WM8987L

Stereo CODEC for Portable Audio Applications

DESCRIPTION

FEATURES

•

DAC SNR 98dB, ADC 90dB (‘A’ weighted) at 48kHz, 3.3V

On-chip Headphone Driver

The WM8987L is a low power, high quality stereo CODEC

designed for portable digital audio applications.

Single-ended or BTL (differential) drive

>40mW output power on 16Ω / 3.3V

DAC to 32Ω BTL headphone: SNR 86dB, THD -66dB

The device integrates complete interfaces to stereo or mono

microphones and a stereo BTL (differential) or single-ended

headset. External component requirements are reduced as

no separate microphone or headphone amplifiers are

required. Advanced on-chip digital signal processing

performs equalisation, 3-D sound enhancement and

automatic level control for the microphone or line input.

•

Complete Stereo / Mono Microphone Interface

Differential or single-ended mic connection

Programmable ALC / Noise Gate

•

Digital Equaliser

Low Power

Stereo playback 8 mW (1.8V / 1.5V supplies)

Record and playback 13 mW (1.8V / 1.5V supplies)

The WM8987L can operate as a master or a slave, with

various master clock frequencies including 12 or 24MHz for

USB devices, or standard 256f_srates like 12.288MHz and

24.576MHz. Different audio sample rates such as 96kHz,

48kHz, 44.1kHz are generated directly from the master

clock without the need for an external PLL.

•

Low Supply Voltages

Analogue 1.8V to 3.6V

Digital core: 1.42V to 3.6V

Digital I/O: 1.8V to 3.6V

•

256fs / 384fs or USB master clock rates: 12MHz, 24MHz

Audio sample rates: 8, 11.025, 16, 22.05, 24, 32, 44.1, 48,

88.2, 96kHz generated internally from master clock

4x4mm COL package

The WM8987L operates at supply voltages down to 1.8V,

although the digital core can operate at voltages down to

1.42V to save power, and the maximum for all supplies is

3.6 Volts. Different sections of the chip can also be powered

down under software control.

•

APPLICATIONS

The WM8987L is supplied in a very small and thin 4x4mm

COL package, ideal for use in ultra-portable and wearable

systems.

Wireless Headsets

Portable Music Player / Recorders
