Part Number: OPA388 Other Parts Discussed in Thread: TINA-TI I'm using the OPA388 in a current-measurement design. I use the '388 to amplify (Gain = 10,000) the voltage across a shunt resistor, with the expectation that 200uA into the shunt generates…
Part Number: OPA388-Q1 Other Parts Discussed in Thread: OPA388 , OPA2388 Hi,
I would like to add overvoltage protection to the input side of OPA388. Do you have any suggestion ?
Part Number: OPA388 Other Parts Discussed in Thread: OPA387
Dear team,
At datasheet, We can see difference condition of Vout range as load register value 10K or 2K ohm.
1. Is there any specific meaning of Vout range per load value in test condition?
Please…
Part Number: OPA388 Hi,
I am using OPA388 in simulation and I am quite dispointed to notice that in follower configuration I obtain as low as 10kHz cut-off frequency.
Could you please tell me if this is excepted or if there might be a problem with my…
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…
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 Hi,
In the article below it describes the way to achieve zero offset for an amp.
