Product details
Overview
PCM3003E/2K from Texas Instruments is a 20-bit stereo audio codec IC integrating monolithic delta-sigma ADC and DAC with single-ended analog voltage I/O, 64× oversampling, hardware-controlled de-emphasis (32/44.1/48 kHz), independent ADC/DAC power-down, and SSOP-24 packaging - designed for cost-sensitive DSC applications requiring high-fidelity audio conversion at 3-V supply.
For engineers reviewing the PCM3003E/2K datasheet, PCM3003E/2K pinout, PCM3003E/2K application, or PCM3003E/2K equivalent, this page delivers verified electrical specs (THD+N = –86 dB, SNR = 94 dB), hardware-mode interface timing, SSOP-24 terminal mapping, and validated alternatives for portable digital still camera audio subsystems.
Technical Context
The PCM3003E/2K implements separate 20-bit delta-sigma modulators per channel: ADC uses 64× oversampling with digital decimation filter and antialiasing front-end; DAC employs 8× oversampling with interpolation filter, analog low-pass output stage, and programmable de-emphasis. All digital filtering operates on a system clock derived from 256/384/512 × fS.
Hardware control architecture defines its identity: mode selection (20BIT pin), de-emphasis (DEM0/DEM1), and independent power-down (PDAD/PDDA) are all Schmitt-trigger inputs with internal 100-kΩ pulldown resistors - eliminating software configuration overhead and ensuring deterministic startup behavior in embedded DSC systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 20-bit ADC and DAC - enables 94-dB dynamic range and supports high-fidelity audio capture/playback without external dithering. |
| THD+N | –86 dB at full scale - meets consumer-grade audio fidelity requirements for digital still cameras and portable recorders. |
| SNR | 94 dB (A-weighted, DAC) - ensures clean playback with minimal quantization noise in battery-powered devices. |
| Sampling Rate | 4–48 kHz - covers voice recording (4–8 kHz), telephony (8 kHz), CD-quality (44.1 kHz), and professional audio (48 kHz). |
| Supply Voltage | 2.7–3.6 V - compatible with single-cell Li-ion (3.0 V nominal) and regulated 3.3-V rails in compact imaging systems. |
| Power Dissipation | 72 mW typical (3 V, 44.1 kHz) - enables thermal management in space-constrained SSOP-24 layouts without heatsinking. |
| System Clock | 8.192–24.576 MHz (256/384/512 × fS) - allows flexible clock tree design using standard crystal oscillators or PLLs. |
Pinout & Package
PCM3003E/2K is housed in a 24-pin SSOP (Shrink Small Outline Package) with 0.64-mm lead pitch, optimized for compact PCB layouts in portable imaging equipment. Thermal resistance θJA = 100°C/W supports operation up to +85°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINL / VINR | ADC analog input (L/R) | Single-ended voltage inputs referenced to VCOM (0.5 × VCC); accept 1.8-Vp-p full-scale signal at 3-V supply. |
| VOUTL / VOUTR | DAC analog output (L/R) | Single-ended buffered outputs with integrated analog LPF; drive 10-kΩ load with –0.16-dB flatness to 20 kHz. |
| PDAD / PDDA | ADC/DAC power-down control | Active-low Schmitt-trigger inputs with internal 100-kΩ pulldown - enable independent low-power sleep modes per converter path. |
| DEM0 / DEM1 | De-emphasis select | Hardware-configured 2-bit code selecting 32/44.1/48 kHz de-emphasis or disabled - no firmware dependency required. |
| 20BIT | Data format control | Active-high Schmitt-trigger selects 20-bit right-justified (DAC) / left-justified (ADC) mode; defaults to 16-bit when low. |
| SYSCLK / LRCIN / BCKIN / DIN / DOUT | Digital audio interface | Four-wire synchronous serial interface supporting left/right-justified formats; timing compliant with TI's SBAS079A spec. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware-only configuration | Eliminates microcontroller firmware overhead for mode setup - ideal for resource-constrained DSC SoCs with fixed audio paths. |
