FEATURES
Low quiescent current at 250 μA max Laser trimmed to high accuracy 2.5 V ± 5 mV max (AN, AR grades) Trimmed temperature coefficient 20 ppm/°C max (AN, AR grades) Low noise at 8 μV p-p from 0.1 Hz to 10 Hz 250 nV/√Hz wideband Temperature output pin (N, R packages) Available in three package styles 8-lead PDIP, 8-lead SOIC, and 3-pin TO-92 GENERAL DESCRIPTION
Trimming of the high stability thin-film resistors is performed for initial accuracy and temperature coefficient, resulting in low errors over temperature. The device is also ideal for ADCs and, in general, can offer better performance than the standard on-chip references. Based upon its low quiescent current, which rivals that of many incomplete 2-terminal references, the AD680 is recommended for low power applications, such as hand-held, battery-operated equipment. A temperature output pin is provided on the 8-lead package versions of the AD680. The temperature output pin provides an output voltage that varies linearly with temperature and allows the AD680 to be configured as a temperature transducer while providing a stable 2.5 V output.
