概述

Description

PCM4202DBR is Texas Instruments’ 24-bit, stereo analog-to-digital converter (ADC) in a DBR package. It converts differential analog audio inputs to digital PCM data using a delta-sigma architecture, delivering standard digital formats (I2S/left-justified, etc.) to a host processor. Targeted for professional audio front-ends (interfaces, mixers, recorders), it emphasizes low noise and wide dynamic range. The DBR suffix denotes a specific lead-free package variant. For exact specifications—sampling-rate range (up to high‑resolution rates), SNR/THD, input impedance, supply voltages, references, and pinout—see the PCM4202 datasheet and TI packaging documentation.

Features

Here are the typical features of the PCM4202DBR (TI PCM4202 in DBR package):
- Dual-channel 24-bit delta-sigma ADC
- Differential analog inputs with programmable gain per channel
- Wide sample rate range, up to 192 kHz
- On-chip digital decimation/filter with multiple output formats
- Flexible digital interface: I2S, Left-Justified, and other PCM formats; supports 24-bit data
- Master/slave clock operation with external clock input and clock output option
- Low-noise, high-dynamic-range performance for professional audio
- Internal references and bias circuitry available
- Suitable for compact, low-power audio capture applications
Note: exact electrical specs (SNR, THD, input ranges, power, etc.) are in the official datasheet.

Package

The PCM4202DBR comes in a leadless 28‑pin QFN package (5x5 mm).

Pinout

- Pin count: 28 pins (DBR package)
- Function: Two-channel, 24-bit stereo ADC with differential analog inputs; provides serial digital audio output (I2S/Left-Justified) and a serial control interface (SPI-like) for register configuration; separate analog/digital power pins and grounds.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- Company type: A US-based multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits for electronics and electrical devices.

Application

Dual-channel, 24-bit ADC for high‑fidelity audio capture. Applications: professional audio interfaces and digital mixers, recording/post‑production gear, conferencing/telepresence systems, broadcast front‑ends, sound cards/DAW peripherals, and general instrumentation requiring low-noise, high‑dynamic‑range multichannel ADC.
