GENERAL DESCRIPTION
CERTIFICATE OF CALIBRATION
The DAC1136/1138 are complete self-contained current or
voltage output modular digital-to-analog converters with
resolutions and accuracies of 16 and 18 bits.
Each DAC1138 has been calibrated with equipment and
methods that are traceable to the National Bure:m of Stand-
ards (NBS). A Certificate of Performance is sent with each

with state-of-the-art steering switches to produce a very linear
output. Inputs to these converters are compatible with TTL
levels. The converters have a current outpu t of -2mA full scale.
A voltage output can be obtained by connecting the internal

The DACI136/1138 are available on Card-Mounted Assemblies.
In this configuration, selectable options include: input codes,
output amplifiers, and a high speed transient-suppressing
