Description
The ISL71010B25 is an ultra-low noise, high DC accuracy precision voltage reference with a wide input voltage range from 4V to 30V. The ISL71010B25 uses the dielectrically isolated PR40 process to achieve 1.9μVP-P noise at 0.1Hz to 10Hz with an initial voltage accuracy of ±0.05%. The ISL71010B25 offers a 2.5V output voltage with 10ppm/°C temperature coefficient and also provides excellent line and load regulation. The device is offered in an 8 Ld SOIC package. The ISL71010B25 is ideal for high-end instrumentation, data acquisition, and processing applications requiring high DC precision where low noise performance is critical.
