3.15

Fast Analog-to-Digital Converter Unit (FADC)

The on-chip FADC module of the TC1165/TC1166 basically is a 2-channel A/D converter

with 10-bit resolution that operates by the method of the successive approximation.

As shown in Figure 3-12, the main FADC functional blocks are:

•

The Input Stage — contains the differential inputs and the programmable amplifier

•

The A/D Converter — is responsible for the analog-to-digital conversion

•

The Data Reduction Unit — contains programmable antialiasing and data reduction

filters

•

The Channel Trigger Control block — determines the trigger and gating conditions

for the two FADC channels

•

The Channel Timers — can independently trigger the conversion of each FADC

channel

•

The A/D Control block is responsible for the overall FADC functionality

The FADC module is supplied by the following power supply and reference voltage lines:

•

DDMF/VDDMF:FADC Analog Part Power Supply (3.3 V)

•

DDAF/VDDAF:FADC Analog Part Logic Power Supply (1.5 V)

•

FAREF/VFAGND:FADC Reference Voltage (3.3 V)/FADC Reference Ground
