GENERAL DESCRIPTION
The AD15801 is a low cost, 2-terminal (shunt), precision band
gap reference. It provides an accurate 1.225 V output for input
currents between 50 μA and 10 mA.
The superior accuracy and stability of the AD1580 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 nonli-
nearities 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 the SOT-23 and SC70 packages, the smallest
surface-mount packages available. Both grades are specified
over the industrial temperature range of −40°C to +85°C.

1 Specification is for device in free air at 25°C, SOT-23 package. θJA = 300°C/W.
2 The human body model is a 100 pF capacitor discharged through 1.5 kΩ. For
the machine model, a 200 pF capacitor is discharged directly into the device.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

AD1580
The AD1580 is ideal for creating the reference level to use with 12-bit
multiplying DACs, such as the AD7943, AD7945, and AD7948.
In the single-supply bias mode (see Figure 26), the impedance
seen looking into the IOUT2 terminal changes with DAC code. If
the AD1580 drives IOUT2 and AGND directly, less than 0.2 LSBs
of additional linearity error results. The buffer amp eliminates
any linearity degradation that could result from variations in
the reference level.
