TC1163/TC1164
Preliminary
Functional Description
3.15
Fast Analog-to-Digital Converter Unit (FADC)
The on-chip FADC module of the TC1163/TC1164 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 â contains the differential inputs and the programmable amplifier
⢠The A/D Converter â is responsible for the analog-to-digital conversion
⢠The Data Reduction Unit â contains programmable antialiasing and data reduction
filters
⢠The Channel Trigger Control block â determines the trigger and gating conditions
for the two FADC channels
⢠The Channel Timers â 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:
⢠VDDMF/VDDMF:FADC Analog Part Power Supply (3.3 V)
⢠VDDAF/VDDAF:FADC Analog Part Logic Power Supply (1.5 V)
⢠VFAREF/VFAGND:FADC Reference Voltage (3.3 V)/FADC Reference Ground
