The REF01 / REF02 / REF03 series of precision voltage references provide a stable 10.0 V, 5.0 V, or 2.5 V output with minimal change in response to variations in supply voltage, ambient temperature or load conditions. The devices are available in 8-lead SOIC, PDIP, CERDIP, and TO-99 packages, as well as 20-terminal LCC packages (883 only), furthering the usability of the devices 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 ADR01 / ADR02 / ADR03 / ADR06 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 REF01 / REF02 / REF03 series. This data sheet applies to commercial-grade products only.

The REF19x series precision band gap voltage references use a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors to achieve a very low temperature coefficient and high initial accuracy.The REF19x series is made up of micropower, low dropout voltage (LDV) devices, providing stable output voltage from supplies as low as 100 mV above the output voltage and consuming less than 45 μA of supply current. In sleep mode, which is enabled by applying a low TTL or CMOS level to the SLEEP pin, the output is turned off, and supply current is further reduced to less than 15 µA.The REF19x series references are specified over the extended industrial temperature range (−40°C to +85°C), with typical performance specifications over −40°C to +125°C for applications such as automotive.All electrical grades are available in an 8-lead SOIC_N package; the PDIP and TSSOP packages are available only in the lowest electrical grade. Products are also available in die form.APPLICATIONS Portable instruments ADCs and DACs Smart sensors Solar-powered applications Loop current-powered instruments
