WM8950

ADC with Microphone Input and Programmable Digital Filters

DESCRIPTION

FEATURES

Mono ADC:

The WM8950 is a low power, high quality mono ADC designed

for portable applications such as Digital Still Camera, Digital

Voice Recorder or games console accessories.



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

SNR 94dB, THD -83dB (‘A’-weighted @ 8 – 48ks/s)

Multiple auxiliary analogue inputs

The device integrates support for a differential or single ended

mic. External component requirements are reduced as no

separate microphone amplifiers are required.

Mic Preamps:



Differential or single end Microphone Interface

Programmable preamp gain

Pseudo differential inputs with common mode rejection

Programmable ALC / Noise Gate in ADC path

Advanced Sigma Delta Converters are used along with digital

decimation filters to give high quality audio at sample rates



Low-noise bias supplied for electret microphones

from

8 to 48ks/s. Additional digital filtering options are

available, to cater for application filtering such as wind noise

reduction, noise rejection, plus an advanced mixed signal ALC

function with noise gate is provided.

OTHER FEATURES



5 band EQ

Programmable High-Pass Filter (wind noise reduction)

Fully Programmable IIR Filter (notch filter)

On-chip PLL

An on-chip PLL is provided to generate the required Master

Clock from an external reference clock. The PLL clock can

also be output if required elsewhere in the system.

Low power, low voltage

2.5V to 3.6V (digital: 1.71V to 3.6V)

power consumption 10mA all-on 48ks/s mode

The WM8950 operates at supply voltages from 2.5 to 3.6V,

although the digital supplies can operate at voltages down to

1.71V to save power. Different sections of the chip can also be

powered down under software control by way of the selectable

two or three wire control interface.



4x4x0.9mm 24 lead QFN package

APPLICATIONS



Digital Still Camera

General Purpose low power audio ADC

Games console accessories

Voice recorders

WM8950 is supplied in a very small 4x4mm QFN package,

offering high levels of functionality in minimum board area, with

high thermal performance.
