The recommended layout and placement for the MAX11123ATI+ involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the analog signal sources. Additionally, it's recommended to use a 4-layer PCB with a dedicated analog power plane and a dedicated digital power plane.
To optimize the performance of the MAX11123ATI+ in noisy environments, use a low-pass filter on the analog input, use a shielded cable for the analog input, and keep the device away from high-frequency noise sources. Additionally, consider using a common-mode filter or a differential amplifier to reject common-mode noise.
The maximum sampling rate that can be achieved with the MAX11123ATI+ is 1Msps (1 million samples per second) in the fast mode, and 500ksps (500 thousand samples per second) in the normal mode. However, the actual sampling rate may be limited by the system's clock frequency and the conversion time.
The MAX11123ATI+ does not require calibration. It has an internal calibration circuit that calibrates the device during power-up. However, it's recommended to perform a system-level calibration to ensure optimal performance in the specific application.
The power consumption of the MAX11123ATI+ depends on the operating mode and the clock frequency. In the normal mode, the typical power consumption is 1.2mA at 3.3V supply voltage, and in the shutdown mode, the typical power consumption is 1μA.
