ISL21060
Precision Reference with Disable
December 16, 2008
www.DataSheet4U.com
FN6706.3
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 10µVP-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.
