Ultra Low Noise, Precision Voltage Reference

ISL21090

Features

The ISL21090 is a ultra low noise, high DC accuracy precision

voltage reference with wide input voltage range. The ISL21090

uses the new Intersil Advanced Bipolar technology to achieve

sub 1.0µV_P-P(1.25V option) 0.1Hz to 10Hz noise with an initial

voltage accuracy of 0.02% (2.5V option).

• Reference output voltage option

- 1.25V, 2.5V, 5.0V and 7.5V

• Initial accuracy:

- ISL21090-12 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .±0.03%

- ISL21090-25 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .±0.02%

- ISL21090-50 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .±0.025%

- ISL21090-75 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .±0.035%

The ISL21090 offers 1.25V, 2.5V, 5.0V and 7.5V output voltage

options with 7ppm/°C temperature coefficient and also

provides excellent line and load regulation. These devices are

offered in an 8 Ld SOIC package.

• Output voltage noise (0.1Hz to 10Hz) . . . . . . . . . . . . 1.0µV_P-Ptyp

(1.25V option)

The ISL21090 is ideal for high-end instrumentation, data

acquisition and processing applications requiring high DC

precision where low noise performance is critical.

• Supply current . . . . . . . . . . . . . . . . . . . . 750µA (1.25V option)

• Temperature coefficient . . . . . . . . . . . . . . . . . . 7ppm/°C max

• Output current capability . . . . . . . . . . . . . . . . . . . . . . . . 20mA

Applications

• High-end instrumentation

• Line regulation . . . . . . . . . . . . . . . . . . .6ppm/V (1.25V option)

• Load regulation . . . . . . . . . . . . . . 2.5ppm/mA (1.25V option)

• Operating temperature range. . . . . . . . . . . .-40°C to +125°C

• Precision voltage sources for data acquisition system,

industrial control, communication infrastructure

• Process control and instrumentations

• Active source for sensors
