Part Number: OPA1632 Other Parts Discussed in Thread: PCM4222 Hello TI team, We plan to use the OPA1632 as an input buffer circuit for an ADC. The circuitry for this buffer will be according to figure 50 in the PCM4222 datasheet. The question is how can…
Part Number: OPA1632 Tool/software: Hi Tech Support, I am in the middle of bench testing this circuit using the OPA1632 chip. I am configuring it as a single ended analog input with a differential output. When I put a 3V test voltage on the input side…
Part Number: OPA1632 Other Parts Discussed in Thread: TPA3251 , , TPA3251EVM , TPA3255 , TPA3250 , OPA1637 , OPA1633 Tool/software: Hi,
I have a question regarding the correct way to tie the grounds of the source input and the OPA1632 front end as shown…
Part Number: OPA1632 Tool/software: Hi,
I'm testing a simple test circuit with this chip. It is a differential amp.
Input resistors are 5.6k and feedback resistors are 11.3k.
Both inputs and outputs are isolated with capacitors, so no DC current…
Part Number: PCM4204 Other Parts Discussed in Thread: , OPA1632 Tool/software: Hi,
I am implementing a circuit design that closely follows the analog front-end of the PCM4204EVM, including the op-amp and buffer stages. The only variations in my implementation…
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…
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…
Part Number: OPA1632 Tool/software: In TI book op amps for everyone , chapter 18 Designing Low voltage op circuits - in section 18.7 for single supply circuit design it is given that equation of straight line is to be followed. What should be approach…
Part Number: OPA1632 Other Parts Discussed in Thread: TINA-TI
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 Other Parts Discussed in Thread: OPA1633 , OPA1622 Tool/software: The circuit of OPA1632 is as shown in the attached schematic.
Right now, we have mounted only the first stage, U29 and its circuit. The capacitors C94 to C97 are…
