Overview

Description

The WM8994ECS/R is Cirrus Logic Wolfson’s WM8994 stereo CODEC in a specific ECS/R package. It integrates two 24-bit ADCs and DACs, a built-in headphone amplifier, microphone bias, and line-in/line-out paths. It provides a flexible digital audio interface (I2S, left-justified, right-justified) and is controllable over I2C. It supports up to 192 kHz sample rates with programmable gain, mute/soft-mute, and digital volume control, making it suitable for portable/embedded audio devices. The ECS/R suffix denotes a package variant; refer to the datasheet for exact electrical specs, pinout, and operating conditions.

Features

Here are the core features of WM8994ECS/R (Wolfson):
- 24-bit stereo ADC and DAC
- Integrated headphone driver
- Analog inputs: microphone bias and line-in; outputs: line-out and headphone
- Flexible digital audio interface: supports I2S (and common PCM formats), left-justified/right-justified
- Digital processing features: programmable digital volume control, mute, and de-pop
- On-chip clocking: supports external master clock with PLL for clock generation
- Low-power operation with various power-down/standby modes
- Compact ECS/R packaging variant suitable for portable applications
Note: For exact electrical specs (voltage ranges, max clock speeds, SNR/DNR, noise performance, and timing), please consult the WM8994ECS/R datasheet.

Package

The WM8994ECS/R comes in a 28-pin QFN package (4×4 mm) with an exposed pad; “R” indicates reel (tape-and-reel) packaging.

Pinout

- Pin count: 28 pins
- Function: WM8994ECS/R is a stereo audio CODEC with integrated ADC/DAC and headphone driver, including mic/line inputs and line outputs, plus a digital audio interface (I2S/PCM) to connect to a host controller.
