The recommended power-up sequence is to apply VCC first, followed by VEE, and then the logic inputs. This ensures proper device operation and prevents latch-up.
To ensure the DS1841N+ is in a known state after power-up, assert the RESET pin low for at least 100 ns to initialize the device. This guarantees a known state for the voltage adjust pins.
The maximum capacitance allowed on the VADJ pin is 100 nF. Exceeding this value may affect the device's stability and performance.
While the DS1841N+ can be used to adjust the output voltage, it is not a voltage regulator in the classical sense. It is designed to provide a adjustable voltage reference, not to regulate voltage in the presence of load changes.
The output voltage (VOUT) can be calculated using the formula: VOUT = (R1 / R2) * (VREF - VEE) + VEE, where R1 and R2 are the resistors connected to the VADJ pin, VREF is the internal reference voltage, and VEE is the negative supply voltage.
