Hi Benham,
The OPA837 is the best match for your system requirements as many of our transimpedance amplifiers have much higher power consumption than the OPA837/OPA838. The OPA837 is also unity gain stable. The OPA837 however, does have a larger voltage…
Part Number: OPA817 Other Parts Discussed in Thread: THS4541 , OPA837 Tool/software: Hello TI experts, my design includes two OPA817 with a gain of 1.1 and 3.3. Are there some recommandation from TI for the "best" feedback resistor values in case of…
Part Number: ADC3644 Other Parts Discussed in Thread: OPA837 , , REF3318 Hi team,
In the EVM of ADC3644, 1.6V of VREF is divided and supplied by REF3318 and OPA837. Is this because there was no 1.6V reference? If I use the ADC3644 with an external reference…
Hello Chia,
I realize I did not include an explanation for my earlier statement. The OPA817 and OPA818 do not have high impedance outputs when in power down (PD). The OPA837 does have high impedance outputs when in PD, and is used for muxing in TIDA-01565…
Part Number: OPA838 Other Parts Discussed in Thread: OPA855
As all the datasheet has mentioned, we need to remove GND and PWR plane underneath the negative inverting pin and the output pin of the operational amplifier (It is important to avoid ground…
Hi Gerald,
the "OPA837.LIB" file which you can find here
OPA837 TINA-TI Spice Model (Rev. B)
can easily be imported into LTSpice:

Hello Conor,
The first figure shows the front-end receiving circuit using the OPA607 for high input impedance input and the following it with the OPA837 as a variable gain mux / PGA and bandpass filter as shown in reference design TIDA-01565. The second…
Part Number: LMP7704-SP Other Parts Discussed in Thread: LMP7704 , , OPA837 Hello,
I am looking for the TINA model file that is presented in SNOAA75A (Space-Grade, 100-krad, 125-kHz Photodiode TIA Circuit),
A snippit from the pdf is shown below.
Thank…
