ANALOG DEVICES AD688: High Precision ±10 V Reference Data Sheet (Rev B 2005-03-01-) handbook
The AD688 is a high precision ±10 V tracking reference designed for applications requiring 12-bit absolute accuracy. It utilizes a proprietary ion-implanted buried Zener diode and laser-trimmed thin-film resistors to achieve low initial error and low temperature drift. The device includes three additional amplifiers configured to allow Kelvin connections, enabling it to drive long lines or high current loads while maintaining accuracy.
