TC1762
Preliminary
Functional Description
3.14
Fast Analog-to-Digital Converter Unit (FADC)
The on-chip FADC module of the TC1762 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 3-11, 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:
• V_DDMF/V_DDMF:FADC Analog Part Power Supply (3.3 V)
• V_DDAF/V_DDAF:FADC Analog Part Logic Power Supply (1.5 V)
• V_FAREF/V_FAGND:FADC Reference Voltage (3.3 V)/FADC Reference Ground
