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
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.
