Part Number: OPA1632 Other Parts Discussed in Thread: OPA1633 , TPA3244 Tool/software: The datasheet unfortunately is not clear about this. Samacsys says that the SOIC8 version of the OPA1632 does not have a power pad. Is this correct? Thanks in advance…
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…
Part Number: OPA1632 Other Parts Discussed in Thread: OPA1655 Tool/software: Hello !
I get different p-p amplitude from the outputs.(check the red remarks 1860 vs 2120mV)
I have checked following:
1) checked and doublechecked all resistors - nope
2…
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.

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…
