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
