Hi Alec,
Thank you for looking into it. The OPA1632 is not configured as having a single L and single R channel. Two OPA's are used, one per channel since it's a SE to diff converter here. Therefore, the configuration issue for grounding remains the same…
Hi Alec,
The issue in the circuit is resolved. The problem was, in the circuit the connections to vout+ and vout- were interchanged.
Thanks for the support.
Regards,

My circuit consist of 3 OPA1632 Opamps, 1 for Bandpass filter and 2 opamps for gain. The output SINAD Of Audio Analyzer is 80 dB . But the after opamps the sinad is 55 dB, THD is less than…
Part Number: OPA1632 Hi Team,
The audio DAC is designed using the OPA1632 to design the LPF circuit, which is placed after the IV circuit as shown in the following figure:
The circuit is simulated and has no problem, but practical testing found that…

Part Number: OPA1632 Other Parts Discussed in Thread: TIDA-01359 Hi
1. May I ask whether the OPA1632 is OK if it is used in MIC amplification?
2. SPEC mentioned that the Supply voltage (V+ – V-) has Dual & Single. Does it mean that I can only use V+…
Hi Roy,
Attached is a PowerPoint presentation that outlines our noise measurement process. Take special attention to slide 18.
