GENERAL DESCRIPTION

The AD588 represents a major advance in the state-of-the-art

in monolithic voltage references. Low initial error and low tem-

perature 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 at low cost.

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 main-

tain the accuracy of the reference. The amplifiers are configured

to allow Kelvin connections to the load and/or boosters for driv-

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

of the AD588 where it is required in the application circuit.

PRODUCT HIGHLIGHTS

1. 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 thus does not increase the temperature drift.

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, and the low

drift allows compensation for the drift of other components in

2. Output noise of the AD588 is very low—typically 6 µV p-p.

A pin is provided for additional noise filtering using an exter-

nal capacitor.

system. Manual system calibration and the cost of periodic

3. A precision 5 V tracking mode with Kelvin output connec-

tions 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.

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 autocalibration software.

4. Pin strapping capability allows configuration of a wide vari-

ety 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.

The AD588 is available in four versions. The AD588JQ and

AD588KQ and grades are packaged in a 16-lead CERDIP and

are specified for 0°C to 70°C operation. AD588AQ and BQ

grades are packaged in a 16-lead CERDIP and are specified for

the –25°C to +85°C industrial temperature range.
