The MAX11122ATI+ requires careful layout and placement to ensure optimal performance. It is recommended to follow the layout guidelines provided in the Maxim Integrated Products application note AN5121, which includes recommendations for PCB layout, component placement, and routing.
To minimize high-frequency noise and EMI, it is recommended to use a multi-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. Additionally, use shielding and filtering components, such as ferrite beads and capacitors, to reduce noise and EMI. It is also recommended to follow the EMI reduction guidelines provided in the Maxim Integrated Products application note AN5121.
The recommended power-up sequence for the MAX11122ATI+ is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD). This ensures that the analog circuitry is powered up before the digital circuitry, which helps to prevent latch-up and ensures proper operation.
The MAX11122ATI+ requires calibration to ensure optimal performance. The calibration process involves adjusting the internal offset and gain of the ADC to match the specific requirements of the application. The calibration process is described in detail in the Maxim Integrated Products application note AN5121.
The maximum sampling rate of the MAX11122ATI+ is 1Msps (million samples per second). However, the actual sampling rate may be limited by the specific application and the performance of the external clock source.
