Si3000 VOICEBAND CODEC WITH MICROPHONE/SPEAKER DRIVE
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).
