PCM1863DBT

ADCs/DACs - Special Purpose Overview

The PCM1863DBT is a stereo audio analog-to-digital converter (ADC) from Texas Instruments, housed in a TSSOP-30 package. It features an integrated universal front end with eight differential analog inputs and supports sampling rates up to 192 kHz at 24-bit resolution. The device delivers a typical signal-to-noise ratio of 110 dB and operates on a single 3.3 V supply with a maximum voltage of 3.6 V. Control is managed via an I2C interface, allowing for software-configurable settings.

ADCs/DACs - Special Purpose Feature Summary

• 110 dB SNR with 24-bit resolution
• Universal front end with 8 differential ADC inputs
• I2C control interface for software configuration
• Supports sampling rates up to 192 kHz

ADCs/DACs - Special Purpose Applications

• Automotive infotainment systems
• Home theater receivers
• Professional audio equipment

ADCs/DACs - Special Purpose Part Context

This component belongs to the PCM186x family of audio ADCs, which share a common universal front-end architecture. While variants like the PCM1860 offer hardware-controlled interfaces and lower noise performance (103 dB), the PCM1863 provides higher dynamic range (110 dB) with flexible software control via I2C.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1860QDBTRQ1 is a verified automotive-grade alternative within the same family. It offers 103 dB SNR and uses a hardware-controlled interface instead of I2C. Designers must verify that the control scheme change does not impact system compatibility.
