The MAX704CSA+ is a sensitive device and requires careful layout and placement to ensure proper operation. It is recommended to follow the layout guidelines provided in the datasheet, including keeping the device away from noise sources, using a solid ground plane, and minimizing lead lengths.
The WDT should be disabled during power-up and power-down to prevent unwanted resets. This can be done by pulling the WDT input low during these periods. Additionally, the WDT should be re-enabled after power-up is complete and the system is stable.
A simple RC circuit can be used to generate a reset signal for the MAX704CSA+. The recommended values are R = 1kΩ and C = 0.1μF. This circuit provides a reset pulse of approximately 100ms, which is sufficient for most applications.
The MAX704CSA+ requires a clean and stable power supply to operate correctly. It is recommended to use a voltage regulator with a low dropout voltage and a high power supply rejection ratio (PSRR) to ensure that the device is properly powered up and down.
The maximum allowed voltage on the input pins of the MAX704CSA+ is VCC + 0.3V. Exceeding this voltage can cause damage to the device. It is recommended to use voltage limiting resistors or clamping diodes to prevent overvoltage conditions.
