ISL60007
Precision 1.25V and 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.
