Intersil Announces Low Current Consumption for Low-Noise Voltage References
Intersil Corp. introduced the ISL21009 voltage reference. This reference delivers initial accuracy, along with the company claims is the industry's lowest supply current consumption for low-noise references, making it a suitable choice for industrial and medical instrumentation applications where power is a concern. With less than 3ppm/°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."
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.
The ISL21009 is available now in an 8-lead SOIC package and is priced at $4.04 for the 3ppm/°B version, at $3.74 for the 5ppm/°C version, and $2.65 for the 10ppm/°D version. All pricing is in 1,000-unit quantities.
