DESCRIPTION
The PCM54 and PCM55 family of converters are
parallel input, fully monotonic, 16-bit digital-to-ana-
log converters that are designed and specified for
digital audio applications. These devices employ ul-
tra-stable nichrome (NiCr) thin-film resistors to pro-
vide monotonicity, low distortion, and low differential
linearity error (especially around bipolar zero) over
long periods of time and over the full operating
temperature.
These converters are completely self-contained with a
stable, low noise, internal, zener voltage reference;
high speed current switches; a resistor ladder
network; and a fast settling, low noise output opera-
tional amplifier all on a single monolithic chip. The
converters are operated using two power supplies that

can range from
±5V
(PCM55) to
±12V
(PCM54).
Power dissipation with
±5V
supplies is typically less
than 200mW. Also included is a provision for exter-
nal adjustment of the MSB error (differential linearity
error at bipolar zero, PCM54 only) to further improve
Total Harmonic Distortion (THD) specifications if
desired.
A current output (I
OUT
) wiring option is provided. This
output typically settles to within
±0.006%
of FSR
final value in 350ns (in response to a full-scale change
in the digital input code).
The PCM54 is packaged in 28-pin plastic DIP pack-
age. The PCM55 is available in a 24-lead plastic mini-
flatpak.
