PCM1716E/2K

ADCs/DACs - Special Purpose Overview

The PCM1716E/2K is a stereo digital-to-analog converter featuring a 24-bit resolution and support for sampling frequencies up to 96 kHz. It utilizes an enhanced multi-level delta-sigma modulator architecture with an internal 8x oversampling digital filter. The device operates on a single +5V supply, accepting standard, I2S, or left-justified audio data formats via a serial interface. Key performance metrics include a signal-to-noise ratio of 106 dB and a dynamic range of 106 dB at 44.1 kHz. It is housed in a 28-lead SSOP package.

ADCs/DACs - Special Purpose Applications

• CD players
• DVD-Audio systems
• Music instruments

ADCs/DACs - Special Purpose Procurement Notes

Verify the component revision and manufacturing date code against current inventory records. Confirm that the SSOP-28 package dimensions match the target PCB footprint. Ensure that the power supply sequencing avoids latch-up conditions by maintaining a voltage difference of less than 0.1V between analog and digital rails during ramp-up.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high-fidelity audio conversion with a single +5V supply. The PCM1716 supports system clocks of 256fs, 384fs, 512fs, or 768fs. Note that 768fs operation is not supported at a 96kHz sampling rate. The device includes an internal crystal oscillator circuit accessible via XTI and XTO pins.

ADCs/DACs - Special Purpose Part Context

The PCM1716 is part of the Burr-Brown (now Texas Instruments) audio DAC portfolio. It is designed for mid-to-high-grade digital audio applications. The 'E' suffix indicates the SSOP-28 package, and '/2K' denotes the reel packaging quantity of 2000 units.