| Independent ADC/DAC power-down | Reduces active current to 50 µA (power-down) vs. 24 mA (full operation) - extends battery life during standby or mono-record modes. |
| Integrated analog filters | On-chip antialiasing (ADC) and low-pass (DAC) filters remove need for external RC networks - saves board space and BOM cost. |
| De-emphasis support | Hardware-selectable 32/44.1/48 kHz pre-compensation matches legacy CD playback standards - improves perceived audio quality. |
| Single 3-V supply operation | Unifies analog (VCC1/VCC2) and digital (VDD) domains - simplifies power design and reduces DC/DC converter count in portable systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCM3002E/2K | Software-controlled (I²C register interface), supports four audio data formats including I²S; lacks hardware de-emphasis and 20BIT pin. | Requires MCU firmware integration; better suited for systems needing flexible format switching or digital loopback diagnostics. | Select PCM3002E/2K only if software configurability outweighs deterministic startup and reduced BOM count. |
| AK4552VN | 24-bit, 96-kHz capable, integrated headphone amp; requires dual 3.3-V/1.8-V supplies and external reference; no hardware de-emphasis. | Targets higher-resolution portable audio; incompatible pinout and power architecture - demands full PCB redesign. | Choose AK4552VN only when SNR > 100 dB and sample rates beyond 48 kHz are mandatory for next-gen product roadmap. |
Compared with PCM3002E/2K and AK4552VN, PCM3003E/2K delivers optimal balance of hardware simplicity, 20-bit fidelity at 48 kHz, and single-supply operation - making it the most direct fit for cost-sensitive DSC and voice recorder designs where firmware headroom is limited.

FAQ
What is the primary functional distinction between PCM3003E/2K and PCM3002E/2K?
The PCM3003E/2K uses hardware control (DEM0/DEM1, PDAD/PDDA, 20BIT pins) for de-emphasis, power-down, and data format selection, while PCM3002E/2K relies on software configuration via I²C registers. This makes PCM3003E/2K ideal for systems lacking firmware resources or requiring deterministic boot behavior - a key differentiator in DSC and voice recorder implementations.
Does PCM3003E/2K support I²S data format?
No, PCM3003E/2K supports only left-justified (ADC) and right-justified (DAC) formats, selectable via the 20BIT pin. Unlike PCM3002E/2K - which supports I²S and three additional formats via register programming - PCM3003E/2K's hardware-only interface excludes I²S to simplify layout and reduce MCU dependency.
What are the absolute maximum ratings for PCM3003E/2K supply voltages?
The PCM3003E/2K specifies absolute maximum supply voltages of –0.3 V to 6.5 V on VCC1, VCC2, and VDD pins. However, recommended operating conditions restrict VCC1/VCC2 and VDD to 2.7–3.6 V over –25°C to +85°C. Exceeding 3.6 V risks permanent damage, especially under transient conditions.
How does the PCM3003E/2K handle synchronization loss between LRCIN and SYSCLK?
When LRCIN phase jitter exceeds ±6 bit clocks per sample period, PCM3003E/2K halts internal DAC/ADC operation within 1/fS, forcing analog outputs to bipolar zero (0.5 × VCC) and digital outputs to zero codes. Resynchronization requires t(DACDLY2) = 32/fS and t(ADCDLY2) = 32/fS delays before valid data resumes - critical for robust USB audio or wireless link designs.
Can PCM3003E/2K operate at sampling rates below 32 kHz?
Yes, PCM3003E/2K supports sampling rates from 4 kHz to 48 kHz per datasheet SBAS079A. Operation below 32 kHz requires external system clock generation (e.g., 256 × fS), and performance curves confirm stable THD+N and SNR down to 4 kHz - enabling voice-band applications like intercoms and speech recognition modules.
