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.
