ISL21090开发板套件编程器的评估演示板及套件规格书PDF中文资料

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

voltage accuracy of 0.02 (2.5V option).

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.

The ISL21090 is ideal for high-end instrumentation, data

acquisition and processing applications requiring high DC

precision where low noise performance is critical.
