CONFIGURABLE ANALOG FRONT-END
9.1
Overview
The PAC5526 includes a Configurable Analog Front End accessible through 8 analog and I/O
pins. These pins can be configured to form flexible interconnected circuitry made up of 3
differential programmable gain amplifiers, 4 single-ended programmable gain amplifiers, 4
general purpose comparators, 3 phase comparators, 10 protection comparators, and one buffer
output. These pins can also be programmed as analog feed-through pins, or as analog front end
I/O pins that can function as digital inputs or digital open-drain outputs. The PAC proprietary
configurable analog signal matrix (CASM) and configurable digital signal matrix (CDSM) allow
real time asynchronous analog and digital signals to be routed in flexible circuit connections for
different applications. A push button function is provided for optional push button on, hibernate,
and off power management function.
