WM8786GEDS/V

Overview

The WM8786GEDS/V 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. The device supports sampling frequencies ranging from 8 kHz to 192 kHz. Key electrical specifications include a signal-to-noise ratio (SNR) of 111 dB (A-weighted at 48 kHz) and total harmonic distortion (THD) of -102 dB. It operates with an analogue supply voltage of 4.5 V to 5.5 V and a digital core supply of 2.7 V to 3.6 V. The component is housed in a 20-lead SSOP package.

Feature Summary

• Stereo 24-bit sigma-delta ADC with differential inputs
• Sampling frequency range from 8 kHz to 192 kHz
• Hardware-controlled interface via pin programming
• Supports I2S, Left Justified, Right Justified, and DSP audio formats

Applications

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

Procurement Notes

Verify the specific suffix GEDS/V indicates a lead-free 20-lead SSOP package with Moisture Sensitivity Level 3. Confirm availability status as distribution channels may list this component as discontinued or limited stock. Ensure compatibility with required operating temperatures ranging from -40°C to +85°C before procurement.

Selection Notes

Select the WM8786GEDS/V when differential analog inputs are required for noise reduction in recording applications. Choose this part if hardware control via pins is preferred over digital serial interfaces like I2C. Ensure the system design accommodates separate analogue (AVDD) and digital (DVDD) power supplies within specified voltage ranges.

Part Context

The WM8786 series was originally developed by Wolfson Microelectronics and later integrated into Cirrus Logic's portfolio following acquisition. The GEDS/V suffix denotes the specific tape-and-reel packaging variant with lead-free composition and extended industrial temperature range capabilities compared to standard commercial variants.

Replacement Considerations

Direct replacements within the same family include the WM8786GEDS/RV, which shares identical electrical characteristics but differs only in reel packaging quantity. Other similar stereo ADCs from Cirrus Logic should be evaluated for pin compatibility and interface requirements.
