The deviation of a code from a straight line which connects the two endpoints of the A/D
Converter transfer function. One endpoint is located 1/2 LSB below the first code transition
and the other endpoint is located 1/2 LSB beyond the code transition to all ones. Units in
percent of full-scale.
The deviation of a code’s width from the ideal width. Units in LSB’s.
The deviation of the last code transition from the ideal (VREF-3/2 LSB’s). Units in LSBs.
The deviation of the first code transition from the ideal (1/2 LSB above AGND) when in
unipolar mode (BP/UP low). Units in LSBs.
The deviation of the mid-scale transition (011...111 to 100...000) from the ideal (1/2 LSB
below AGND) when in bipolar mode (BP/UP high). Units in LSBs.
The deviation of the first code transition from the ideal when in bipolar mode (BP/UP high).
The Ideal is defined as lying on a straight line which passes through the final and mid-scale
code transitions. Units in LSBs.
The absolute maximum positive voltage allowed for either accurate system calibration or
accurate conversions. Units in volts.
The absolute maximum negative voltage allowed for either accurate system calibration or
accurate conversions. Units in volts.
The CS5501/CS5503 calibrate their offset to the voltage applied to the AIN pin when in system
calibration mode. The first code transition defines Unipolar Offset when BP/UP is low and the
mid-scale transition defines Bipolar Offset when BP/UP is high. The Offset Calibration Range
specification indicates the range of voltages applied to AIN that the CS5501 or CS5503 can
accept and still calibrate offset accurately. Units in volts.
The voltages applied to the AIN pin in system-calibration schemes define the CS5501/CS5503
analog input range. The Input Span specification indicates the minimum and maximum input
spans from zero-scale to full-scale in unipolar, or from positive full scale to negative full scale
in bipolar, that the CS5501/CS5503 can accept and still calibrate gain accurately. Units in
volts.
