PCM1865DBT

ADCs/DACs - Special Purpose Overview

The PCM1865DBT is a four-channel audio analog-to-digital converter (ADC) from Texas Instruments, part of the PCM186x series. It features a software-controlled architecture with a TSSOP-30 package. The device supports sampling rates up to 192 kHz and offers a typical signal-to-noise ratio (SNR) of 110 dB. Operating within a temperature range of -40°C to +125°C, it integrates programmable gain amplifiers and digital filters for high-fidelity audio capture.

ADCs/DACs - Special Purpose Feature Summary

• Four-channel independent synchronous audio acquisition
• Software-configurable via I²C/SPI interfaces
• Supports sampling rates from 8 kHz to 192 kHz
• Integrated anti-aliasing and digital filtering

ADCs/DACs - Special Purpose Applications

• Multi-channel professional audio recording systems
• High-end home theater and surround sound receivers
• Smart conference microphone arrays
• Industrial acoustic monitoring equipment

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DBT' against the manufacturer's official datasheet to confirm the exact tape-and-reel quantity and moisture sensitivity level. Ensure the ordering information matches the required packaging format for surface-mount assembly processes.

ADCs/DACs - Special Purpose Selection Notes

Select this component when four synchronized audio channels are required in a compact form factor. The software control capability allows for flexible gain and filter configuration without additional hardware changes, simplifying design iterations for multi-standard audio applications.

ADCs/DACs - Special Purpose Part Context

This model belongs to the PCM186x family of high-performance audio ADCs. It shares the core conversion architecture with variants like the PCM1861 and PCM1864 but distinguishes itself through its specific software-controlled interface and four-channel input configuration optimized for complex audio processing tasks.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible substitutes within the same family include the PCM1861 and PCM1864. Verify that the replacement variant supports the required channel count and control interface (software vs. hardware) before integration.
