using a Multiple FeedBack (MFB) circuit arrangement that
reduces sensitivity to passive component variations over
frequency and temperature. For more information regarding
MFB active filter design, please refer to Burr-Brown Appli-
cations Bulletin #34 AB-034 (SBFA001), available from our
web site at http://www.ti.com.
Since the overall system performance is defined by the
quality of the DACs and their associated analog output
circuitry, high-quality audio op amps are recommended for
the active filters. The OPA2353 and OPA2134 dual op amps
from Texas Instruments are recommended for use with the
PCM1741, see Figures 9(a) and 10.
PCB LAYOUT GUIDELINES
A typical PCB floor plan for the PCM1741 is shown in
Figure 12. A ground plane is recommended, with the analog
and digital sections being isolated from one another using a
split or cut in the circuit board. The PCM1741 should be
oriented with the digital I/O pins facing the ground plane
split/cut to allow for short, direct connections to the digital
audio interface and control signals originating from the
digital section of the board.
