ADS7800JU/1K Frequently Asked Questions (FAQs)
Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The analog input traces should be short and direct, and the digital output traces should be routed away from the analog inputs. Additionally, decoupling capacitors should be placed close to the device's power pins.
The POR circuitry ensures that the device is in a known state after power-up. It is recommended to use an external POR circuit or a supervisor IC to ensure a clean power-up sequence. Not using POR can result in unpredictable behavior, incorrect conversions, and potential damage to the device or surrounding circuitry.
The ADS7800JU/1K's accuracy is affected by temperature, with a typical temperature coefficient of ±1 ppm/°C. To compensate for temperature effects, an external temperature sensor can be used to monitor the device's temperature, and the resulting data can be used to correct the conversion results. Alternatively, the device can be calibrated at multiple temperatures to create a lookup table for temperature compensation.
To ensure EMC and EMI compliance, follow proper PCB layout and routing guidelines, use shielding and grounding techniques, and implement filtering and decoupling on the device's power and signal lines. Additionally, consider using a metal shield or enclosure around the device and surrounding circuitry to reduce radiated emissions.
The ADS7800JU/1K is sensitive to high-frequency noise, including clock noise. To minimize clock noise, use a clock signal with a low slew rate, and consider using a clock buffer or isolator to reduce the clock signal's amplitude and frequency. Additionally, use proper PCB layout and routing techniques to keep the clock signal away from the analog inputs and power lines.
