1 / 17 page 1 Ultra Low Noise, Precision Voltage Reference ISL21090 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 to10Hz noise with an initial voltage accuracy of 0.02% (2.5V option). The ISL21090 offers 1.25V, 2.5V, and 5.0V 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. Applications •High-End Instrumentation • Precision Voltage Sources for Data Acquisition System, Industrial Control, Communication Infrastructure • Process Control and Instrumentations • Active Source for Sensors Features • Reference Output Voltage Option - 1.25V, 2.5V, and 5.0V (Released) - 7.5V (Coming Soon) • Initial Accuracy: - ISL21090-12 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .±0.03% - ISL21090-25 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .±0.02% - ISL21090-50 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .±0.025% • Output Voltage Noise (0.1Hz to 10Hz). . . . . . . . . . . . 1.0µVP-PTyp (1.25V Option) • Supply Current . . . . . . . . . . . . . . . . . . . .750µA (1.25V Option) • Temperature Coefficient . . . . . . . . . . . . . . . . . . 7ppm/°C Max • Output Current Capability . . . . . . . . . . . . . . . . . . . . . . . . 20mA • Line Regulation . . . . . . . . . . . . . . . . . 6ppm/V (1.25V Option) • Load Regulation . . . . . . . . . . . . . . 2.5ppm/mA (1.25V Option) • Operating Temperature Range. . . . . . . . . . .-40°C to +125°C Related Literature See AN1764, “ISL21090XXEV1Z User’s Guide” FIGURE 1.
