Bias OUT with a pullup resistor to a potential greater than OUT. Bypass OUT to GND with a 0.01µF or larger capacitor. A2 GND Ground B1 OUT Output Voltage. B1 is shorted to A1 internally. B2 GND Ground. B2 is shorted to A2 internally. Detailed DescriptionOutput Voltage Hysteresis The MAX6069 family consists of precision, two- Output voltage hysteresis is the change in the output terminal, shunt bandgap voltage references. On-chip, voltage at TA = +25°C before and after the device is cycled thin-film resistors are laser-trimmed to provide 0.2% output over its entire operating temperature range. Hysteresis is voltage accuracies. Voltages of +1.25V, +2.048V, +2.5V, caused by differential package stress appearing across and +3.0V are available in a space-saving 4-bump WLP. the bandgap core transistors. The temperature hysteresis value is typically less than 200ppm. Applications InformationTurn-On TimeOutput/Load Capacitance The output capacitance and bias current of the MAX6069 Bypass OUT to GND with a 0.01μF or larger capacitor. greatly affect turn-on settling time. In the Typical Operating In applications where the load or the supply can experience Characteristics, turn-on time is shown with a 10nF out- step changes, additional capacitance will reduce the put capacitor and a 1.2μA bias current. Under these amount of overshoot (or undershoot) and assist the conditions, the MAX6069 settles in about 4ms. Settling circuit’s transient response. time linearly decreases in proportion to the circuit’s bias current. www.analog.com Analog Devices │ 6
