PCM3003E - Low-Power Stereo Audio Codec | Texas Instruments
MPN: PCM3003E ✓ نشطPCM3003E نظرة عامة
An audio codec is an integrated interface that converts between analog audio signals and digital PCM data. The PCM3003E combines stereo analog-to-digital and digital-to-analog conversion functions in one IC, making it suitable for compact consumer audio equipment where component count, power consumption, and board area are important. Its digital audio interface and analog signal path support equipment such as consumer audio systems, portable products, and compact multimedia devices.
The PCM3003E offers selectable 16-bit or 20-bit operation, providing flexibility for designs that balance conversion resolution against system data rate and storage requirements. Its line output includes hardware control, allowing the output stage to be managed according to the product architecture. A single-ended analog interface can simplify PCB routing, although grounding and signal-return design remain important for low-noise performance.
The codec is manufactured using an advanced CMOS process and is intended for cost-sensitive consumer applications that require good audio performance without a high-complexity audio interface. The 24-pin SSOP package supports conventional surface-mount assembly and is compatible with automated production processes. System designers should follow the manufacturer pin-description table and recommended application circuit when assigning PCB tracks.
Typical PCM3003E applications include stereo audio playback and capture, consumer media equipment, compact sound systems, and embedded audio products. The 2.7 V to 3.6 V operating range supports low-voltage digital platforms, while the -25 °C to +85 °C temperature range covers industrial environments. External decoupling, controlled analog grounding, and careful clock routing should be treated as core parts of the analog design.
This product page combines manufacturer specifications, packaging information, application guidance, and engineering comparisons. It also distinguishes the PCM3003E from identified family variants and highlights the design checks that matter when integrating a low-power stereo codec into a mixed-signal PCB.

التطبيقات النموذجية
PCM3003E مناسب لـ 6 التطبيقs: Stereo Consumer Audio System, Portable Media Player, Digital Recording and Playback, Industrial Audio Control Panel, Multimedia Speaker Interface, Embedded Audio Sensor Hub.
Stereo Consumer Audio System
PCM3003E is well suited to compact stereo consumer equipment because it combines 16-bit or 20-bit analog-to-digital and digital-to-analog conversion in one low-power IC. The single-ended stereo analog I/O simplifies system partitioning, while the 24-pin SSOP package limits board area. A typical design places the codec between a digital audio processor and line-level input or output circuitry. The 2.7 V to 3.6 V operating range accommodates low-voltage system rails, although the power architecture must preserve analog performance.

Portable Media Player
The PCM3003E supports portable media applications requiring stereo recording and playback from a compact, low-voltage architecture. Its selectable 16-bit or 20-bit operation lets the system designer match interface data rate and storage requirements without changing the analog signal path. Single-ended inputs and outputs can reduce external component count, while the low-power codec architecture supports energy-conscious consumer products. Layout should isolate clock and data paths from microphone or line-level analog inputs to prevent digital coupling.
موصى به
Digital Recording and Playback
PCM3003E can serve as the central conversion device in a two-channel digital audio recorder. The stereo 16-bit or 20-bit converters support direct connection to digital audio processing logic, while single-ended analog inputs simplify source selection and gain staging. Hardware line-output control provides a controllable route for line-level playback. Designers should use short analog traces, quiet reference grounding, and the manufacturer’s recommended capacitor placement to preserve signal quality during simultaneous capture and playback.
موصى به
Industrial Audio Control Panel
The PCM3003E’s -25 °C to +85 °C operating range supports industrial audio-control equipment deployed within moderate environmental conditions. It can convert stereo analog sources for digital processing and generate stereo audio outputs for monitoring or announcement functions. The low-power codec and 24-pin SSOP package are useful in compact control electronics. System designers should verify enclosure temperature, grounding topology, and conducted-noise immunity because the codec’s environmental rating does not replace overall enclosure and power-supply qualification.
موصى به
Multimedia Speaker Interface
PCM3003E is appropriate for multimedia products that need integrated stereo playback and capture rather than separate converter ICs. Digital audio data from a processor enters the codec, and the single-ended analog outputs drive a line-level amplifier stage. The 2.7 V to 3.6 V operating range supports common low-voltage systems, while the 24-pin SSOP package simplifies cost-oriented construction. Power-supply sequencing and analog settling should be checked when the codec shares a board with switching regulators or high-speed processors.
موصى به
Embedded Audio Sensor Hub
PCM3003E can support compact embedded audio-hub designs that accept or produce stereo analog signals alongside digital sensor processing. Its low-power 2.7 V to 3.6 V operating range is useful for distributed audio nodes, while the stereo converter capability handles two synchronized channels. A practical implementation uses controlled analog grounding, short input traces, and separate digital return management to prevent codec inputs from coupling to processor switching activity. Firmware must also match the configured data format, word length, and clock configuration.

ملاحظات التصميم
Separate the analog and digital regions of the PCB while providing a controlled ground connection beneath the codec. Place the required input, output, and bypass capacitors adjacent to their associated pins, and route serial data and clock signals away from the single-ended audio inputs. Keep the analog traces short and avoid routing them beneath digital clocks, switching-regulator nodes, or high-speed memory buses.
Design a low-noise supply path for the 2.7 V to 3.6 V analog operating range. Follow the Texas Instruments PCM3003 recommended application circuit for bypass capacitance, component placement, and power sequencing. If the codec shares a rail with switching circuitry, evaluate filtering or a dedicated low-noise rail because regulator ripple and ground bounce can influence the analog signal path.
Do not treat PCM3003E, PCM3003E/2K, and PCM3003E/T1 as automatically interchangeable solely because they share the family name. Confirm the exact orderable suffix, temperature range, reel configuration, and manufacturer ordering information. For any cross-brand replacement, also verify pin-by-pin assignment, clock and data timing, supply pins, analog output topology, and package geometry before reusing a PCB.
Use the manufacturer timing diagrams to establish clock and serial-data timing at the codec. Avoid long parallel bus routing where a serial audio interface is used, and terminate or control clock edges to limit ringing. Keep switching-node copper and high-current return paths away from the analog input and output region, particularly when the codec supports microphone-level or other low-amplitude signals.
معلومات الامتثال
PCM3003E is a consumer stereo audio codec, so AEC-Q100 qualification does not apply. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation from the current manufacturer product documentation.
