AD688BQ информация о продукте

The AD688BQ is a high precision ±10 V tracking reference. Low tracking error, low initial error and low temperature drift give the AD688BQ reference absolute ±10 V accuracy performance previously unavailable in monolithic form. The AD688BQ 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 AD688BQ 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 and/or boosters for driving long lines or high current loads, delivering the full accuracy of the AD688BQ where it is required in the application circuit.

The low initial error allows the AD688BQ to be used as a system reference in precision measurement applications requiring 12-bit absolute accuracy. In such systems, the AD688BQ can provide a known voltage for 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 AD688BQ and calibration software.

The AD688BQ is available in three versions. The AD688AQand BQ grades are packaged in 16-pin cerdip (0.3") packages and are specified for operation from -40°C to +85°C. The AD688SQ grade is specified for operation from -55°C to +125°C.
