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 characteristic.
The
AD1582/AD1583/AD1584/AD1585
series mode devices
source or sink up to 5 mA of load current and operate efficiently
with only 200 mV of required headroom supply. These parts
draw a maximum 70 μA of quiescent current with only a
1.0 μA/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/AD1585
are available in two
grades, A and B, 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.
