Precision Bandgap Voltage Reference Provides Exceptional Initial Accuracy at Input Voltages of up to 36V

The device features exceptionally high initial, or ‘start-up,’ accuracy of +/-0.02%. The combination of low current consumption of 930microAmps, typical, and low noise of only 1.9microVpp (0.1Hz to 10Hz), makes the ISL21090 an excellent choice for high-end instrumentation systems up to 24 bits, and for process control, communications and data acquisition systems. It can accept input voltages up to 36V, compared with typical 18V ratings of alternative products.
