Texas Instruments recommends a 4-layer PCB with a dedicated analog ground plane, and to keep the analog and digital signals separate. The analog input traces should be short and shielded, 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 ADS8323Y/250 has a built-in POR circuit that resets the device when the power supply voltage rises above 1.5V. To ensure proper operation, the power supply voltage should be ramped up slowly (less than 10ms) and the digital interface should be held in a reset state until the power supply voltage reaches its nominal value.
The maximum sampling rate of the ADS8323Y/250 is 250kSPS. However, the actual sampling rate may be limited by the device's power consumption, which increases with the sampling rate. At 250kSPS, the device's power consumption is approximately 15mW, and it can be reduced to around 5mW at lower sampling rates.
The ADS8323Y/250 does not require calibration, as it has an internal calibration circuit that corrects for offset and gain errors. However, the device's performance can be optimized by adjusting the internal reference voltage and gain settings through the device's digital interface.
The ADS8323Y/250 is designed to meet the EMC and EMI requirements of various regulatory bodies, including the European Union's EMC Directive and the US Federal Communications Commission (FCC) regulations. To ensure compliance, the device should be used in a system that meets the relevant regulatory requirements, and proper PCB layout, grounding, and shielding techniques should be employed.
