Description
The Si3000 is a complete voice band audio codec solution that offers high
integration by incorporating programmable input and output gain/
attenuation, a microphone bias circuit, handset hybrid circuit, and an
output drive for 32
to the Si3034, Si3035, and Si3044 ISOcap North American and
international DAA chipsets through its daisy-chaining serial interface. The
device operates from a single 3.3 to 5 V power supply and is available in
a 16-pin small outline package (SOIC).
