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 PGA/compressor interface, high dynamic range analog-to-digital converter, an external DSP/µC handling signal processing, or a low distortion digital-to-analog converter with a balanced H-Bridge speaker driver. It supports a CMOS digital interface 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.

The AIC111 comes in a 32-pin QFN 5×5-mm package. A 32-pad solder ball bumped flip chip die that comes in waffle packs or tape and reel is in preview and will be available 3rd quarter 2003.
