Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The analog signals should be routed close to the AGND pin, and the digital signals should be routed close to the DGND pin. Additionally, the input signals should be routed away from the clock and digital signals to minimize noise coupling.
The ADS1601IPFBR requires a clock signal with a frequency between 10 MHz to 50 MHz. A crystal oscillator or a clock generator can be used as the clock source. The clock signal should be connected to the CLK pin, and the clock frequency should be chosen based on the desired sampling rate and system requirements.
The recommended power-up sequence is to apply the analog power supply (AVDD) first, followed by the digital power supply (DVDD). The power-down mode can be entered by pulling the PDWN pin low. When in power-down mode, the device consumes minimal power, and the analog and digital circuits are shut down.
The ADS1601IPFBR has an internal calibration circuit that can be used to calibrate the device. The calibration procedure involves applying a known input voltage to the device and then reading the output code. The gain and offset errors can be calculated and corrected using the calibration data. Texas Instruments provides a calibration procedure in the device datasheet and application notes.
The ADS1601IPFBR has a maximum junction temperature of 150°C. Thermal issues can be handled by providing adequate heat sinking, using a thermal pad or heat sink, and ensuring good airflow around the device. The device should be operated within the recommended temperature range to ensure optimal performance and reliability.
