概要

Description

PCM4222PFBR is a Texas Instruments PCM4222 stereo digital-to-analog converter (DAC) in the PFBR package. It provides 2-channel, 24-bit audio with support up to 192 kHz sampling rate. The DAC uses a sigma-delta architecture with differential current outputs, so it requires external I/V conversion and a subsequent analog output stage (line or headphone amp).
Key points:
- Digital input: supports I2S and other common formats (master/slave modes available)
- Outputs: differential current outputs for each channel (needs external I/V and output buffering)
- Packaging: PFBR denotes the specific TI package variant and leads for surface-mount
Typical use:
- High-fidelity audio gear, sound cards, audio interfaces, DAC modules, consumer and professional audio equipment
For exact electrical specs (SNR, THD, recommended operating conditions, pinout), consult the PCM4222 data sheet and the PFBR package details.

Features

Key features of PCM4222PFBR (TI stereo ADC, PFBR package):
- 24-bit, stereo analog-to-digital converter
- Up to 192 kHz sampling rate
- Differential front-end with programmable gain per channel
- On-chip sigma-delta modulators with digital decimation
- Flexible digital output formats: I2S, left-justified, right-justified (16–24-bit word lengths)
- Clocking: master or slave operation; MCLK input; BCLK/LRCLK support
- Low-noise, high dynamic range and linearity for high‑fidelity capture
- Low power consumption suitable for portable/embedded apps
- 28‑pin PFBR package (QFN) with exposed pad; RoHS-compliant
- Wide operating temperature range (typical industrial temp range)
Note: Exact performance figures (SNR, THD+N, etc.) vary with input conditions and layout—consult the datasheet for precise specs.

Package

The PCM4222PFBR is in a Pb-free 28-pin VQFN package (VQFN-28).

Pinout

- Pin count: 28 pins (PCM4222PFBR in a 28‑pin QFN package).
- Function: Quad (4) differential‑input 24‑bit ADC with digital audio interface. Analog inputs: four differential pairs (AINxP/AINxN). Digital side provides a serial audio output (I2S/PCM/Left‑Justified formats) with clocking (BCLK/LRCLK and optional MCLK). Includes power rails (AVDD, DVDD), grounds, and control pins (RESETN, PDWN, etc.).

Manufacturer

Manufacturer: Texas Instruments (TI). TI is an American multinational semiconductor company, formed from the acquisition of Burr-Brown. It designs and manufactures analog, mixed-signal, and embedded processing integrated circuits used in a wide range of electronics.

Application

- Professional and consumer audio interfaces (sound cards)
- Studio recorders and microphone preamp front-ends
- Conferencing and telepresence systems
- AV devices (soundbars, DAC front-ends, receivers)
- Instrumentation and acoustic sensing requiring high dynamic range
(PCM4222PFBR is a dual-channel 24‑bit, high‑performance ADC suitable for high-fidelity stereo audio capture.)
