Data Sheet

FN8087.3
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.

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.

NOTES:
1. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in V
OUT
is divided by the
temperature range; in this case, -40°C to +85°C = 125°C.
2. Thermal Hysteresis is the change in V
OUT
measured @ T
A
= 25°C after temperature cycling over a specified range,
Δ
T
A
. V
OUT
is read initially
at T
A
= 25°C for the device under test. The device is temperature cycled and a second V
OUT
measurement is taken at 25°C. The difference
between the initial V
OUT
reading and the second V
OUT
reading is then expressed in ppm. For
Δ
T
A
= 125°C, the device under test is cycled
from +25°C to +85°C to -40°C to +25°C.
3. Guaranteed by device characterization and/or correlation to other device tests.
4. FGA voltage reference long term drift is a logarithmic characteristic. Changes that occur after the first few hundred hours of operation are
significantly smaller with time, asymptotically approaching zero beyond 1000 hours. Because of this decreasing characteristic, long term drift is
specified in ppm/√1kHrs.
