AD1580:  1.2 V Micropower, Precision Shunt Voltage Reference

Product Description

The AD1580* is a low cost, 2-terminal (shunt), precision band gap reference. It provides an accurate 1.225 V output for input currents between 50 μA and 10 mA.

The superior accuracy and stability of the AD1580 is made possible by the precise matching and thermal tracking of on-chip components. Proprietary curvature correction design techniques have been used to minimize the nonlinearities in the voltage output temperature characteristics. The AD1580 is stable with any value of capacitive load.

The low minimum operating current makes the AD1580 ideal for use in battery-powered 3 V or 5 V systems. However, the wide operating current range means that the AD1580 is extremely versatile and suitable for use in a wide variety of high current applications.

The AD1580 is available in two grades, A and B, both of which are provided in the SOT-23 and SC70 packages, the smallest surface-mount packages available. Both grades are specified over the industrial temperature range of −40°C to +85°C.

Applications

  • Portable, battery-powered equipment
    Cellular phones, notebook computers, PDAs, GPSs, and DMMs
  • Computer workstations
  • Suitable for use with a wide range of video RAMDACs
  • Smart industrial transmitters
  • PCMCIA cards
  • Automotive
  • 3 V/5 V, 8-bit to 12-bit data converters

* Protected by U.S. Patent No. 5,969,657; other patents pending.
