GENERAL DESCRIPTION

The AD1580 is a low cost, two-terminal (shunt), precision

bandgap reference. It provides an accurate 1.225 V output for

input currents between 50 A and 10 mA.

The AD1580’s superior accuracy and stability is made possible

by the precise matching and thermal tracking of on-chip

components. Proprietary curvature correction design techniques

have been used to minimize the nonlinearities in the voltage

output temperature characteristics. The AD1580 is stable with

any value of capacitive load.

The low minimum operating current makes the AD1580 ideal

for use in battery powered 3 V or 5 V systems. However, the

wide operating current range means that the AD1580 is

extremely versatile and suitable for use in a wide variety of high

current applications.

The AD1580 is available in two grades, A and B, both of which

are provided in an SOT-23 package, the smallest surface mount

package available on the market. Both grades are specified over

the industrial temperature range of –40 C to +85 C.

TARGET APPLICATIONS

1. Portable, Battery-Powered Equipment:

2. Computer Workstations

3. Smart Industrial Transmitters

4. PCMCIA Cards.

5. Automotive.

6. 3 V/5 V 8–12-Bit Data Converters.
