Detailed Description

Linear Technology DC1716A Demonstration Board.

LTC2473: 16-Bit, Delta Sigma ADC with I2C interface

NOTES
  Setup:
   Set the terminal baud rate to 115200 and select the newline terminator. Equipment
   required is a precision voltage source and a precision voltmeter. Additionally,
   an external power supply is required to provide a negative voltage for Amp V-.
   Set it to anywhere from -1V to -5V. Set Amp V+ to Vcc. Ensure the COM and REF-
   pins are connected to ground. The REF+ pin should be connected to +5V.

  How to test Differential Mode:
   The voltage source should be connected with positive and negative leads to paired
   channels. The voltage source negative output must also be connected to the COM
   pin in order to provide a ground-referenced voltage. Ensure voltage is within
   analog input voltage range -0.3V to +2.5V. 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
