PCM2707CPJT

ADCs/DACs - Special Purpose Overview

The PCM2707CPJT is a stereo audio digital-to-analog converter (DAC) from Texas Instruments, featuring an integrated USB 2.0 full-speed protocol controller and SpAct clock recovery technology. It operates on a single power supply of 3.3 V or 5 V, supporting bus-powered and self-powered configurations. The device provides 16-bit resolution with sampling rates up to 48 kHz. Key outputs include single-ended headphone drivers and S/PDIF digital output. It utilizes a 32-pin TQFP package and supports I2S interface selection via the FSEL pin.

ADCs/DACs - Special Purpose Feature Summary

• Integrated USB 2.0 full-speed transceiver and HID controls without dedicated device driver software
• SpAct architecture for adaptive isochronous transfer and low clock jitter
• Selectable S/PDIF or I2S digital output via FSEL pin configuration
• On-chip analog phase-locked loops and delta-sigma DAC with 98 dB dynamic range

ADCs/DACs - Special Purpose Applications

• USB headphones
• USB audio speakers
• USB CRT/LCD monitors with audio capabilities
• USB audio interface boxes

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity for the 32-pin TQFP form factor. Check manufacturing date codes against current inventory requirements. Ensure compliance with RoHS directives as specified in the datasheet. Validate that the specific suffix corresponds to the TQFP package variant.

ADCs/DACs - Special Purpose Selection Notes

Select this model when USB connectivity and S/PDIF output are required simultaneously. The PCM2707C differs from the PCM2706C by lacking external ROM interface support but offering I2S capability. Ensure the design accommodates the 32-pin TQFP thermal characteristics. Verify power supply constraints match the 3.3 V or 5 V operating ranges defined in the electrical specifications.

ADCs/DACs - Special Purpose Part Context

This component belongs to the PCM270xC family, which includes PCM2704C, PCM2705C, and PCM2706C. The PCM2707C is distinguished by its TQFP package and SPI/I2S programming interface, contrasting with the SSOP packages of the PCM2704/5C series. It shares core audio performance metrics with the family while offering specific interface flexibility.

ADCs/DACs - Special Purpose Replacement Considerations

PCM2706CPJT serves as a functional alternative if external ROM configuration is needed instead of I2S. PCM2704C or PCM2705C variants require PCB redesign due to different SSOP packaging and pinouts. Direct pin-to-pin replacement is not possible across package types.
