Input buffer circuit
The AKD5383 includes full-differential input buffer circuit with an inverted-amp(gain:-10dB). The capacitor of 10nF
between AIN+ /- decreases the clock feed through noise of modulator, and composes a 1st order LPF(fc=360kHz) with
22ohm resistor before the capacitor. This circuit also has a 1st order LPF(fc=370kHz) composed of op-amp. External
analog signal can be fed through the BNC connector or the Cannon connector.

Figure 1. Full-differential input buffer circuit example
1: In case of using the BNC connector
[JP2,JP3,JP4,JP5]: Short
[R11,R18]:
The resistor value of R10 and R19 should be properly selected in order to much the output
impedance of the signal source.
Open
2: In case of using the Cannon connector
[JP2,JP3,JP4,JP5]:
The resistor value of R10, R11, R18 and R19 should be properly selected in order to much the
output impedance of the signal source.

Power supply and Decoupling
VA and VD supplies to the AK5383 are decoupled separately in order to minimize the effect of the digital noise. A system
analog supply is fed to VA. VA and VD lines should be distributed separately from the power unit.
Decoupling capacitors are connected to AK5383 as near as possible, particularly the ceramic capacitor to the VREFL/R
pin.
