Low-Voltage Reference
General Description
The ICL8069 is a 1.2V temperature-compensated volt-
age reference. It uses the bandgap principle to achieve
excellent stability and low noise at reverse currents down
to 50碌A(chǔ). Maxim鈥檚 ICL8069 also features excellent stabili-
ty, freedom from oscillation.
