AD588:  High Precision Voltage Reference Microcomputer

Product Description

The AD5881 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

  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 so does not increase the temperature drift.
  2. 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.
  3. 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.
  4. 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.
