PCM1820IRTER

PCM1820IRTER is a Texas Instruments part—the PCM1820 stereo audio CODEC device used for high-quality PCM audio front-ends. It typically provides digital-to-analog and/or analog-to-digital conversion for two channels and interfaces with a host processor via standard digital formats (such as I2S or left-justified data). It’s aimed at consumer and professional audio applications where compact, integrated audio front-ends are beneficial.
Key points:
- Stereo PCM audio codec/digital interface
- Standard digital interfaces (e.g., I2S)
- Used in audio playback/recording front-ends, receivers, DAC/ADC applications
The suffix IRTER relates to packaging (e.g., tape-and-reel/reel-packaged parts) and RoHS-compliant packaging. For exact capabilities, performance specs, pinout, and packaging details, consult the TI PCM1820 datasheet.

PCM1820IRTER is a stereo 24-bit delta-sigma DAC. Typical features include:
- Up to 192 kHz sampling rate
- Differential current-output DAC requiring external I/V conversion and reconstruction filters
- Flexible digital interface: I2S, left-justified, right-justified; supports master/slave clock modes
- High dynamic range with low distortion for clean audio
- Optional reference configuration and soft-mute/pop-free power-down
- Analog outputs suitable for external op-amp stages or direct line/headphone paths
- Low power operation and RoHS-compliant package (IRTER)
Note: exact specs may vary by revision; consult the official datasheet for precise electrical characteristics and recommended application circuitry.

Pin count: 28 pins (28-pin package; “TER” indicates Tape & Reel variant).
Function: Dual-channel stereo digital-to-analog converter (DAC) with I2S/serial audio input. Converts digital audio to analog left and right outputs; requires power, ground, and reference pins.

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and related electronic components.

PCM1820IRTER is a high-performance stereo ADC. Typical application areas include:
- Consumer electronics: audio interfaces, TVs, Blu-ray players, game consoles, DAC/amp combos
- Professional audio: mixers, digital recorders, studio interfaces, DSP-enabled monitors
- Telecommunication and conferencing: VoIP endpoints, conference phones, room systems
- Automotive: in-car infotainment and multimedia audio front-ends
- Instrumentation and measurement: audio test rigs, acoustic measurement equipment
- Portable multimedia devices requiring high-resolution stereo capture
Note: Uses depend on your system’s I/O and power requirements.
