WM8786GEDS/RV

Overview

The WM8786GEDS/RV is a stereo audio analog-to-digital converter (ADC) from Cirrus Logic, designed for high-performance recordable media applications. It features differential inputs and delivers PCM output data with 24-bit word lengths and sampling rates ranging from 8 kHz to 192 kHz. The device utilizes multi-bit sigma-delta ADCs with digital filters and includes a high-pass filter to remove residual DC offsets. Key electrical specifications include an SNR of 111 dB (A-weighted at 48 kHz) and THD of -102 dB. It operates with analogue supply voltages between 4.5 V and 5.5 V and digital core supplies between 2.7 V and 3.6 V. The component is housed in a 20-lead SSOP package.

Feature Summary

• Stereo 24-bit sigma-delta ADC with differential inputs supporting 8–192 kHz sampling rates
• High signal-to-noise ratio (SNR) of 111 dB A-weighted and total harmonic distortion (THD) of -102 dB
• Hardware-controlled interface allowing master or slave clocking modes and programmable audio formats (I2S, Left/Right Justified, DSP)
• Integrated digital high-pass filter for DC offset removal and linear phase FIR digital filtering

Applications

• Recordable DVD Players
• Personal Video Recorders
• High End Sound Cards
• Studio Audio Processing Equipment

Procurement Notes

Verify the ordering suffix RV indicates tape and reel packaging with a quantity of 2,000 units. Confirm the temperature range is -40°C to +85°C and that the package is lead-free with Moisture Sensitivity Level 3. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when differential analog inputs are required for low-noise audio digitization. Ensure the system design accommodates separate analogue (4.5–5.5 V) and digital (2.7–3.6 V) power supplies. Verify compatibility with the desired audio interface format (I2S, Left/Right Justified, or DSP) via hardware pin configuration.

Part Context

The WM8786GEDS/RV belongs to the WM8786 series of stereo audio ADCs manufactured by Cirrus Logic. It is functionally equivalent to the WM8786GEDS/V, differing primarily in packaging form factor, with the RV variant supplied in tape and reel for automated assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other Cirrus Logic stereo ADCs within the same family for potential functional compatibility if sourcing constraints exist.
