GENERAL DESCRIPTION

The

AD588

represents a major advance in state-of-the-art

monolithic voltage references. Low initial error and low

temperature drift give the

AD588

absolute accuracy performance

previously not available in monolithic form. The

AD588

uses a

proprietary ion-implanted, buried Zener diode and laser-wafer

drift trimming of high stability thin film resistors to provide

outstanding performance.

The

AD588

includes the basic reference cell and three additional

amplifiers that provide pin programmable output ranges. The

amplifiers are laser trimmed for low offset and low drift to maintain

the accuracy of the reference. The amplifiers are configured to

allow Kelvin connections to the load and/or boosters for driving

long lines or high current loads, delivering the full accuracy of

the

AD588

where it is required in the application circuit.

The low initial error allows the

AD588

to be used as a system

reference in precision measurement applications requiring

12-bit absolute accuracy. In such systems, the

AD588

can provide a

known voltage for system calibration in software. The low drift

also allows compensation for the drift of other components in a

system. Manual system calibration and the cost of periodic

recalibration can, therefore, be eliminated. Furthermore, the

mechanical instability of a trimming potentiometer and the

potential for improper calibration can be eliminated by using

the

AD588

in conjunction with auto calibration software.

The

AD588

is available in seven versions. The

AD588JQ

and

AD588KQ

are packaged in a 16-lead CERDIP and are specified

for 0°C to +70°C operation. The

AD588AQ

and

AD588BQ

are

packaged in a 16-lead CERDIP, and the

AD588ARWZ

is packaged

in a 16-lead SOIC, and they are specified for the −25°C to +85°C

industrial temperature range. The ceramic

AD588TE

and

AD588TQ

grades are specified for the full military/aerospace

temperature range.

PRODUCT HIGHLIGHTS

The

AD588

offers 12-bit absolute accuracy without any

user adjustments. Optional fine-trim connections are

provided for applications requiring higher precision. The

fine trimming does not alter the operating conditions of

the Zener or the buffer amplifiers, and so does not increase

the temperature drift.

Output noise of the

AD588

is very low, typically 6 µV p-p.

A pin is provided for additional noise filtering using an

external capacitor.

A precision ±5 V tracking mode with Kelvin output

connections is available with no external components.

Tracking error is less than 1 mV, and a fine trim is available

for applications requiring exact symmetry between the

+5 V and −5 V outputs.

Pin strapping capability allows configuration of a wide

variety of outputs: ±5 V, +5 V, +10 V, −5 V, and −10 V dual

outputs or +5 V, −5 V, +10 V, and −10 V single outputs.
