GENERAL DESCRIPTION

The AD1582, AD1583, AD1584, and AD1585 are a family of low

cost, low power, low dropout, precision band gap references.

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.

3. Smart industrial transmitters

4. PCMCIA cards

5. Automotive

6. Hard disk drives

7. 3 V/5 V, 8-bit/12-bit data converters

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.

SHUNT REFERENCE

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 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, 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 tem-

perature range of –40°C to +125°C.
