WM8737L

Stereo ADC with Microphone Preamplifier

DESCRIPTION

FEATURES



SNR 97dB (‘A’ weighted @ 3.3V, 48kHz, normal power

mode)

THD –84dB (at –1dB, 3.3V, normal power mode)

Complete Stereo / Mono Microphone Interface

The WM8737L is a low power stereo audio ADC designed

specifically for portable applications such as minidisc and

memory audio / voice recorders.



The device offers three sets of stereo inputs, which can be

configured for line-level signals, for internal or table-top

microphones, or for DC measurement (battery monitor). A

programmable gain amplifier can be used for automatic level

control (ALC) with user programmable hold, attack and

decay times. The device also has a selectable high pass

filter to remove residual DC offsets.

Programmable microphone preamp

Automatic Level Control

Low-noise microphone bias voltage



Configurable Power / Performance

Low Power Mode

8.5mW at AVDD = 1.8V (stereo, mic preamps off)

20mW at AVDD = 3.3V (stereo, mic preamps off)



Low Supply Voltages

If the signal source is mono, the WM8737L can run in mono

mode, saving power. It can also mix two channels to mono,

either in the analogue or the digital domain.

Analogue 1.8V to 3.6V

Digital core: 1.42V to 3.6V

Digital I/O: 1.8V to 3.6V

Master or slave mode clocking schemes are offered. Stereo

24-bit multi-bit sigma-delta ADCs are used with digital audio

output word lengths from 16-32 bits, and sampling rates

from 16kHz to 96kHz supported.



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

Audio sample rates: 16, 22.05, 24, 32, 44.1, 48, 88.2, 96kHz

generated internally from master clock



32-pin QFN package, 5 x 5 x 0.9mm

The device is controlled via a 2 or 3 wire serial interface.

The interface provides access to all features including gain

controls, analogue or digital mono mixing, and power

management facilities. The device is supplied in a leadless

5x5mm QFN package.

APPLICATIONS



Memory Audio / Voice Recorders

Minidisc Recorders

Portable Digital Music Systems
