The PCM54 and PCM55 family of converters are
parallel input, fully monotonic, 16-bit digital-to-analog
converters that are designed and specified for
digital audio applications. These devices employ 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.
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 operational
amplifier all on a single monolithic chip. The
converters are operated using two power supplies that
can range from Â±5V (PCM55) to Â±12V (PCM54).
Power dissipation with Â±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, PCM54 only) to further improve
Total Harmonic Distortion (THD) specifications if
desired.
A current output (IOUT) wiring option is provided. This
output typically settles to within Â±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 package.
The PCM55 is available in a 24-lead plastic miniflatpak.
