AD1580-1.2 V Micropower, Precision Shunt Voltage Reference

1.2 V Micropower, Precision Shunt Voltage Reference- Wide operating range: 50 µA to 10 mA- Initial accuracy: ±0.1% maximum- Temperature drift: ±50 ppm/°C maximum- Output impedance: 0.5 ? 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 packagesThe AD15801The 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.
