The recommended layout and placement for the MAX5481EUD+ involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the power supply. Additionally, it's recommended to use a 4-layer PCB with a dedicated analog layer and a dedicated power layer.
To ensure the MAX5481EUD+ is properly powered, use a high-quality, low-noise power supply with a voltage range of 2.7V to 5.5V. Decouple the power supply with a 1μF ceramic capacitor and a 10μF electrolytic capacitor in parallel, placed as close to the device as possible.
The MAX5481EUD+ can sink or source up to 10mA of current per output. However, it's recommended to limit the current to 5mA per output to ensure reliable operation and to prevent overheating.
To program the MAX5481EUD+ using the I2C interface, use a microcontroller or a dedicated I2C master device to send commands and data to the device. The I2C interface operates at a clock frequency of up to 400kHz, and the device address can be set using the A0, A1, and A2 pins.
The MAX5481EUD+ DAC has a relative accuracy of ±1 LSB (least significant bit) and a differential nonlinearity of ±0.5 LSB. The device also has a monotonicity guarantee, ensuring that the output voltage increases monotonically with the input code.
