Part Number: OPA388 Other Parts Discussed in Thread: OPA392 , TINA-TI , INA240 Hi,
We are using the design below. We observe that the output of the OPA388IDBV oscillates. We think that is due to the capacitive load on its output (400nF)
Could you please…
Part Number: OPA388 Other Parts Discussed in Thread: UCC27211 ,
Hi all,
I have custom design BLDC driver board with OPA388 amplifier and UCC27211 gate driver IC. I attached the 3 phase current measurement screens. I couldn't measure the third phase as…
Part Number: OPA388 Hi,
In the article below it describes the way to achieve zero offset for an amp.

Chen,
I believe you are not operating the circuit properly. When IB+ is measured, you must open S1 but S2 must be closed. Similarly, when you measure IB-, you must open S2 but S1 must remained closed - see below.
I have simulated the circuit and get…
Part Number: OPA388-Q1 Other Parts Discussed in Thread: OPA320-Q1 , OPA376-Q1 dear Sirs
Currently I plan to use OPA388-Q1 in CC/CI MODE application whether there will be any problem ?
Part Number: OPA388 Hi team, My customer wants to try the high temperature and high humidity test(THB). Could you tell me the test condition? I think that it should be carried out under the test conditions of the data sheet with JEDEC. Sincerely. Kengo.

Hi, my customer is looking for the least noisy and drifty OPAMs . Typical gain at low frequency…
Part Number: OPA388 Hi Team,
Our customer is using OPA388 but a ringing appears everytime he change the state from low to middle or high to middle voltage from a DAC of a microcontroller. Please see the waveform below for reference. He mesured the output…
