PCM1716EG4

ADCs/DACs - Special Purpose Overview

The PCM1716EG4 is a stereo digital-to-analog converter featuring a 24-bit resolution and support for sampling frequencies up to 96kHz. 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, delivering a dynamic range of 106dB and THD+N of –96dB at 44.1kHz. It accepts 16-, 20-, or 24-bit audio data via standard, I2S, or left-justified formats. Key features include L/R independent digital attenuation, soft mute, de-emphasis control, and selectable sharp or slow roll-off filters.

ADCs/DACs - Special Purpose Procurement Notes

Verify the component is the Texas Instruments PCM1716EG4 variant. Confirm the package type matches the 28-lead SSOP specification found in official documentation. Ensure compliance with RoHS standards as indicated by the 'G4' suffix. Cross-reference pin assignments and electrical specifications against the manufacturer datasheet before integration.

ADCs/DACs - Special Purpose Selection Notes

Select this component for mid-to-high grade digital audio applications requiring 96kHz sampling rates. It supports system clocks of 256fs, 384fs, 512fs, or 768fs. The device requires separate analog and digital power supplies (+5V) with distinct ground planes to prevent latch-up. Consider the 680µs delay time for professional broadcast applications where latency is critical.

ADCs/DACs - Special Purpose Part Context

The PCM1716EG4 belongs to the PCM1716 family of stereo audio DACs manufactured by Texas Instruments (formerly Burr-Brown). The 'EG4' designation typically indicates a lead-free, RoHS-compliant version of the PCM1716E packaged in a 28-pin SSOP. This part is designed for high-performance audio signal conversion using CMOS technology.

ADCs/DACs - Special Purpose FAQ

What is the maximum sampling frequency supported by the PCM1716?

The PCM1716 supports sampling frequencies ranging from 16kHz to 96kHz.

How is the input data format selected?

Input data format can be selected via software mode using the ML, MC, and MD pins, or in hardware mode using static signals on the I2S and IWO pins. Supported formats include Standard, I2S, and Left Justified.

What is the function of the ZERO pin?

The ZERO pin acts as a zero data flag. If input data is continuously zero for 65,536 BCK cycles, an internal FET switches ON, enabling wired-OR connection with external circuits for zero detect mute functionality.
