Precision 2.5 V, 5.0 V, and 10.0 V
Voltage References
REF01/REF02/REF03
GENERAL DESCRIPTION
FEATURES
High output accuracy
The REF0x 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 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.
REF01: 10.0 V, 0.3ꢀ maximum
REF02: 5.0 V, 0.3ꢀ maximum
REF03: 2.5 V, 0.6ꢀ maximum
Adjustable output: 3ꢀ minimum
Excellent temperature stability
REF01: 8.5 ppm/°C maximum
REF02: 8.5 ppm/°C maximum
REF03: 50 ppm/°C maximum
Low noise
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.
REF01: 30 μV p-p typical
REF02: 15 μV p-p typical
The small footprint, wide supply range, and application
versatility make the REF0x series of references ideal for general-
purpose and space-constrained applications.
REF03: 6 μV p-p typical
High supply voltage range: up to 36 V maximum
Low supply current: 1.4 mA maximum
High load-driving capability: 10 mA maximum
Temperature output function
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.
