LH0070 Series Precision BCD Buffered Reference
LH0071 Series Precision Binary Buffered Reference
General Description
The LH0070 and LH0071 are precision three terminal volt-
age references consisting of a temperature compensated
zener diode driven by a current regulator and a buffer ampli-
fier The devices provide an accurate reference that is virtu-
ally 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 operat-
ing 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 making
Equivalent Schematic
Typical Applications
relatively small and constant with temperature and input voltage For the circuit shown supply sensitivities are degraded slightly to 0 01% V change in V
for changes in V
An additional temperature drift of 0 0001% C is added due to the variation of supply current with temperature of the LH0070 and LH0071 Sensitivity to the
value of R1 R2 and R3 is less than 0 001% %
Note The output of the LH0070 and LH0071 may be adjusted to a precise voltage by using the above circuit since the supply current of the devices is
