Product details
Overview
PCM3000E/2K from Texas Instruments is an 18-bit stereo audio codec integrating monolithic delta-sigma ADC and DAC with single-ended analog voltage inputs/outputs, 64× oversampling ADC filter, 8× oversampling DAC filter, and digital de-emphasis - used in DSP-based car stereo systems requiring high-fidelity audio conversion at 44.1 kHz sampling rate.
For engineers reviewing the PCM3000E/2K datasheet, PCM3000E/2K pinout, PCM3000E/2K application, or PCM3000E/2K equivalent, key selection criteria include THD+N (–88 dB), SNR (94 dB), system clock support (256/384/512 fS), 28-pin SSOP package, and programmable serial interface for data format control.
Technical Context
The PCM3000E/2K implements dual delta-sigma modulation architecture: left/right ADCs use 64× oversampling with decimation and digital high-pass filtering, while DACs employ 8× oversampling interpolation, digital attenuation (256 steps), soft mute, and infinite zero detection. All digital filters operate on a derived 256 fS internal clock regardless of input SYSCLK (256/384/512 fS).
It supports seven audio data formats (I²S, left/right-justified, DSP-frame) via three-wire serial interface (MC/MD/ML pins); accepts TTL-level digital I/O; features separate analog/digital power domains (VCC1/VCC2/VDD); and includes internal power-on reset requiring 1024 system clock cycles for initialization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCM3001E/2K | Pin-programmable format selection (FMT0–FMT2) vs. serial interface; identical ADC/DAC specs and package | No microcontroller required for format setup; fixed configuration after power-up | Select PCM3001E/2K when firmware simplicity and deterministic boot behavior are prioritized over runtime reconfiguration |
| AK4552VN | 24-bit resolution, lower THD+N (–95 dB), requires ±5 V analog supplies vs. single 5 V | Better dynamic range for professional recording; incompatible supply scheme increases BOM cost | Select AK4552VN only when >94 dB SNR is mandatory and dual-supply design is acceptable |
Compared with PCM3000E/2K, PCM3001E/2K eliminates serial programming overhead but sacrifices runtime format flexibility, while AK4552VN delivers higher resolution at the cost of supply complexity and reduced pin compatibility - making PCM3000E/2K optimal for cost-sensitive, microcontroller-based consumer audio with configurable I/O timing.

FAQ
What is the maximum sampling rate supported by the PCM3000E/2K?
The PCM3000E/2K supports sampling rates from 4 kHz up to 48 kHz, with typical operation at 44.1 kHz for CD-quality audio and 48 kHz for DAT and professional audio applications. The device's digital filters and modulators are optimized for this range, and all published AC performance metrics (THD+N, SNR, dynamic range) are specified at 44.1 kHz with 384 fS system clock.
Does the PCM3000E/2K require external antialiasing or reconstruction filters?
No, the PCM3000E/2K integrates both functions: its ADC includes a switched-capacitor antialiasing filter with 170 kHz –3 dB cutoff (using external 470 pF capacitors), and its DAC incorporates an analog low-pass filter with –0.16 dB response at 20 kHz. These on-chip filters eliminate the need for external passive RC or active filter stages in most consumer implementations.
How is the PCM3000E/2K configured for different audio data formats?
The PCM3000E/2K uses a three-wire serial interface (MC, MD, ML pins) to program register 3 for one of seven supported formats - including I²S, left/right-justified, and DSP-frame - enabling runtime reconfiguration. This differs from the pin-strapped PCM3001E/2K, making PCM3000E/2K ideal for systems requiring dynamic format switching under MCU control.
What are the power supply requirements for the PCM3000E/2K?
The PCM3000E/2K operates from a single 5 V supply (4.5–5.5 V) applied to VCC1 (ADC analog), VCC2 (DAC analog), and VDD (digital). It draws 32–50 mA total supply current and dissipates 160–250 mW. No negative or split supplies are needed, simplifying power design for battery-powered or USB-powered audio devices.
Can the PCM3000E/2K perform digital loopback for self-test?
Yes, the PCM3000E/2K supports internal digital loopback mode, routing ADC digital output directly to DAC input without external signal paths. This feature is enabled via serial interface register control and is used for production test, latency verification, and real-time diagnostic validation - ensuring signal integrity without requiring physical I/O connections.
