A good PCB layout for the MAX1290ACEI+T involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the analog signal sources. Additionally, use short traces and avoid crossing digital and analog signals.
The MAX1290ACEI+T requires a single 2.7V to 5.5V power supply. Ensure that the power supply is clean and well-regulated. Power sequencing is not critical, but it's recommended to power up the analog supply (VCC) before the digital supply (VDD).
The MAX1290ACEI+T can achieve a maximum data transfer rate of 100 kbps in SPI mode and 400 kbps in I²C mode.
The internal oscillator calibration is done automatically during power-up. No external calibration is required. However, the oscillator frequency can be trimmed using the OSC_TRIM register to achieve a more accurate clock frequency.
The MAX1290ACEI+T is specified to operate over a temperature range of -40°C to +85°C. However, the device can operate beyond this range, but with reduced performance and accuracy.
