Product details
Overview
PCM3010DBR from Texas Instruments is a 24-bit stereo audio codec IC integrating delta-sigma ADC and DAC with single-ended analog I/O, 96-kHz max ADC sampling, 192-kHz max DAC sampling, ±0.05 dB pass-band ripple in ADC decimation filter, and THD+N of –95 dB (ADC) / –96 dB (DAC) at 44.1 kHz - used in PC audio and DVD recorder signal chains.
For engineers reviewing the PCM3010DBR datasheet, PCM3010DBR pinout, PCM3010DBR application, or PCM3010DBR equivalent, key selection criteria include dual-supply operation (5 V analog / 3.3 V digital), 24-pin SSOP package, 16-/24-bit audio data format support, de-emphasis at 32/44.1/48 kHz, and power-down mode for simultaneous ADC/DAC shutdown.
Technical Context
The PCM3010DBR implements fifth-order delta-sigma modulation in its ADC path with ×64 oversampling and a 1/128 or 1/64 decimation filter including an on-chip high-pass filter (0.84 Hz at 44.1 kHz). Its DAC uses an 8-level delta-sigma modulator with ×8 interpolation filtering and supports digital de-emphasis.
It accepts four serial audio interface formats (I²S, left-justified, right-justified), operates with system clocks from 128 fS to 768 fS, and features Schmitt-trigger digital inputs (5-V tolerant) with internal pulldown resistors on control pins FMT0/FMT1/DEMP0/DEMP1/PDWN/TEST.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit ADC and DAC - enables 102 dB dynamic range and high-fidelity audio digitization/reconstruction |
| ADC Sampling Rate | 16–96 kHz - supports CD-quality up to high-resolution consumer audio sampling |
| DAC Sampling Rate | 16–192 kHz - enables playback compatibility with high-sample-rate studio masters and SACD-derived content |
| THD+N (ADC) | –95 dB typical at 44.1 kHz - ensures low distortion in recording paths for professional-grade input fidelity |
| THD+N (DAC) | –96 dB typical at 44.1 kHz - delivers clean output for line-level audio reproduction without audible artifacts |
| Analog Supply | 5 V (VCC1/VCC2) - requires separate 5 V rails for ADC and DAC analog sections to minimize crosstalk |
| Digital Supply | 3.3 V (VDD) - compatible with modern low-voltage logic interfaces and reduces digital noise coupling |

Pinout & Package
Package: 24-pin SSOP (DB package), lead-free, 0.635 mm pitch, 8.2 mm × 3.9 mm body size.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINL / VINR | ADC analog inputs (L/R) | Single-ended 3 Vp-p voltage inputs referenced to VREF1/VREF2; require external 20 kΩ input impedance matching |
| VOUTL / VOUTR | DAC analog outputs (L/R) | Single-ended 3 Vp-p buffered outputs centered at VCOM (= 0.5 × VCC2); AC-coupled into ≥5 kΩ load |
| BCK / LRCK / DIN / DOUT | Audio data interface | I²S-compatible serial interface with bit clock, frame sync, and bidirectional data lines - supports 16-/24-bit MSB-first 2's complement |
| FMT0 / FMT1 | Data format select | Two-bit control for left-justified, I²S, or right-justified mode - sets protocol timing and word length alignment |
| PDWN | Power-down control | Active-low input that simultaneously disables ADC and DAC analog circuitry and forces outputs to VCOM |
| SCKI | System clock input | Accepts 128 fS to 768 fS clock (up to 50 MHz); auto-detects ratio to derive internal timing for 64× oversampling |
| VREF1 / VREF2 | ADC reference decoupling | Decoupling nodes for internal 0.5 × VCC1 reference - require 10 µF + 0.1 µF ceramic capacitors per pin |
| VCOM | DAC common voltage | Center voltage (0.5 × VCC2) for single-ended DAC outputs - must be decoupled with 10 µF capacitor |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AK4552VN | 24-bit, 96-kHz ADC/192-kHz DAC; 3.3 V analog/digital supply; no on-chip HPF or de-emphasis | Requires external de-emphasis circuitry and DC-blocking caps; better suited for portable battery-powered designs | Select when single-supply operation and lower quiescent current (<15 mA) outweigh loss of integrated features |
| CS4272-CQZ | 24-bit, 102-dB SNR; supports 192-kHz ADC/DAC; includes S/PDIF transmitter; 5 V analog / 3.3 V digital | Higher performance and digital interface flexibility but larger 48-pin QFP package and higher cost | Select when S/PDIF output or superior SNR (>102 dB) is required and board space permits larger footprint |
Compared with AK4552VN and CS4272-CQZ, the PCM3010DBR offers optimal balance of integrated analog features (HPF, de-emphasis, antialiasing/LPF), compact 24-pin SSOP packaging, and dual-supply isolation - making it ideal for cost-sensitive consumer audio where feature completeness and layout simplicity are prioritized over ultra-low power or digital interface expansion.

FAQ
What are the supported audio data formats for the PCM3010DBR?
The PCM3010DBR supports left-justified, I²S, and right-justified serial audio data formats with 16-bit or 24-bit word lengths. Format selection is controlled by the FMT0 and FMT1 pins, and all formats use MSB-first, two's complement representation. The PCM3010DBR does not support DSP or PCM modes outside these three configurations.
Does the PCM3010DBR support 192-kHz operation on both ADC and DAC?
No - the PCM3010DBR supports up to 96 kHz on the ADC and up to 192 kHz on the DAC. When a 192-kHz sampling rate is selected, the ADC is automatically disabled (DOUT remains LOW), and only the DAC remains active. This asymmetric capability is explicitly defined in the datasheet's system clock table and timing diagrams.
What is the function of the VCOM pin on the PCM3010DBR?
The VCOM pin on the PCM3010DBR provides the common-mode reference voltage (0.5 × VCC2) for the single-ended DAC outputs VOUTL and VOUTR. It must be decoupled to AGND2 using a 10 µF capacitor to stabilize the DAC output center point and prevent low-frequency drift or popping during power transitions.
How does the PCM3010DBR handle power-down sequencing?
The PCM3010DBR enters power-down mode when PDWN is driven LOW while maintaining synchronization between SCKI, BCK, and LRCK. Outputs VOUTL/VOUTR fade to VCOM within 2100/fS cycles; DOUT goes LOW immediately. Power dissipation drops to 1 mW. To resume operation, PDWN must be returned HIGH, triggering internal reset and reinitialization sequences before valid audio I/O resumes.
Can the PCM3010DBR operate with a single 5-V supply instead of separate analog and digital rails?
No - the PCM3010DBR requires three independent supplies: VCC1 and VCC2 (both 4.5–5.5 V) for ADC and DAC analog sections, and VDD (3.0–3.6 V) for digital logic. Interconnecting VCC1/VCC2 or raising VDD above 3.6 V violates absolute maximum ratings and risks latch-up or degraded THD+N performance per the datasheet's electrical characteristics table.
