n 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.
