AD688ARWZ

The AD688ARWZ series high-precision Voltage Reference with flexible output force and sense terminals. Low tracking error, low initial error and low temperature drift give the AD688ARWZ reference absolute ±10V accuracy performance previously unavailable in monolithic form. The AD688ARWZ uses a proprietary ion-implanted buried zener diode and laser wafer drift trimming of high stability thin-film resistors to provide outstanding performance. The AD688ARWZ includes the basic reference cell and three additional amplifiers. The amplifiers are laser-trimmed for low offset and low drift and maintain the accuracy of the reference. The amplifiers are configured to allow Kelvin connections to the load or boosters for driving long lines or high current loads, delivering the full accuracy of the AD688ARWZ where it is required in the application circuit. The low initial error allows the AD688ARWZ to be used as a system reference in precision measurement applications requiring 12-bit absolute accuracy.
