WM8510

Mono CODEC with Speaker Driver

DESCRIPTION

FEATURES

•

Mono Codec:

The WM8510 is a low power, high quality mono codec designed

for Voice over Internet Protocol (VoIP) and Digital Telephones.

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

48kHz

The device integrates support for one pseudo-differential and

one single ended input (Handset Mic and Speaker Mic) and

includes drivers for speakers or headset, and mono line output,

making it ideal for Telephone designs. External component

requirements are reduced as no separate microphone or

earpiece amplifiers are required.

•

DAC SNR 93dB, THD -84dB (‘A’-weighted @ 8 – 48ks/s)

ADC SNR 90dB, THD -80dB (‘A’-weighted @ 8 – 48ks/s)

On-chip Headphone/Speaker Driver with ‘cap-less’ connect

40mW output power into 16Ω / 3.3V SPKVDD

BTL speaker drive 0.8W into 8Ω / 5V SPKVDD

•

Earpiece Line output

Multiple analog inputs, plus analog bypass path (0 or -10dB)

Mic Preamps:

Two Microphone Interfaces

Advanced Sigma Delta Converters are used along with digital

decimation and interpolation filters to give high quality audio at

sample rates from 8 to 48ks/s.

One pseudo-differential input

One single ended input

Programmable preamp gain

Psuedo differential inputs with common mode rejection

Programmable ALC / Noise Gate in ADC path

Additional digital filtering options are available in the ADC path,

to cater for application filtering such as ‘wind noise reduction’,

plus an advanced mixed signal ALC function with noise gate is

provided.

•

Low-noise bias supplied for microphone

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.

Other features

•

Digital Playback Limiter

Programmable ADC High Pass Filter (wind noise reduction)

Programmable ADC Notch Filter

On-chip PLL

The WM8510 operates at supply voltages from 2.5 to 3.6V,

although the digital core can operate at voltages down to 1.62V

to save power. The speaker and mono outputs use a separate

supply of up to 5V which enables increased output power if

required. Different sections of the chip can also be powered

down under software control by way of the selectable two or

three wire control interface.

Low power, low voltage

2.5V to 3.6V (digital core: 1.62V to 3.6V)

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

•

28 pin SSOP package

WM8510 is supplied in a convenient 28-pin SSOP package,

offering high levels of functionality in easy to use package.

APPLICATIONS

•

VoIP Telephones

Digital Telephones

Conference Speaker-phone

Mobile Telephone Hands-free Kits
