The recommended layout and placement for the MAX11125ATI+ 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 MAX11125ATI+ 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 sources. Additionally, use a common-mode filter on the analog input and use a ferrite bead on the power supply line.
The maximum sampling rate that can be achieved with the MAX11125ATI+ is 1.5Msps (megasamples per second) in the high-speed mode, and 500ksps (kilosamples per second) in the low-power mode.
The MAX11125ATI+ has an internal calibration circuit that can be used to calibrate the device. The calibration process involves writing a specific code to the device's registers to initiate the calibration sequence. The device then adjusts its internal offset and gain to achieve optimal performance.
The power consumption of the MAX11125ATI+ depends on the operating mode. In the high-speed mode, the power consumption is typically around 35mW, while in the low-power mode, the power consumption is typically around 10mW.
