These designs are available as three-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 may 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 is made possible by 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.
These series mode devices (AD1582/AD1583/AD1584/AD1585) source or sink up to 5 mA of load current and operate efficiently with only 200 mV of required headroom supply. This family draws a maximum 70 A of quiescent current with only a 1.0 A/V variation with supply voltage. The advantage of these designs over conventional shunt devices is extraordinary. Valuable supply current is no longer wasted through an input series resistor, and maximum power efficiency is achieved at all input voltage levels. The AD1582, AD1583, AD1584, and AD1585 are available in three grades, A, B, and C, and are provided in a tiny footprint, the SOT-23. All grades are specified over the industrial temperature range of 40°C to +125°C.
