High Precision FGA Voltage References
Manufacturer
Intersil Corporation
Datasheet
Precision 2.50V, 1.08µ-Watt, High
Precision FGA™ Voltage References
The ISL60007 FGA™ voltage references are extremely low
power, very high precision analog voltage references
fabricated in Intersil's proprietary Floating Gate Analog
technology. The ISL60007 features low supply voltage
operation at ultra-low 400nA operating current resulting in
typical 1.08µW power consumption.
In addition, the ISL60007 family features guaranteed initial
accuracy as low as ±0.5mV, temperature coefficients as tight
as 3ppm/°C and long-term stability of 10ppm/√1kHrs.
The initial accuracy and thermal stability performance of the
ISL60007 family plus the low power consumption eliminates
the need to compromise accuracy and thermal stability for
reduced power consumption making it an ideal high
resolution, low power data conversion system.

Ordering Information
*Add "-TK" suffix for tape and reel.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

... IN 0.1µF Turn-On Time The ISL60007 devices operate with ultra-low supply current and thus the time to bias up internal circuitry to final values will be longer than with references that require higher current. Normal turn-on time is typically 4ms. This is shown in Figure 18. Since devices can vary in supply current down to 250nA, turn-on time can last up to about 6ms ...
