Hi Said,
I checked with our PA Op amp Marketing Engineering team and they were able to provide me with some insight on the OPA237 and OPA188 longevity plans.
Despite the OPA237 being introduced 20 years ago, it is a widely applied op amp. The semiconductor…
Other Parts Discussed in Thread: OPA237 I am redesign a circuit with a unity gain buffer that I have had difficulty with due to the dual supply op amp requires the +/- rail voltage to come up equally (the dc-dc converter that powers this circuit the negative…

Thanks Thomas. Previously I was told to use TLV2262AM, OPA237, and LMC6001 instead.
Can you explain more in what terms TLE2021 is similar to LT1013 and better to use rather than the other ones? in terms of the location of the poles, frequency response…
Part Number: AMC1100 Other Parts Discussed in Thread: OPA237 , AMC1300 Hi,
AMC1100 component is used for sensing the RAW power supply AC supply 50Hz. The following ckt is used.
Here VDD1 is connected to 5V_Main_AC. 5V_Main_AC (5V DC) is generated from…
Other Parts Discussed in Thread: LT1013 , OPA237 , INA193 , LMC6001 I have the attached circuit as a Voltage Controlled (V_Control) Current Source (I-Load).
This circuit has an stability issue. When V_Control drops from 3.3 V to 0 V the circuit works fine…
Hi Javier,
1. According to TI Design( ), OPA237 is recommended and it uses both of positive & negative voltage. But customer wants to use only positive voltage.
Could you recommend other TI Design which uses only Positive voltage?
2. Is Demagnetization…
Part Number: OPA377-Q1 Other Parts Discussed in Thread: OPA377 , OPA237 I have a question regarding to OPA377 and OPA237. I use your OPA377 in differential amplifier. The schematic shown below.
The voltage I'm sensing is 32V. Voltage into the opto is 32V…
Hi All,
Interestingly OPA237 on my simulation using TINA is not working but OPA2234/LM321/OPA234 is working on TINA SPICE using this circuit.
I am now purchasing LM321 and OPA234 and OPA2234 and I will try again on bench.
I am just wondering why the…
Thank you very much for your concern.
After a brief inspection, the OPA237 is fairly similar to the OPA277. I think using the OPA237 should help you confirm the absence of the spikes.
I will make sure to test the DAC8831/2EVM when I have access to the…
