Precision, Low Noise FGA? Voltage References with
Disable
ISL21060
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.
