The AD680 is a bandgap voltage reference which provides a 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 D/A converters which require an external precision reference. The device is also ideal for A/D converters and, in general, can offer better performance than the standard on-chip references.
Based upon the low quiescent current of the AD680, which that of many incomplete two-terminal references, the AD680 is recommended for low power applications such as hand-held battery equipment.
A temperature output pin is provided on the 8-pin 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 -40°C to +85°C, while the AD680JN is specified for 0°C to +70°C operation. Both the AD680AN and AD680JN are available in 8-pin plastic DIP packages. The AD680AR is specified for operation from -40°C to +85°C, while the AD680JR is specified for 0°C to +70°C operation. Both are available in an 8-pin Small Outline IC (SOIC) package. The AD680JT is specified for 0°C to +70°C operation and is available in a 3-pin TO-92 package.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
