5. POWER SUPPLY CIRCUITRY
Power is supplied to the evaluation board by four binding posts (GND, +5V, +12V, and -12V), see Figure 53 . The
‘+5V’ terminal supplies VA and the rest of the +5-V circuitry on the board. The +3.3-V circuitry is powered from a
regulator. The +2.5 volts required for VD is also provided from an on-board regulator. The +5-V supply should be
set within the recommended values for VA stated in the CS4385 datasheet.
WARNING: Refer to the CS4385 datasheet for maximum allowable voltage levels. Operation outside of this range
can cause permanent damage to the device.
6. GROUNDING AND POWER SUPPLY DECOUPLING
As with any high-performance converter, the CS4385 requires careful attention to power supply and grounding ar-
rangements to optimize performance. Figure 44 details the connections to the CS4385 and Figures 54 , 55 , and 56
show the component placement and top and bottom layout. The decoupling capacitors are located as close to the
CS4385 as possible. Extensive use of ground plane fill in the evaluation board yields large reductions in radiated
noise.
7. ANALOG OUTPUT FILTERING
The analog output on the CDB4385 has been designed according to the CS4385 datasheet. This output circuit in-
cludes an active 2-pole, 50-kHz filter which utilizes the multiple-feedback topology.
