The AD6801 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 DA Cs that require an external precision reference. The device is also ideal for Ad Cs 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. The AD680 is available in five grades. The AD680AN is specified for operation from -40oC to +85oC, while the AD680JN is specified for 0oC to 70oC operation. Both the AD680AN and AD680JN are available in 8-lead PDIP packages. The AD680AR is specified for operation from -40oC to +85oC, while the AD680JR is specified for 0oC to 70oC operation. Both are available in 8-lead SOIC packages. The AD680JT is specified for 0oC to 70oC operation and is available in a 3-pin TO-92 package. 1 Protected by U.S. Patent Nos. 4,902,959; 4,250,445; and 4,857,862.
