[sdiy] unconventional uses for parts

[RMC]

I take it that the list is familiar with TRAC?

"TRAC is a radically new concept which provides field programmable analog 
device capability. Based on a structured design approach, the combination of 
silicon device and powerful, PC based software design tools, removes the 
mystique from analog IC design. TRAC is the analog equivalent of the FPGA.

The heart of the concept is a unique and patented configurable analog cell, 
soft programmed to perform different analog functions:
ADDITION
NEGATE
LOG
ANTILOG
AMPLIFY
Features
Fast structured design and simulation
Instant hardware emulation
Low risk migration to analog ASIC
PC based design tools
Analog signal processing and conditioning "

With a 10MHz BW it'll do nicely for audio!
