WM8737L  
Stereo ADC with Microphone Preamplifier  
DESCRIPTION  
FEATURES  
•
SNR 95dB (‘A’ weighted @ 3.3V, 48kHz, normal power  
mode)  
THD –90dB (at –0.5dB, 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.

•
Configurable Power / Performance  
Low Power Mode  
-
-
8mW at AVDD = 1.8V (stereo, mic preamps off)  
18.5mW 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 8kHz to 96kHz supported.  
•
•
256fs / 384fs or USB master clock rates: 12MHz, 24MHz  
Audio sample rates: 8, 11.025, 12, 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.
