The ISL21090xxEV1Z evaluation board is designed to measure the performance of the high precision ISL21090 voltage references. The reference has a wide input voltage range from 3.7V to 36V and an initial accuracy of 0.02% (2.5V option). The voltage noise of less than 2µVP-P in the 0.1Hz to 10Hz range and maximum output voltage temperature coefficient of 7 ppm/°C make the ISL21090 ideal for high end applications.
