Data Sheet January 5, 2006

Precision Low Power FGA™ Voltage References

The ISL60002 FGA™ voltage references are very high precision analog voltage references fabricated in Intersil's proprietary Floating Gate Analog technology and feature low supply voltage operation at ultra-low 400nA operating current.

Additional features include guaranteed initial accuracy as low as ±1.0mV, @ 20ppm/°C temperature coefficient and long-term stability of <<10ppm/√1kHrs and thermal stability performance of the ISL60002 family plus the low supply voltage and 400nA power consumption eliminates the need to compromise thermal stability for reduced power consumption making it an ideal companion to high resolution, low power data conversion systems.

NOTES:

1. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in V (-40°C to +85°C = 125°C, or -40°C to +105°C = 145°C for the ISL60002-33).

2. Thermal Hysteresis is the change in V device under test. The device is temperature cycled and a second V second V device under is cycled from +25°C to +105°C to -40°C to +25°C

3. Guaranteed by device characterization and/or correlation to other device tests.

4. FGA™ voltage reference long term drift is a logarithmic characteristic. Changes that occur after the first few hundred hours of operation are significantly smaller with
