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 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…
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…
Hello Ali,
ali aykan said: 1. I plan to use INA293 (U1) as current sense amplifier. Is it suitable or should I use rail to rail zero drift amplifier like OPA188?
You could use either if VLOAD is under under the 15V but the OPA188 would need some more resistors…
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…
Part Number: OPA188 Other Parts Discussed in Thread: OPA187 , Does anybody know if the current noise specs for the OPA188 and OPA187 are correct? I am asking because the data sheets say 160 fA/√Hz for the OPA187 but only 7 fA/√Hz for the OPA188.…
Part Number: OPA188 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models OPA188 website's link is dead. I wanna use TINA model to simulate circuit.
Hi Kenta,
Vcm refers to the input voltage range. For V+ = 13 Vdc as simulated, the input range is from V- (GND or 0V) to (13V - 1.5V) = 11.5V for OPA188. We also indicate that the OPA188 is NOT Rail to Rail Input (RRI) op amp.
But OPA188 is classified…
