Product details
Overview
SSM2602CPZ-REEL7 from Analog Devices is a low-power, 24-bit stereo audio codec IC with integrated ADC/DAC, programmable gain amplifier (PGA), microphone bias, and headphone amplifier. It delivers 100 dB DAC SNR (A-weighted), 90 dB ADC SNR (A-weighted), and supports sampling rates up to 96 kHz at 1.5 V/1.8 V supplies - enabling high-fidelity audio in battery-constrained portable devices like MP3 players and mobile handsets.
For engineers reviewing the SSM2602CPZ-REEL7 datasheet, SSM2602CPZ-REEL7 pinout, SSM2602CPZ-REEL7 application, or SSM2602CPZ-REEL7 equivalent, key selection criteria include its dual-supply operation (1.5 V digital core / 1.8 V analog), I²C/SPI programmability, 28-pin LFCSP package, and support for USB-mode clocking (12/24 MHz MCLK) - all critical for compact, low-noise audio subsystem design.
Technical Context
The SSM2602CPZ-REEL7 integrates oversampling Σ-Δ ADCs and DACs with configurable digital filters (±0.04 dB passband ripple, −61 dB stopband attenuation), programmable high-pass filtering (3.7–21.6 Hz corner), and digital de-emphasis for 32/44.1/48 kHz sampling. Its digital core accepts master clock inputs from crystal (MCLK/XTI–XTO) or external sources with ≤50 ps jitter tolerance.
It operates as master or slave in I²S/PCM digital audio interface mode, supports BCLK/PBLRC/RECLRC timing per Tables 5–6, and features dual control interfaces: 2-wire I²C (up to 526 kHz) and 3-wire SPI (with CSB, SDIN, SCLK). Register-based configuration enables runtime adjustment of PGA gain (−34.5 dB to +33 dB), DAC volume (−73 dB to +6 dB), and ALC parameters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AK4556VN | 24-bit stereo codec with 94 dB DAC SNR, fixed 3.3 V supply only, no USB-mode clocking support | Lacks programmable mic boost and ALC; requires external regulators for multi-voltage systems | Choose AK4556VN only if system uses 3.3 V exclusively and does not require USB audio clock compatibility or advanced mic processing. |
| TLV320AIC3106IRGZR | 24-bit codec with 102 dB DAC SNR, integrated LDOs, and enhanced low-power modes (2.5 mW playback) | Includes stereo Class-D speaker driver; supports TDM interface; larger 32-pin QFN package | Choose TLV320AIC3106IRGZR when speaker drive capability, ultra-low power, or TDM bus integration is required - but expect higher cost and layout complexity. |
Compared with AK4556VN and TLV320AIC3106IRGZR, the SSM2602CPZ-REEL7 offers balanced performance across power efficiency (7 mW), feature set (ALC, USB clocking, dual supply), and package size (5 mm × 5 mm LFCSP), making it optimal for space-constrained portable designs needing flexible audio I/O without over-engineering.

FAQ
What is the maximum sampling rate supported by the SSM2602CPZ-REEL7?
The SSM2602CPZ-REEL7 supports audio sampling rates from 8 kHz up to 96 kHz, including standard rates such as 44.1 kHz (CD), 48 kHz (DAT), and 88.2 kHz. This full range is achievable in both master and slave digital audio interface modes, with corresponding digital filter characteristics optimized per rate - ensuring accurate frequency response and minimal aliasing in the SSM2602CPZ-REEL7.
Does the SSM2602CPZ-REEL7 support USB audio class clocking?
Yes, the SSM2602CPZ-REEL7 supports USB audio class clocking through its MCLK/XTI input, accepting 12 MHz or 24 MHz master clock frequencies commonly used in USB audio devices. In USB mode, it uses 250/272× oversampling and maintains full functionality including ADC/DAC conversion, ALC, and register control - making the SSM2602CPZ-REEL7 suitable for USB-powered headsets and dongles.
Can the SSM2602CPZ-REEL7 operate from a single 1.8 V supply?
No - the SSM2602CPZ-REEL7 requires separate supply domains: analog circuitry (AVDD, HPVDD) operates from 1.8 V to 3.6 V, digital core (DCVDD) from 1.5 V to 3.6 V, and digital I/O (DBVDD) from 1.8 V to 3.6 V. While 1.8 V may be applied to AVDD and DBVDD, DCVDD must be ≥1.5 V; using 1.8 V across all rails is valid and commonly implemented to simplify power design in the SSM2602CPZ-REEL7.
What headphone load can the SSM2602CPZ-REEL7 drive?
The SSM2602CPZ-REEL7 headphone amplifier delivers 30 mW into a 32 Ω load and 60 mW into a 16 Ω load at AVDD = 3.3 V. Performance scales with supply voltage - at 1.8 V, output power decreases proportionally but remains sufficient for low-impedance earbuds. The LHPOUT/RHPOUT pins require AC-coupling capacitors and are specified for single-ended, capacitor-coupled headphone connections in the SSM2602CPZ-REEL7.
How is microphone input gain configured on the SSM2602CPZ-REEL7?
Microphone input gain on the SSM2602CPZ-REEL7 is configured in two stages: first-stage gain is set by an external resistor (REXT) in series with MICIN, yielding 0–14 dB; second-stage boost (0/20/40 dB) is controlled by MICBOOST and MICBOOST2 bits (Register R4). Total gain is sum of both stages, and mute is enabled via MUTEMIC bit - all programmable in real time via I²C or SPI interface in the SSM2602CPZ-REEL7.
