PCM61P
Serial Input 18-Bit Monolithic Audio
DIGITAL-TO-ANALOG CONVERTER
DESCRIPTION
The PCM61P is an 18-bit totally pin compatible performance replacement for the popular 16-bit PCM56P.
With the addition of two extra bits, lower max THD+N
(–92dB; PCM61P-K) can be achieved in audio applications already using the PCM56P. The PCM61P is
complete with internal reference and output op amp and
requires no external parts to function as an 18-bit DAC.
The PCM61P is capable of an 8-times oversampling
rate (single channel) and meets all of its specifications
without an external output deglitcher.
The PCM61P comes in a small, reliable 16-pin plastic
DIP package that has passed operating life tests under
simultaneous high temperature, high humidity and high
pressure testing.

sample frequency (4 x 44.1kHz; 4 times oversampling). (5) Bipolar zero, using A-weighted filter. (6) This is the combined drift error due to gain, offset, and linearity over
temperature. (7) All positive and all negative supply pins must be tied together respectively.
