ISL21090B75中文资料超低噪音、高精度电压基准源数据手册Renesas规格书

描述 Description

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.
