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--(Marketwire - Sep 28, 2011) - The newest precision voltage reference from Intersil Corporation (NASDAQ: 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%. With a low current consumption of 930microAmp, typical, and low noise measuring only 1.9microVpp (0.1Hz to 10Hz), this new voltage reference is an excellent choice for high-end instrumentation systems up to 24 bits, and for process control, communications and data acquisition systems. The ISL21090 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
  • +/-0.02% initial accuracy
  • 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
