Product overview
Overview
General Description
The REF01 and REF02 are precision voltage references that are pretrimmed to within ±3% of +10V and +5V, respectively. Both references feature excellent temperature stability (as low as 8.5 ppm/°C worst case), low current drain, and low noise.
Features
♦Pretrimmed to +5V, +10V ±0.3%
♦Excellent Temperature Stability: 3ppm/°C
♦Low Noise: 10µVp-p (REF02)
♦Low Supply Current: 1.4mA max
♦Short-Circuit Proof
♦Linear Temperature Transducer O/P (REF02)Applications A to D Converters D to A Converters Digital Voltmeters Voltage Regulators Threshold Detectors
