The LT1019 is a third generation bandgap voltage reference utilizing thin film technology and a greatly improved curvature correction technique.
The LT1019 is a precision voltage reference utilizing thin film technology and curvature correction to achieve high yields and tight initial tolerance. It can operate in both series and shunt modes, allowing it to sink or source up to 10mA for use in positive and negative output applications without external components.
| Output Voltage Tolerance (Typ) | 0.05% |
|---|---|
| Temperature Coefficient | 3ppm/°C Typical |
| Output Impedance | = 0.02Ω |
| Available Voltages | 2.5V, 4.5V, 5V, and 10V |
| Sourcing/Sinking Current | Up to 10mA |
It is a direct replacement for most bandgap references including AD580, AD581, REF-01, REF-02, MC1400, MC1404 and LM168.
The LT1019 specifies a thermal regulation of 0.5ppm/mW caused by die temperature gradients.
