The parts are available in 8-lead SOIC, PDIP, CERDIP, and TO-99 packages, as well as 20-terminal LCC packages (883 only), furthering the parts’ usability in both standard and high stress applications. With an external buffer and a simple resistor network, the TEMP terminal can be used for temperature sensing and approximation. A TRIM terminal is also provided on the device for fine adjustment of the output voltage. The small footprint, wide supply range, and application versatility make the REF0x series of references ideal for general- purpose and space-constrained applications. Newer designs should use the ADR0x series of references, which offer higher accuracy and temperature stability over a wider operating temperature range, while maintaining full pin- for-pin compatibility with the REF0x series. This data sheet applies to commercial-grade products only. Contact sales or visit analog.com for military-grade (883) data sheets. Table 1.
