1. Maximum electrical operating range, not valid conversion range.
1. All ACCURACY numbers are based on processor and system being in WAIT state (very little activity and no IO switching)
and that adequate low‐pass filtering is present on analog input pins (filter with 0.01 μF to 0.1 μF capacitor between analog
input and VREFL). Failure to observe these guidelines may result in system or microcontroller noise causing accuracy errors
which will vary based on board layout and the type and magnitude of the activity.
Data transmission and reception during data conversion may cause some degradation of these specifications, depending on
the number and timing of packets. It is advisable to test the ADCs in your installation if best accuracy is required.
2. R
not fully charge the input circuitry of the ATD resulting in accuracy error.
3. Analog input must be between V
4. The resolution is the ideal step size or 1LSB = (V
5. Differential non‐linearity is the difference between the current code width and the ideal code width (1LSB). The current
code width is the difference in the transition voltages to and from the current code.
6. Integral non‐linearity is the difference between the transition voltage to the current code and the adjusted ideal transition
voltage for the current code. The adjusted ideal transition voltage is (Current Code–1/2)*(1/((V
7. Zero‐scale error is the difference between the transition to the first valid code and the ideal transition to that code. The
Ideal transition voltage to a given code is (Code–1/2)*(1/(V
8. Full‐scale error is the difference between the transition to the last valid code and the ideal transition to that code. The ideal
transition voltage to a given code is (Code–1/2)*(1/(V
9. Input leakage error is error due to input leakage across the real portion of the impedance of the network driving the analog
pin. Reducing the impedance of the network reduces this error.
10. Total unadjusted error is the difference between the transition voltage to the current code and the ideal straight‐line trans‐
fer function. This measure of error includes inherent quantization error (1/2LSB) and circuit error (differential, integral, zero‐
scale, and full‐scale) error. The specified value of E
