Therefore input level for this board is +0.51dBV(=3.0Vpp)+6.02dB = +6.53dBV = 6.00Vpp = 2.12Vrms. 2) S/N of op-amp circuit (Theory: BW=20k+A) Non-inverting amp is implemented on board. The output noise level of op-amp circuit is -126.01dBV = -132.54dB (0dB=+6.53dBV). S/N of ADC is 103.6dB (measurement). Therefore total S/N of op-amp circuit and ADC is 103.59dB (measurement: 103.6dB). 2005/11 ASAHI KASEI [AKD4626A-B] Consideration for analog output circuit 3.0Vpp 6.0Vpp 22u NJM4580 + 4.7k 220 Signal 330p AK4626A ROUT1 28 LOUT1 27 ROUT2 26 LOUT2 25 ROUT3 24 LOUT3 23 Same circuit Same circuit 10k 4.7k Same circuit Same circuit Same circuit 1) Frequency response of HPF The HPF is implemented on board to cancel the DC offset of analog output of AK4626A. Frequency response of 1st-order HPF | Amplitude |2 = 1/{1+(fc/f)2}; fc=1/2RC=0.7Hz@R=10k,C=22u fin 20Hz Frequency Response -0.006dB 2) Gain, S/N and frequency response of op-amp circuit 1st-order filter with non-inverting amp is implemented on board to double the analog output level and attenuate out-of-band noise. a) Gain The gain is 1+4.7k/4.7k = +6.02dB. Therefore the output level of this board is 0.51dBV(=3.0Vpp) + 6.02dB = 6.53dBV = 6.00Vpp = 2.12Vrms. b) S/N (Theory: BW=20k+A) The output noise level of non-inverting amp -110.36dBV = -116.89dB (0dB=6.53dBV) S/N of DAC is 106.3dB (measurement) Therefore total S/N of op-amp circuit and DAC is 105.94dB (measurement: 106.1dB). 2005/11 ASAHI KASEI [AKD4626A-B] c) Frequency response of filter Frequency response of the 1st-order filter | Amplitude |2 = K*{1+(f/fc2)2}/{1+(f/fc1)2}; K = 1+4.7k/4.7k = 2, fc1 = 1/2RC = 102.7kHz@R=4.7k,C=330p, fc2 = K*fc1 = 205.3kHz Frequency response referenced to output level of this board is as following table: fin DC 20kHz 40kHz 80kHz Frequency Response 0dB -0.121dB -0.452dB -1.448dB 145kHz -3dB -6dB If the frequency response of filter influences the system, 1st-order LPF is also available as the following figure: 3.0Vpp LPF 22u NJM4580 + 4.7k 220 Signal 3300p 6.0Vpp AK4626A ROUT1 28 LOUT1 27 ROUT2 26 LOUT2 25 ROUT3 24 LOUT3 23 Same circuit Same circuit 10k 4.7k Same circuit Same circuit Same circuit Frequency response of this LPF | Amplitude |2 = 1/{1+(f/fc)2}; fc = 1/2RC = 219kHz@R=220,C=3300p Frequency response referenced to output level of this board is as following table: fin DC 20kHz 40kHz 80kHz Frequency Response 0dB -0.036dB -0.142dB -0.543dB 219kHz -3dB -dB The total frequency response of this board is sum of the external filter and internal LPF of AK4626A. These filters are effective to attenuate the high frequency noise since some measurement units is sensitive for out-of-band noise. 2005/11 ASAHI KASEI [AKD4626A-B] 2.
