The MAX708CUA 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 trace lengths and widths.
The RST pin should be tied to a pull-up resistor and a capacitor to ensure a clean reset signal during power-up and power-down. The recommended values are a 1kΩ pull-up resistor and a 10nF capacitor.
The MAX708CUA can handle clock frequencies up to 125kHz. However, it is recommended to operate the device at a clock frequency of 100kHz or lower to ensure reliable operation and minimize power consumption.
The MAX708CUA requires a stable power supply voltage between 2.7V and 5.5V. It is recommended to use a low-dropout regulator (LDO) to ensure a clean and stable power supply. Additionally, the device requires a bias voltage (VBIAS) between 2.7V and 5.5V, which can be generated using a voltage divider or a dedicated bias voltage generator.
The typical current consumption of the MAX708CUA is around 1.5mA, but it can vary depending on the operating frequency, voltage, and other factors. It is recommended to consult the datasheet for more detailed information on power consumption.
