PCM4222PFBR

ADCs/DACs - Special Purpose Overview

The PCM4222PFBR is a dual-channel, 24-bit audio analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 216 kHz and features an A-weighted dynamic range of 124 dB. The device operates on a single supply voltage ranging from 3.9 V to 4.2 V and utilizes a serial 3-wire interface for data transmission. Packaged in a 48-pin TQFP (7x7 mm) format, it is designed for high-fidelity audio applications requiring low distortion and high resolution.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 124 dB A-weighted dynamic range
• Dual-channel architecture supporting up to 216 kHz sampling rate
• Serial 3-wire digital audio interface
• Single-supply operation (3.9 V to 4.2 V)

ADCs/DACs - Special Purpose Applications

• High-end audio recording interfaces
• Professional mixing consoles
• Digital audio workstations

ADCs/DACs - Special Purpose Procurement Notes

Verify the package type is 48-TQFP (7x7 mm) and confirm the operating temperature range is -40°C to +85°C. Ensure the supply voltage requirements match the system design, as the device specifies a minimum of 3.9 V and maximum of 4.2 V. Check RoHS compliance status for environmental regulations.

ADCs/DACs - Special Purpose Selection Notes

Select this component when dual-channel, high-resolution audio conversion is required. The 216 kHz max sampling rate suits professional audio standards. Ensure the host processor supports the serial 3-wire interface. Verify that the PCB layout accommodates the 48-TQFP footprint and thermal requirements for the specified operating temperature range.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM4222 series of audio ADCs. It is often evaluated using the PCM4222EVM evaluation module, which includes OPA1632 differential amplifiers for input buffering. The device is distinct from operational amplifiers like the THS4222D, serving specifically as a data converter rather than a signal amplifier.
