PARAMETER
PARAMETER
All voltages with respect to ground. Currents entering the IC are specified positive, and currents exiting the IC are negative.
Input resistors (R
Supply current specified with all outputs set to zero current setting. SDA and SCL are connected to V
through R
The output voltage range must be satisfied to ensure the device meets its accuracy and linearity specifications.
Temperature drift excludes drift caused by external resistor.
Differential linearity is defined as the difference between the expected incremental current increase with respect to position
and the actual increase. The expected incremental increase is the full-scale range divided by 127.
Guaranteed by design.
Integral linearity is defined as the difference between the expected value as a function of the setting and the actual value.
The expected value is a straight line between the zero and the full-scale values proportional to the setting.
Timing shown is for fast-mode (400kHz) operation. This device is also backward compatible with I
