Low-Voltage Reference
General Description
The ICL8069 is a 1.2V temperature-compensated voltage reference. It uses the bandgap principle to achieve excellent stability and low noise at reverse currents down to 50µA. Maxim's ICL8069 also features excellent stability, freedom from oscillation.
Features
o Temperature Coefficient Guaranteed to 10ppm/°C max o Low Bias Current: 50µA min o Low Dynamic Impedance o Low Reverse Voltage o Low Cost
ICL8069
Applications
Analog-to-Digital Converters Digital-to-Analog Converters Threshold Detectors Voltage Regulators Portable Instruments

Low-Voltage Reference ICL8069
ABSOLUTE MAXIMUM RATINGS
Reverse Voltage .....(Note 1) Forward Current .........10mA Reverse Current .........10mA Power Dissipation.......Limited by Max Forward/Reverse Current Storage Temperature Range .....-65°C to +150°C Operating Temperature Ranges ICL8069C ....0°C to +70°C ICL8069E ..........-40°C to +85°C ICL8069M .......-55°C to +125°C Lead Temperature (soldering, 10sec) .....+300°C
Note 1: 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.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

(Note 2) PARAMETER Output Voltage IR = 500µA ICL8069A Output Voltage Temperature Coefficient IR = 500µA, TA = operating temperature range (Note 3) 50µA IR 5mA IR = 50µA, IR = 500µA IF = 500µA 10Hz f 10kHz, IR = 500µA 0.050 ICL8069B ICL8069C ICL8069D Output Voltage Change Reverse Dynamic Impedance Forward Voltage Drop RMS Noise Voltage Reverse Current Range 15 1 0.6 0.7 5 5 CONDITIONS MIN 1.20 TYP 1.23 MAX 1.25 10 25 ppm/°C 50 100 20 2 2 1 mV V µV mA UNITS V
Note 2: If circuit strays in excess of 200pF are anticipated, a 4.7µF shunt capacitor will ensure stability under all operating conditions. Note 3: For military devices, measurements are made at +25°C, -55°C, and +125°C, while for commercial devices measurements are made at +25°C, 0°C, and +70°C. The units are then classified as a function of the worst-case TC. Sample tested to 0.1% AQL.
