WM8782ASEDS/RV

ADCs/DACs - Special Purpose Overview

The WM8782ASEDS/RV is a stereo audio analog-to-digital converter (ADC) manufactured by Cirrus Logic. It features a 24-bit resolution and supports sampling frequencies from 8 kHz to 192 kHz using multi-bit sigma-delta modulation with oversampling rates of 32x, 64x, or 128x. The device operates in slave mode only, utilizing hardware-controlled interface modes including I2S, Left Justified, and Right Justified formats. It accepts stereo line-level inputs up to 1 Vrms and includes an internal operational amplifier for signals exceeding this level. Power supplies are separated, with the analog section requiring 2.7 V to 5.5 V and the digital core requiring 2.7 V to 3.6 V.

ADCs/DACs - Special Purpose Procurement Notes

Verify that the specific ordering suffix corresponds to the required packaging format. The 'RV' suffix indicates the component is supplied in tape and reel packaging with a standard quantity of 2,000 units per reel. Confirm the temperature range requirement matches the -40°C to +85°C specification provided for this variant.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a dedicated stereo ADC with high dynamic range is required for digital audio recording applications. Ensure the host system provides a master clock signal compatible with the supported multiples (128fs to 768fs). Verify that the available supply voltages align with the separate analog (up to 5.5 V) and digital (up to 3.6 V) requirements.

ADCs/DACs - Special Purpose Part Context
