FEATURES Wide operating range: 50 µA to 10 mA Initial accuracy: ±0.1% maximum Temperature drift: ±50 ppm/°C maximum Output impedance: 0.5 Ω maximum Wideband noise (10 Hz to 10 kHz): 20 µV rms Operating temperature range: −40°C to +85°C High ESD rating 4 kV human body model 400 V machine model Compact, surface-mount SOT-23 and SC70 packages 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 GENERAL DESCRIPTION The AD15801 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 nonli- nearities in the voltage output temperature characteristics. The AD1580 is stable with any value of capacitive load. 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 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. 1 Protected by U.S. Patent No. 5,969,657.
