Serial Input 18-Bit Monolithic Audio DIGITAL-TO-ANALOG CONVERTER
FEATURES

q 18-BIT MONOLITHIC AUDIO D/A CONVERTER q LOW MAX THD N: 92dB Without External Adjust q 100% PIN COMPATIBLE WITH INDUSTRY STD PCM56P q LOW GLITCH OUTPUT 1mA q CAPABLE OF 8X OVERSAMPLING RATE IN VOUT MODE q COMPLETE WITH INTERNAL REFERENCE AND OUTPUT OP AMP q RELIABLE PLASTIC 16-PIN DIP PACKAGE

DESCRIPTION

The 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 an 18-bit DAC. The PCM61P is capable 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.

NOTES: (1) Binary Two's Complement coding. (2) Ratio of (DistortionRMS + NoiseRMS)/SignalRMS. (3) D/A converter output frequency/signal level. (4) D/A converter sample frequency 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.

This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
