LT1019 Precision Reference FEATURES s s s s s s s s s s s DESCRIPTIO Tight Initial Output Voltage: < 0.05% Ultralow Drift: 3ppm/°C Typical Series or Shunt Operation Curvature Corrected Ultrahigh Line Rejection: ≈ 0.5ppm/V Low Output Impedance: ≈ 0.02Ω Plug-In Replacement for Present References Available at 2.5V, 4.5V, 5V, and 10V 100% Noise Tested Temperature Output Industrial Temperature Range in SO-8 The LT ®1019 is a third generation bandgap voltage reference utilizing thin film technology and a greatly improved curvature correction technique. Wafer level trimming of both reference and output voltage combines to produce units with high yields to very low TC and tight initial tolerance of output voltage. The LT1019 can both sink and source up to 10mA and can be used in either the series or shunt mode. This allows the reference to be used for both positive and negative output voltages without external components. Minimum input/ output voltage is less than 1V in the series mode, providing improved tolerance of low line conditions. The LT1019 is available in four voltages: 2.5V, 4.5V, 5V and 10V. It is a direct replacement for most bandgap references presently available including AD580, AD581, REF-01, REF-02, MC1400, MC1404 and LM168.
