Overview
Data Sheet FEATURES Low drift: 1.
5 ppm/°C Low initial error: 1 mV Pin programmable output +10 V, +5 V, ±5 V tracking, −5 V, −10 V Flexible output force and sense terminals High impedance ground sense 16-lead SOIC package and 16-lead CERDIP MIL-STD-883-compliant versions available 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 ...
