Design Notes
The 5962-85127023A requires three power supplies: +5V for logic, +12V for analog, and -12V for analog. Use separate analog and digital ground planes to minimize noise. Decouple each supply pin with a 0.1µF ceramic capacitor placed as close to the pin as possible, and add a 10µF tantalum capacitor for bulk decoupling. Ensure the analog supplies are clean and well-regulated, as noise on these rails directly affects conversion accuracy.
For optimal performance, place the ADC close to the analog signal source to minimize trace length and reduce noise pickup. Use a ground plane under the device and route analog and digital signals separately. The 28-LCC package has a large thermal pad; solder it to a copper pour for heat dissipation. Keep digital output traces short and avoid routing them near analog input traces to prevent crosstalk.
A common mistake is driving the analog input beyond the specified range, which can cause incorrect conversions or damage. Ensure the input signal is within 0-10V or 0-20V range as configured. Also, do not leave the 12/8 pin floating; tie it to VLOGIC or DGND to select the desired data format. The STS pin indicates conversion status; poll it or use it as an interrupt to avoid reading data during conversion.
