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.
