Applications
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 headphones. The Si3000 can be connected directly
to the Si3034, Si3035, Si3044 and Si3056 North American and
international DAA chipsets through their daisy-chaining serial interface. It
also serves as a companion chip to a FAT ISOmodem chipset with voice
features, providing hardware support for a handset and speaker phone.
The device operates from a single 3.3 to 5 V power supply and is
available in a 16-pin small outline package (SOIC).
