ISL21009
High Voltage Input Precision, Low Noise
FGA™ Voltage References
The ISL21009 FGA™ voltage references are extrem ely low
power, high precision, and low no ise voltage references
fabricated on Intersil’s proprietary Floating Gate Analog
technology . The ISL21009 features very low noise (4.5µVP-P
for 0.1Hz to 10Hz), low operating current (180µA, Max), and
3ppm/°C of temperature drift. In addition, the ISL 21009
family features guaranteed initial accuracy as low as
±0.5mV.
This combination of high initi al accuracy, low power and low
output noise performance of the ISL21009 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 specificati ons are gua ranteed. Typ values are for information purposes only. Unless otherwise noted, all test s are at
the specified temperature and are pulsed tests, therefore: TJ = TC = TA
NOTE:

NOTES:
4. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in VOUT is divided by the
temperature range; in this case, -40°C to +125°C = +165°C.
5. Thermal Hysteresis is the change of VOUT measured @ T A = +25°C af ter temperature cycling over a specified range, ΔTA. VOUT is read initially
at TA = +25°C for the device under test. The device is temperature cycled and a second VOUT measurement is taken at +25°C. The difference
between the initial VOUT reading and the second VOUT reading is then expressed in ppm. For Δ TA = +165°C, the device under test is cycled
from +25°C to +125°C to -40°C to +25°C.
6. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm/sqrt(1kHrs).
