Part Number: OPA375 Other Parts Discussed in Thread: LMV1012
Hi, Ti.
I constructed an electret microphone amplification circuit using LMV1012 and OPA375.
The schematic is below.
I want to connect this circuit to a Bluetooth module(BM20, Microchip…
Part Number: OPA375 Hi,
I was looking at the OPA375 and saw that this device has a max offset voltage of +-500uV under he test conditions. I then took a look at the figures lower in the datasheet and had a hard time understanding figure 7-4 (offset voltage…
Hello Ron Michallick ,
Thank you for the additional information. I'll keep a footprint for C5/C6 in any case.
I have three topics where I kindly ask you to weigh in.
Regarding op amp choice , you are suggesting OPA375 instead of OPA334. Do you suggest…
Part Number: TLV9361 Other Parts Discussed in Thread: LMV1012 , , OPA375 , LP2982 Tool/software: Hi, Ti.
I constructed an electret microphone amplification circuit using LMV1012 and TLV9361.
When I designed a circuit with a single 3.7V battery and an OPA375…
Part Number: OPA375 Other Parts Discussed in Thread: TINA-TI , OPA735
Tool/software: TINA-TI or Spice Models
The above circuit is a V-I circiut, the input voltage is 0-5V and the output current is 4-20mA. The amplifier is OPA735 and the NPN bipolar transistor…
Dear Jerry-san,
Thank you reply.
> I do not see any issues with the schematic as implemented, but you may not see the desired result on your output depending on your input.
I thank you for your confirmation work.
Also, I will try to manufacture a…
Hi,
If you are looking for the lowest noise setup, I would not use a TL431 as it is a noisy device relative to other voltage references. The main source of the reference voltage should come from either a REF3425 or a REF5025. These 2 devices have our…
Hi Steven,
Thanks for posting your question on E2E!
Firstly, the TLV9051IDBVR can currently be sampled on TI.com for evaluation, and will be fully released in September.
However, my recommendation to replace the MCP6021 would be our OPA375IDCKR device…
