The recommended PCB layout for the MAX11080GUU+ is to keep the analog and digital grounds separate, use a solid ground plane, and minimize the distance between the device and the analog signal sources. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To optimize the performance of the MAX11080GUU+ in noisy environments, use a low-pass filter on the analog input signals, use a shielded cable for the analog input signals, and consider using a common-mode filter on the analog input signals. Additionally, ensure that the device is properly decoupled and that the power supply is clean and stable.
The maximum sampling rate that can be achieved with the MAX11080GUU+ is 1.5Msps (megasamples per second) in single-channel mode and 750ksps in dual-channel mode.
The MAX11080GUU+ does not require calibration. It has an internal calibration circuit that calibrates the device during power-up. However, if the device is used in an application that requires high accuracy, an external calibration circuit can be used to improve the accuracy of the device.
The power consumption of the MAX11080GUU+ depends on the operating mode and the sampling rate. In single-channel mode, the power consumption is typically around 12mW at 1.5Msps and 6mW at 750ksps. In dual-channel mode, the power consumption is typically around 24mW at 750ksps.
