Hi May,
Op Amps have issues when driving capacitive loads. It introduced another poles within the feedback loop. Generally, op amp will have a single pole roll off at -20dB/decade. If a second pole is generated within the feedback loop, it rolls off…

Hi,
I would like to inquire about the input protection behavior of the OPA4197 and possible alternatives to the OPA4323.…
Ian,
Stimulating the output of U1 op amp with short duration current pulses shows instability of the circuit - see below.
The main reason for instability are the multiple feedback loops causing too much time delay between input and output (too…
Part Number: THP210 Other Parts Discussed in Thread: OPA392 , INA592 , OPA2392 , OPA388 Tool/software: Dear All,
I am designing a fully differential first order low pass filter as part of an ADC drive signal chain. I want to use the THP210 and have…
Part Number: LMP2012 Other Parts Discussed in Thread: OPA387 , OPA388 Hello,
I have witnessed that the LMP2012 takes a long time to settle after the input signal switches from one value to another. This settling time and error depend on the amplitude…
Part Number: OPA2211A Other Parts Discussed in Thread: OPA725 , OPA388 Hi All,
I have a question about the graph of OPA2211A. Please tell me the measurement circuit of Fig.5 below.
Best Regards, Ishiwata
Other Parts Discussed in Thread: ADS131M08 , OPA388 , OPA2189 , THP210 , OPA189 , OPA392 , REF6225 , ADS131M08EVM I am interfacing my TI ADC ADS131M08 with a sensor that gives out 0.5V to 4.5V signal.
I am looking to find a high precision (ultra low…
Part Number: OPA2388 Other Parts Discussed in Thread: OPA388 I am using one of the dual opamps of this chip. I am using single supply 5V and Ground. Power supply is duly filtered using capacitors and is clean.
Pin 8 -----> 5V
Pin 4 ------> GND …
Jonathan,
Chopper amplifiers are an excellent choice for low offset, and low offset drift. However, the chopping calibration process generates current transients on the inputs of the amplifier that translate into input offset when large feedback and…
