Part Number: OPA188
Dear team, I simulated this circuit diagram. The simulation result is wrong, I don't know where the problem lies. I attach the simulation file. Thank you! 5238.OPA188_TEST1.TSC
Part Number: OPA188 Other Parts Discussed in Thread: OPA192 , Dear amp support,
A customer uses the OPA188 for an oscillator. It doesn’t work very well and it is confirmed by the simulation. They replace it by OPA192.
Is OPA188 a chopper stabilized…
Part Number: OPA188 I made a circuit like the one shown in the figure and actually measured it, but the offset voltage was too small to be confirmed with an oscilloscope. I would like to know if there is a measurement method that can be used with a measuring…
Hi Vegard A , You can refer to the article mentioned in OPA188: how to calculate the signal bandwidth that can pass in a TIA circuit - Amplifiers forum - Amplifiers - TI E2E support forums to accurately calculate and simulate the TIA bandwidth. Article for…
Part Number: OPA188 Other Parts Discussed in Thread: OPA2188 , Hi team,
I see OPA188 has +- 0.7 differential limit. Is it due to the diode clamp? I didn't see OPA2188 has this limit in datasheet.
Thanks.
Part Number: OPA188 Other Parts Discussed in Thread: LM10 , OPA454 Hey there
I need to run a circuit simulation involving OPA188 but I cant find a compatible SPICE model. I'm using EasyEDA which uses standard SPICE2 and SPICE 3 models but the only…
Part Number: OPA188 Other Parts Discussed in Thread: TINA-TI , INA592 Hi team,
Do you have document of AN to show caculation of amps gain error, our customer use 4 external resistor and OPA188 to design differential amps, they need to know how to caculate…
Part Number: OPA187 Other Parts Discussed in Thread: OPA188 , Tool/software: Hi support team.
Could you please provide some information about the method and measurement environment for measuring the input bias current of the OPA188 introduced in the application…
Part Number: OPA188 Other Parts Discussed in Thread: OPA187 , We have been using the OPA188 in a number of new development and pre-production projects. We have obtained the OPA188 from three different sources and they all have the same major problem. They…
