DESCRIPTION
The PCM58P is a complete, precision 18-bit digitalto-analog converter with ultra-low distortion over a very wide frequency range. The latched serial input data format of the PCM58P is totally based on the widely successful 16-bit PCM56P format (with the addition of two more data bits). The PCM58P features a very low noise and fast settling current output. The PCM58P comes in a 28-pin plastic DIP package. A provision is made for external adjustment of the four MSBs to further improve the PCM58P's specifications, if desired. Applications include very low distortion frequency synthesis and high-end consumer and professional digital audio applications.

DISCUSSION OF SPECIFICATIONS
TOTAL HARMONIC DISTORTION + NOISE The key specification for the PCM58P is total harmonic distortion plus noise. Digital data words are read into the PCM58P at four times the standard audio sampling frequency of 44.1kHz or 176.4kHz such that a sinewave output of 991Hz is realized. For production testing, the output of the DAC goes to a programmable gain amplifier to provide gain at lower signal output test levels and then through a 20kHz low pass filter before being fed into an analog type distortion analyzer. Figure 1 shows a block diagram of the production THD+N test setup.
