The PCM1863DBR and PCM1863DBT from Texas Instruments are part of a family of low-power, highly-integrated audio analog-to-digital converters (ADCs) that offer outstanding performance and flexibility for a range of audio applications. These devices utilize advanced delta-sigma modulation techniques to convert analog audio signals into digital data with high precision and dynamic range.

The PCM1863DBR and PCM1863DBT are ideal for use in professional and consumer audio systems, including AV receivers, soundbars, wireless speakers, and smart audio devices. They are particularly well-suited for systems that require high-quality audio capture, such as voice recognition and active noise cancellation.

Key Features:

• Audio Quality: With a 103-dB signal-to-noise ratio (SNR) and -93-dB total harmonic distortion plus noise (THD+N), these ADCs ensure high-fidelity audio capture, preserving the integrity of the original sound.
• Flexible Inputs: Four selectable single-ended or two differential inputs allow for versatile connection configurations to accommodate various audio sources.
• Programmable Gain: Integrated programmable gain amplifiers (PGAs) enable precise adjustment of input signal levels to optimize performance.
• Low Power Consumption: Designed for efficiency, the devices feature low power consumption, making them suitable for battery-powered applications.
• Advanced Features: On-chip features such as an automatic gain control (AGC), digital filtering, and a flexible audio serial interface facilitate integration and simplify system design.

Product Variants:

The PCM1863DBR and PCM1863DBT differ primarily in their packaging options. The PCM1863DBR is available in a 30-pin TSSOP package, while the PCM1863DBT is offered in a 30-pin TSSOP package with a smaller body size. Both variants are engineered to meet the same performance standards and are fully pin-to-pin compatible, allowing for easy interchangeability in design.

Texas Instruments provides comprehensive technical support for the PCM1863DBR and PCM1863DBT, including detailed datasheets, application notes, and design resources to assist developers in integrating these ADCs into their audio solutions.
