Notes

2/ All typical values are measured at +25°C.

3/ Characteristics are guaranteed by design, not production tested.

4/ Accuracy applies over the full operating Power Supply voltage range, Full operating Temperature range, Reference Frequency range,

10% Signal Amplitude variation and 10% Reference Harmonic distortion.

5/ For ESD protection the RDC5028 features limiting resistors in series with diodes. Proper ESD precautions are strongly recommended

to avoid functional damage or performance degradation.

6/ All testing at nominal voltage.

7/ All unused inputs shall be tied to Ground. Bit 1 is always the MSB.

8/ See Application Note 1, page 16 and Table II, page 19 "Using INL Error Correction Factors to Improve Accuracy"

9/ Specification de-rated to reflect Total Dose Rate (1019 condition A) to 1 Mrad(Si) @ 25°C.
