Description
1-4
1.2.1
12-Bit Analog-to-Digital Converter
The TLC2543 is a 12-bit, switched-capacitor, successive-approximation ADC.
The device has three control inputs, a chip select, an input-output clock, and
a serial data in address input that are interconnected to the microcontroller.
The TLC2543 has an on-chip 14-channel multiplexer that can select any one
of 11 inputs or any one of three internal self-test voltages. At the end of
conversion, the end-of-conversion (EOC) output goes high indicating to the
microcontroller that the conversion is complete.
The microcontroller supplies the serial data address to, and reads the serial
digital data from, the TLC2543 ADC.
1.2.1.1
Outputs
At the ADC REF+ and REF– inputs, jumper provisions are made to connect
the TLC2543 ADC reference voltage to the 5-V power source that produces
ratiometric measurements, or measurements can be made with respect to an
absolute voltage provided by a TL1431 voltage reference device.
1.2.1.2
Inputs
The 11 EVM inputs are configured to provide access to the ADC for the
following types of conversions:
Three dedicated inputs that include:
An optical sensor
A temperature sensor
A variable resistor
Eight additional user-configurable analog inputs:
Three buffered inputs by using the TLC2264 operational amplifiers.
Five inputs are unbuffered and grounded.
Provisions are made for attaching the eight additional signal lines to the user-
supplied interface connector.
1.2.2
Controller
The controller consists of the following:
The TMS370C712 microcontroller and crystal
The TL7705B power supply voltage monitor
The input select switches
