Detailed Description

Linear Technology DC1925A Demonstration Board with SPI interface.

LTC2376-20: 20-Bit, 250Ksps ADC LTC2377-20: 20-Bit, 500Ksps ADC LTC2378-20: 20-Bit, 1Msps ADC Max SCK rate is 100MHz.

NOTES
  Setup:
   Set the terminal baud rate to 115200 and select the newline terminator. Equipment
   required is a voltage source (preferably low-noise) and a precision voltmeter.
   Ensure all jumpers on the demo board are installed in their default positions
   from the factory. Refer to Demo Manual DC1925A.

  How to test:
   The voltage source should be connected between inputs AIN+ and AIN-. Ensure both
   inputs are within their specified absolute input voltage range. (It is easiest
   to tie the voltage source negative terminal to COM.) Ensure the voltage
   source is set within the range of 0V to +5V (differential voltage range).
   (Swapping input voltages results in a reversed polarity reading.)

USER INPUT DATA FORMAT:
 decimal : 1024
 hex     : 0x400
 octal   : 02000  (leading 0 "zero")
 binary  : B10000000000
 float   : 1024.0
