Intersil Delivers the Industry’s Lowest Current Consumption for Low-Noise Voltage References

Intersil’s ISL21009 Combines Output Voltage Noise of 4μVpp (0.1Hz to 10Hz) and Supply Current Consumption of Just 180µA (Max, Over Temperature)

Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today introduced the ISL21009 voltage reference. This reference delivers initial accuracy, along with the industry’s lowest supply current consumption for low-noise references, making it the ideal choice for industrial and medical instrumentation applications where power is a concern.

Intersil’s ISL21009 offers the most power savings of any low-noise voltage reference on the market. With less than 3ppm/degrees C of temperature drift, this device provides very precise performance, allowing for accurate measurements even in noisy environments with great temperature variations.

“This combination of precision and low power consumption provides a new benchmark for precision voltage references,” said Lisa Wong, marketing manager for Intersil’s Precision Analog products group. “The ISL21009 provides new levels of power efficiency for precision instrumentation and data acquisition equipment.”

High Precision, Low Noise and Low Current Consumption
The ISL21009 features very low noise (4μVpp for 0.1Hz to 10Hz), low operating current (180μA, max), and 3ppm/°C of temperature drift. In addition, the ISL21009 family features guaranteed initial accuracy as low as ±0.5mV. This combination of high initial accuracy, low temperature drift, and low output noise performance of the ISL21009 enables versatile high performance control and data acquisition applications with low power consumption.
