Description

WM8974CGEFL/V is a Wolfson/Cirrus Logic stereo audio CODEC in a compact package. It combines a stereo DAC and ADC, a built‑in headphone driver, mic bias, and line inputs/outputs in one device, plus a flexible digital audio interface (I2S/PCM/left-justified) and programmable gain/volume controls, mute, and power‑management features. It supports 16–24‑bit data paths with common mobile sampling rates (e.g., 44.1/48 kHz and related rates) and provides separate analog supplies (AVDD) and digital supplies (DVDD) for improved noise performance. The CGEFL/V suffix denotes the exact package/pinout and RoHS lead-free variant. Typical use: feed analog signals to the ADC, route DAC to headphone/line out, and connect the host processor over the digital audio interface; configure routing, gains, and power states via the serial control registers. Applications include mobile devices, portable audio players, voice recorders, and other compact audio I/O designs requiring integrated analog/digital conversion and headphone amplification.

Features

Here are the key features of WM8974CGEFL/V:
- 24-bit stereo ADC and DAC with high dynamic range
- Supports up to high-quality sampling rates (typical up to 96 kHz)
- Digital interface: I2S, left-justified, and right-justified PCM formats
- Built-in headphone driver and stereo line-out
- Analog inputs: mic input with bias and programmable gain; stereo line-in
- Analog outputs: line-out and independent headphone output
- Programmable digital volume control, mute, de-emphasis, and de-pop
- Flexible clocking: internal PLL, master/slave modes, clock in/out
- Low-power operation with multiple power-down modes
- Digital processing options and simple control signals for integration
- RoHS-compliant packaging options (CGEFL/V) suitable for compact/mobile devices
Ideal applications: portable audio devices, MP3 players, set-top boxes, multimedia devices, and other consumer electronics requiring a 24-bit stereo CODEC.

Package

It uses a 28-pin RoHS lead-free QFN package.

Pinout

- Pin count: 28 pins (package variant CGEFL/V).
- Function: WM8974CGEFL/V is a low‑power stereo audio CODEC with ADC and DAC, including a headphone/line output driver, microphone bias/mic input, line input, and a digital audio interface (I2S/PCM) with clocking options.

Manufacturer

WM8974CGEFL/V is manufactured by Wolfson Microelectronics. Wolfson was a British fabless semiconductor company that designs analog/mixed-signal ICs for audio; it was acquired by Cirrus Logic in 2014 and is now part of Cirrus Logic.

Application

WM8974CGEFL/V is a stereo audio CODEC with ADC/DAC and headphone driver. Suitable application areas include:
- Mobile/portable devices: smartphones, tablets, portable media players
- USB audio interfaces and Bluetooth audio adapters
- Voice/communications: VoIP phones, conference systems, handheld recorders
- Headsets/headphones with built‑in mic
- Embedded multimedia: mini hi‑fi, home speakers, IoT audio devices
