General Description

The AD688 is a high precision ±10 V tracking reference.

Low tracking error, low initial error, and low temperature drift give the AD688 reference absolute ±10 V accuracy performance previously unavailable in monolithic form.

The AD688 uses a proprietary ion-implanted buried Zener diode, and laser wafer drift trimming of high stability thin-film resistors to provide outstanding performance.

Key Features

  • ±10 V tracking outputs Kelvin connections Low tracking error: 1.5 mV Low initial error: 2.0 mV Low drift: 1.5 ppm/°C Low noise: 6 μV p-p Flexible output force and sense terminals High impedance ground sense Wide body SOIC and CERDIP packages.
