Linear Technology DC1011A-B Demonstration Board.
LTC2496: 16-Bit 8-/16-Channel Delta Sigma ADC with Easy Drive Input Current Cancellation
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. No external power supply is required. Ensure all jumpers on the demo board are installed in their default positions from the factory. How to test Single-Ended mode: The voltage source should be connected to the ADC such that the negative lead is connected to COM. The positive lead may be connected to any channel input. Ensure voltage is within analog input voltage range -2.5V to +2.5V. 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 -2.5V 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

Display selected differential channels.
Displaying Single-Ended channels is straightforward; not so with differential because the inputs can take either polarity.
