Linear Technology DC2071A Demonstration Board.
LTC2373: 16/18-bit 1Msps 8 channel SAR ADC LTC2372: 16/18-bit 500ksps 8 channel SAR ADC LTC2374: 16 bit 1.6Msps 8 channel SAR ADC
Max SCK rate is 100MHz.
NOTES
Setup:
Set the terminal baud rate to 115200 and select the newline terminator.
Equipment required is a precision voltage source (null box) and a precision voltmeter (to monitor voltage source).
No external power supply is required.
Ensure JP1 is installed in the default position from the factory.
How to test:
The voltage source should be connected with positive and negative leads to the positive & negative ADC inputs. Ensure the differential voltage is within the
range of -VREF to +VREF. Swapping input voltages results in a reversed polarity reading.
How to calibrate:
Enter menu item number "3 - Calibrate" and follow the prompts.
Calibration is now stored in EEPROM. Upon startup the calibration values will be restored.
USER INPUT DATA FORMAT:
decimal : 1024
