Low Voltage Reference
The ICL8069 is a 1.2V temperature-compensated voltage
reference. It uses the band-gap principle to achieve excel-
lent stability and low noise at reverse currents down to 50
A.
Applications include analog-to-digital converters, digital-to-
analog converters, threshold detectors, and voltage
regulators. Its low power consumption makes it especially
suitable for battery operated equipment.

NOTES:
2. If circuit strays in excess of 200pF are anticipated, a 4.7
F shunt capacitor will ensure stability under all operating conditions.
3. In normal use, the reverse voltage cannot exceed the reference voltage. However when plugging units into a powered-up test fixture, an
instantaneous voltage equal to the compliance of the test circuit will be seen. This should not exceed 20V.
