The ISL21090 is an ultra-low noise, high DC accuracy precision voltage reference with a wide input voltage range. The ISL21090 uses Renesas' 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 a 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.
