AK4620B Evaluation board Rev.1
GENERAL DESCRIPTION The AKD4620B-B is an evaluation board for the AK4620B, the 24Bit A/D & D/A converter. The AKD4620B-B can evaluate A/D converter and D/A converter separately in addition to loopback mode (A/DD/A). The AKD4620B-B also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. Ordering guide

Analog Input Buffer Circuit 1. Differential Input Mode The AK4620B can accept input voltages from AGND to VA. The input signal range scales with the VREF voltage and is nominally 2.82Vpp (VREF = 5V). Figure 3 shows an input buffer circuit example. This is a fully differential input buffer circuit with an inverted amplifier (fc=370KHz,gain: -10dB). The capacitor of 10nF between AINL+/- (AINR+/-) decreases the clock feedthrough noise of the modulator, and composes a 1st order LPF (fc=360kHz) with a 22 resistor before the capacitor.

Analog Output Buffer Circuit The differential output circuit(2nd order LPF,fc=182KHz,Q=0.637,G=+3.9dB) and LPF(1st order LPF, fc=284KHz, G=-0.84dB) is implemented on board. The differential outputs of AK4620B is buffered by non-inverted circuit and output via Cannon connector (differential output). LPF adds differential outputs. NJM5534D is used for op-amp on this board that has low noise and high voltage torelance characteristics. Analog signal is output via BNC connectors on the board. The output level is about 2.8Vrms (typ@VREF=5.0V) by BNC.
