The maximum voltage that can be applied to the VIN pin is 6V, as specified in the datasheet. Exceeding this voltage may damage the device.
To ensure accurate voltage monitoring, make sure to use a low-impedance voltage source, keep the input traces short and away from noise sources, and use a bypass capacitor (e.g., 0.1uF) between VIN and GND.
The EN (enable) pin is used to turn the device on or off. Connect EN to VIN to enable the device, or connect EN to GND to shut it down. This pin can be used to reduce power consumption when the device is not in use.
The output voltage of the LTC2900-1 is proportional to the input voltage, with a gain of 1/4. For example, if the input voltage is 5V, the output voltage will be approximately 1.25V.
The recommended operating temperature range for the LTC2900-1 is -40°C to 125°C. Operating the device outside this range may affect its performance and reliability.
