... CD players. PCM69A digital offset occurs at bit 4, making it an excellent choice for digital musical instruments and audio DSP. Both PCM67 and PCM69A operate from a single +5V supply. The low power consumption and small size (16- pin PDIP or 20-pin SOIC) make these converters ideal for a variety of digital audio applications ...

... THE RELATIONSHIP OF V AND I/V OUT COM The output current range of PCM67 and PCM69A is 0mA to 1.2mA as shown in Table 1. In the typical application, the non-inverting input of the external I/V op amp is connected to the V and PCM69A. Accordingly, the output voltage level at FSR after I/V conversion is V voltage (+3 ...

THEORY OF OPERATION Digital converters in audio systems have traditionally utilized a laser-trimmed, current-source DAC architecture. Unfortu- nately, this type of technology suffers from the problems inherent in switching widely varying current levels. Design improvements have helped, but DACs of ...
