 0.75 × AVDD bias voltage with up to 3 mA sourcing capability - sufficient to power standard electret condenser microphones without external bias circuitry.
Can the SSM2603CPZ-R2 operate from a single 1.8 V supply?
No - the SSM2603CPZ-R2 requires three independent supply domains: analog (AVDD = 1.8–3.6 V), digital core (DCVDD = 1.5–3.6 V), and digital I/O (DBVDD = 1.8–3.6 V). All three must be present; however, they may share the same 1.8 V rail if decoupled appropriately per datasheet recommendations.
What is the function of the VMID pin on the SSM2603CPZ-R2?
The VMID pin (Pin 20) provides a mid-rail voltage reference (AVDD/2) used internally for AC-coupled analog signal biasing. It must be decoupled with a minimum 4.7 µF capacitor to ground to stabilize the reference and ensure proper ADC/DAC common-mode operation.
Is the SSM2603CPZ-R2 pin-compatible with other members of the SSM26xx family?
No - the SSM2603CPZ-R2 is not pin-compatible with SSM2602 or SSM2604. While sharing functional similarities, each variant has distinct pin assignments (e.g., SSM2604 adds GPIO pins and removes CLKOUT), confirmed by comparing Rev. D datasheet pin configurations and ordering guides.
