ANALOG DEVICES LT1634ACS8-1.25#PBF Voltage Reference, 10ppm/°C, 1.25V, 0.05%, Shunt, SOIC-8, 0°C to 70°C

LT®1634 is a micropower, precision, shunt voltage reference. The bandgap reference uses trimmed precision thin film resistors. Advances in design, processing and packaging techniques guarantee 10µA operation and low temperature cycling hysteresis. The LT1634 does not require an output compensation capacitor, but is stable with capacitive loads. Low dynamic impedance makes the LT1634 reference easy to use from unregulated supplies. The LT1634 reference can be used as a high performance upgrade to the LM185/LM385, LT1004 and LT1034 where lower power and guaranteed temperature drift is required. Typical applications are portable meters, precision regulators, A/D and D/A converters, calibrators.
