DESCRIPTION  
The AIC111 IC design specification serves to provide  
product development teams with a guideline for how the  
AIC111 IC is specified and programmable options that are  
available. The document outlines a top-level block  
description of the IC along with system specifications and  
functions. Individual block descriptions and target  
specifications are also outlined.

The Texas Instruments AIC111 is a TI µPower DSP  
compatible, or microcontroller compatible audio codec  
product, or analog interface circuit. The AIC111 is part of  
a comprehensive family of DSP/µC based high-  
performance analog interface solutions. The AIC111 is  
targeted primarily at personal medical devices, such as  
hearing instruments, aural preprocessing applications,  
and low-power headset applications. The AIC111 is used  
in any design requiring a programmable time constant

tailored for TI DSPs with the McBSP protocol such as  
TMS320VC54x DSP family and SPI-based controllers  
such as TI MSP430x family of microcontrollers. The  
AIC111 also has an external microphone or sensor supply  
and bias and power supply up low-battery monitor  
indicator.
