The LH0070 and LH0071 are precision, three terminal, voltage references consisting of a temperature compensated zener diode driven by a current regulator and a buffer amplifier. The devices provide an accurate reference that is virtually independent of input voltage, load current, temperature and time. The LH0070 has a 10.000V nominal output to provide equal step sizes in BCD applications.
The LH0071 has a 10.240V nominal output to provide equal step sizes in binary applications. The output voltage is established by trimming ultra-stable, low temperature drift, thin film resistors under actual operating circuit conditions. The devices are shortcircuit proof in both the current sourcing and sinking directions.
The LH0070 and LH0071 series combine excellent long term stability, ease of application, and low cost, makingthem ideal choices as reference voltages in precision D to A and A to D systems.
