DESCRIPTION
The PCM61P is an 18-bit totally pin compatible per-
formance replacement for the popular 16-bit PCM56P.
With the addition of two extra bits, lower max THD+N
(鈥?2dB; PCM61P-K) can be achieved in audio applica-
tions 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.
