概述

Description

PCM1820IRTER is a variant of the PCM1820 family, a high‑quality stereo digital‑to‑analog converter (DAC) from TI. It converts a digital PCM audio stream into two analog outputs for stereo playback. Typical use is in DAC boards, audio receivers, CD players, and other audio gear.
Key points (to verify with the exact datasheet for your part):
- 2‑channel DAC with digital input (I2S/left‑justified common in TI devices)
- High resolution (commonly 24‑bit) and support for high sampling rates
- Differential current outputs requiring an external I/V stage and reconstruction filter
- Low distortion, low noise, and suitable for consumer or professional audio paths
Suffix “IRTER” usually denotes packaging/quantity/temperature variant in TI’s naming scheme, not the electrical function. For precise specs, pinout, and application guidance, consult the exact datasheet for the PCM1820IRTER variant from TI or your supplier.
If you can share the manufacturer or a link, I’ll tailor the intro to the exact device.

Features

PCM1820IRTER is a high‑fidelity 24‑bit stereo DAC (delta‑sigma) from TI. Key features include:
- 24‑bit stereo DAC with high dynamic range and low distortion
- Supports sampling rates up to 192 kHz
- Differential current-output with external I/V conversion required
- Digital input formats: I2S, left-justified, right-justified
- Flexible analog/digital power supply options (noise isolation helps PSRR)
- Suitable for consumer/professional audio applications
- Small package with Tape & Reel (IRTER) packaging for automated assembly
Note: Exact electrical specs (SNR, THD, power, voltages) vary by revision; consult the datasheet for precise figures and recommended external components.

Package

PCM1820IRTER uses a 28-pin TSSOP package (Pb-free, Tape-and-Reel variant).

Pinout

Pin count: 28 pins (SSOP-28).
Function: TI PCM1820IRTER is a stereo digital-to-analog converter (24-bit DAC) with a digital input (I2S/PCM-compatible) and differential current output. It requires external I/V conversion and a reconstruction filter (external op-amps). Supports high sample rates (typical for audio DACs).

Manufacturer

- Manufacturer: Texas Instruments (TI) — historically the Burr-Brown analogue division; TI currently owns and markets the PCM1820 series.
- What kind of company: A global semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (ICs) and related electronic components.

Application

Two-channel high-fidelity DAC. Applications include consumer audio gear (CD/DVD/Blu-ray players, DAC modules, audio interfaces), home theater devices (AV receivers, soundbars), headphone amplification, professional audio equipment, embedded systems needing high-quality D/A conversion, and digital media players. Suitable for low distortion and wide dynamic range using standard I2S/PCM interfaces.
