The AD588TQ/883B 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 AD588TQ/883B where it is required in the application circuit.
The low initial error allows the AD588TQ/883B to be used as a system reference in precision measurement applications requiring 12-bit absolute accuracy. In such systems, the AD588TQ/883B 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 AD588TQ/883B in conjunction with auto calibration software.
The AD588TQ/883B 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.
