LTC2309: 8-Channel, 12-Bit SAR ADC with I2C Interface.
Linear Technology DC1444A Demonstration Board. LTC2301: 1-Channel, 12-Bit ADCs with I2C Compatible Interface
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. No external power supply is required. Ensure all jumpers on the demo board are installed in their default positions from the factory. Refer to Demo Manual DC1337A. How to test Single-Ended mode: Bipolar Mode: The voltage source should be connected to one of the inputs CH0,...CH7. Ensure the input is within its 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 +4.096V. (Swapping input voltages results in a reversed polarity reading.) Unipolar Mode: The voltage source should be connected to one of the inputs CH0,...CH7. Ensure the input is within its 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 +4.096V. How to test Differential Mode: Bipolar Mode: The voltage source should be connected between paired channels. Ensure both inputs are within their specified absolute input voltage range. (It is easiest to tie the voltage source negative terminal to COM or GND.) Ensure the voltage source is set within the range of 0 to +4.096V (differential voltage range). (Swapping input voltages results in a reversed polarity reading.) Unipolar Mode: The voltage source should be connected between paired channels. (It is easiest to tie the voltage source negative terminal to COM or GND.) Ensure both inputs are within their specified absolute input voltage range. (It is easiest to tie the voltage source negative terminal to COM or GND.) Ensure the voltage source is set within the range of 0 to +4.096V (differential voltage range). USER INPUT DATA FORMAT: decimal : 1024 hex : 0x400 octal : 02000 (leading 0 "zero") binary : B10000000000 float : 1024.0
