The PCM2706CPJTR belongs to TI's PCM270xC family of USB audio DACs and is built to deliver an easy, reliable USB-to-audio solution for consumer and embedded products. With an on-chip USB full-speed controller, it supports common USB audio playback scenarios without demanding complex external audio processing hardware.
On the audio side, PCM2706C supports standard sampling rates of 32 kHz, 44.1 kHz, and 48 kHz and integrates a 16-bit delta-sigma stereo DAC with oversampling digital filtering. Designers can choose between analog single-ended output for direct connection to an amplifier stage and S/PDIF output for feeding an external DAC, receiver, or digital audio chain.
The PJTR orderable option indicates a TQFP-32 package supplied in tape-and-reel, making it suitable for volume manufacturing and automated assembly. It is commonly used in USB speakers, USB headphones, USB audio interface boxes, and multimedia accessories that require compact design and dependable USB compatibility.
Combines USB interface, clock recovery, and DAC conversion in a single device, reducing component count and shortening design cycles for USB audio products.
Provides a convenient S/PDIF output path for connection to external DACs, AV receivers, or digital amplifier stages, improving system flexibility.
Single-ended analog output supports straightforward integration into USB headphones and USB speakers, enabling simple analog audio routing and amplification.
Supports 32 kHz, 44.1 kHz, and 48 kHz sampling rates to cover the majority of consumer playback and multimedia audio requirements.
Integrated USB full-speed transceivers and controller designed for USB audio playback implementations in mainstream systems.
Delta-sigma conversion with oversampling digital filtering helps achieve stable audio performance suitable for consumer audio devices.
Offers both analog output and S/PDIF digital output, allowing designers to choose the most appropriate output interface for their audio architecture.
