ANALOG DEVICES AD1582WBRTZ-R7 Voltage Reference, Series, 2.498 V to 2.502 V, 50ppm/°C, 0.24%, -40 °C to 125 °C, SOT-23-3

AD1582WBRTZ-R7 is a low-cost, low-power, low-dropout, precision series mode voltage (bandgap) reference. The versatility of this reference makes it ideal for use in battery-powered 3V or 5V 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 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 characteristic. Applications include 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 3V/5V, 8-bit/12-bit data converters.
