Low Power, Low Cost
2.5 V Reference
AD680 GENERAL DESCRIPTION
The AD680 is a band gap voltage reference that provides a fixed
2.5 V output from inputs between 4.5 V and 36 V. The
architecture of the AD680 enables the reference to be operated
at a very low quiescent current while still realizing excellent dc
characteristics and noise performance. Trimming of the high
stability thin-film resistors is performed for initial accuracy and
temperature coefficient, resulting in low errors over temperature.
The precision dc characteristics of the AD680 make it ideal for
use as a reference for DACs that require an external precision
reference. 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. …
