A good PCB layout for the MAX9911EXT+T involves keeping the input and output traces short and separate, using a solid ground plane, and placing the device close to the power source. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The MAX9911EXT+T requires a single 2.7V to 5.5V power supply. It's recommended to power the device with a clean, low-noise power source. The power sequencing requirements are not critical, but it's recommended to power the device after the input signals are stable.
The MAX9911EXT+T can handle input signal amplitudes up to 5.5V peak-to-peak. However, it's recommended to limit the input signal amplitude to 3.5V peak-to-peak to ensure optimal performance and to prevent damage to the device.
To optimize noise rejection and CMRR, it's recommended to use a differential input configuration, keep the input traces short and balanced, and use a common-mode filter capacitor (e.g., 10nF) between the input pins. Additionally, ensure the device is properly grounded and the power supply is clean and stable.
The MAX9911EXT+T is specified to operate over a temperature range of -40°C to +125°C. However, it's recommended to operate the device within a temperature range of -20°C to +85°C for optimal performance and reliability.
