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
μ
Power DSP
compatible, or microcontroller compatible audio codec
product, or analog interface circuit. The AIC111 is part of
a comprehensive family of DSP/
μ
C 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,
analog-to-digital converter, an external DSP/
μ
C
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.
