PCM2704DBR Description

Short technical summary and product information.

The PCM2704DBR from Texas Instruments is a stereo audio digital-to-analog converter (DAC) designed for USB audio applications. It supports full-speed USB 1.1 specifications and operates with a single 12-MHz clock source. This device provides a 16-bit resolution and achieves a typical Signal-to-Noise Ratio (SNR) of 98 dB, with a Total Harmonic Distortion plus Noise (THD+N) as low as 0.006% under specific conditions.

 

The PCM2704DBR integrates a USB interface, eliminating the need for a dedicated device driver. It supports both bus-powered and self-powered operation, with supply voltages ranging from 3V to 3.6V or 5V. The DAC features adaptive isochronous transfer for playback and includes an on-chip clock generator.

 

Key analog performance metrics include a dynamic range of 98 dB. The device incorporates an oversampling digital filter with specified pass-band ripple and stop-band attenuation. It offers multiple functions, including up to eight Human Interface Device (HID) interfaces depending on settings.

 

This component is housed in a 28-SSOP package, suitable for surface mounting. It provides analog outputs and an S/PDIF output with SCMS. The operating temperature range is -25°C to 85°C, making it suitable for various environmental conditions.
