OPTION
This converter is completely self-contained with a
stable, low noise, internal zener voltage reference;
high speed current switches; a resistor ladder net-
work; and a fast settling, low noise output operational
amplifier all on a single monolithic chip. The
converters are operated using two power supplies that
can range from
±5V
to
±12V.
Power dissipation with
±5V
supplies is typically less than 200mW. Also
included is a provision for external adjustment of the
MSB error (differential linearity error at bipolar zero)
to further improve total harmonic distortion (THD)
specifications if desired. Few external components
are necessary for operation, and all critical
specifications are 100% tested. This helps assure the
user of high system reliability and outstanding overall
system performance.
The PCM56 is packaged in a high-quality 16-pin
molded plastic DIP package or SOIC and has passed
operating life tests under simultaneous high-pressure,
high-temperature, and high-humidity conditions.

DESCRIPTION
The PCM56 is a state-of-the-art, fully monotonic,
digital-to-analog converter that is designed and
specified for digital audio applications. This device
employs ultra-stable nichrome (NiCr) thin-film
resistors to provide monotonicity, low distortion, and
low differential linearity error (especially around
bipolar zero) over long periods of time and over the
full operating temperature.
