The AD588JQ is a Multiple Output High Precision Dual-tracking Reference that 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. It uses a proprietary ion-implanted, buried Zener diode and laser-wafer drift trimming of high stability thin film resistors to provide outstanding performance. The reference 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.
