Precision Bandgap Voltage Reference Provides Exceptional Initial Accuracy at Input Voltages of up to 36V

ISL21090 Delivers Half the Noise at Half the Power of Competing Products

Milpitas, CA, (PresseBox) - The newest precision voltage reference from Intersil Corporation (NASDAQ Global Select: ISIL) features low noise, low temperature drift and meets the low power requirements of high end and portable instrumentation systems.

The ISL21090 is a wide input range, low noise precision bandgap voltage reference that provides half the noise of alternative solution with only half the power consumption. The device features exceptionally high initial, or 'start-up,' accuracy of +/-0.02%. The combination of low current consumption of 930microAmps, typical, and low noise of only 1.9microVpp (0.1Hz to 10Hz), makes the ISL21090 an excellent choice for high-end instrumentation systems up to 24 bits, and for process control, communications and data acquisition systems. It can accept input voltages up to 36V, compared with typical 18V ratings of alternative products.

Features and Specifications

- Wide operating range: 4.7V to 36V input voltage
- 2.5V reference output
- 7ppm/degree C temperature coefficient
- 10mA output current capability
- 18ppm/V line regulation; 17ppm/microAmp load regulation
- 20ppm long-term drift

Pricing and Availability

The ISL21090 is available now in 8-pin SOIC packages, with prices starting at $2.90 each in 1,000-unit quantities. For more information please visit
