AD588* High Precision Voltage Reference FEATURES Low Drift: 1.5 ppm/ C Low Initial Error: 1 mV Pin Programmable Output: +10 V, +5 V, +65 V Tracking, –5 V, –10 V Flexible Output Force and Sense Terminals High Impedance Ground Sense Machine lnsertable DIP Packaging MIL-STD-883 Compliant Versions Available FUNCTIONAL BLOCK DIAGRAM R3 RB R1 R2 R4 R5 R6 GAIN ADJ GND SENSE +IN GND SENSE –IN VLOW BAL ADJ VCT A4 IN –VS +VS A4 OUT FORCE A4 OUT SENSE A3 OUT FORCE A3 OUT SENSE A3 IN VHIGH NOISE REDUCTION A1 A4 AD588 A3 A2 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. 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 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 autocalibration software. 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. *Protected by Patent Number 4,644,253. 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. 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. 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. 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. |
