AD1584

Data Sheet 2.5 V to 5.0 V Micropower, Precision Series Mode Voltage References AD1582/AD1583/AD1584/AD1585 FEATURES Series reference (2.5 V, 3 V, 4.096 V, 5 V) Low quiescent current: 70 µA maximum Current output capability: ±5 mA Wide supply range: VIN = VOUT + 200 mV to 12 V Wideband noise (10 Hz to 10 kHz): 50 µV rms Specified temperature range: −40°C to +125°C Compact, surface-mount SOT-23 package Qualified for automotive applications APPLICATIONS Portable, battery-powered equipment; for example, notebook computers, cellular phones, pagers, PDAs, GPSs, and DMMs Computer workstations; suitable for use with a wide range of video RAMDACs Smart industrial transmitters PCMCIA cards Automotive Hard disk drives 3 V/5 V, 8-bit/12-bit data converters GENERAL DESCRIPTION The AD1582/AD1583/AD1584/AD1585 are low cost, low power, low dropout, precision band gap references. These designs are available as 3-terminal (series) devices and are packaged in the compact SOT-23, 3-lead surface-mount package. The versatility of these references makes them ideal for use in battery-powered 3 V or 5 V systems where there can be wide variations in supply voltage and a need to minimize power dissipation. The superior accuracy and temperature stability of the AD1582/ AD1583/AD1584/AD1585 result from the precise matching and thermal tracking of on-chip components. Patented temperature drift curvature correction design techniques minimize the nonlinearities in the voltage output temperature characteri...
