Precision Low Power FGA? Voltage References

ISL60002

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 350nA operating current.

Features

? Reference voltages . . . . . 1.024V, 1.2V, 1.25V, 1.8V, 2.048V,

2.5V, 2.6V, 3.0V and 3.3V

? Absolute initial accuracy options . . . . . . . . . ±1.0mV, ±2.5mV

and ±5.0mV

Additionally, the ISL60002 family features guaranteed initial

accuracy as low as ±1.0mV and 20ppm/°C temperature

coefficient. The initial accuracy and temperature stability

performance of the ISL60002 family, plus the low supply

voltage and 350nA power consumption, eliminates the need

? Supply voltage range

- ISL60002-10, -11, -12, -18, -20, -25 . . . . . . . .

- ISL60002-26 . . . . . . . . . . . . . . . . . . . . . . . . . . .

- ISL60002-30 . . . . . . . . . . . . . . . . . . . . . . . . . . .

2.7V to 5.5V

2.8V to 5.5V

3.2V to 5.5V

to compromise thermal stability for reduced power

consumption making it an ideal companion to high resolution,

low power data conversion systems.

Special Note: Post-assembly x-ray inspection may lead to

permanent changes in device output voltage and should be

minimized or avoided. For further information, please see

“Applications Information” on page 34 and AN1533 , “X-Ray

Effects on Intersil FGA References”.
