Precision Reference with Disable
Data Sheet
September 30, 2009
FN6706.4
Precision, Low Noise FGA™ Voltage
References
The ISL21060 FGA™ voltage references are low power,
high precision voltage references fabricated on Intersil’s
proprietary Floating Gate Analog technology. A new disable
feature allows the device to shut down the output and reduce
supply current drain from 15µA operating to <500nA.
The ISL21060 family features guaranteed initial accuracy as
low as ±1.0mV with drift down to 10ppm/°C. Noise is typically
10µV
P-P
(10Hz BW). This combination of high initial accuracy,
low power and low output noise performance of the ISL21060
enables versatile high performance control and data
acquisition applications with low power consumption.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are at
the specified temperature and are pulsed tests, therefore: T

is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2. Post-reflow drift for the ISL21060 devices will range from 100µV to 1.0mV based on experimental results with devices tested in sockets and also
on FR4 multi-layer PC boards. The design engineer must take this into account when considering the reference voltage after assembly.
