Part Number: OPA659 Other Parts Discussed in Thread: OPA892 , TINA-TI Tool/software: Hello,
I’m looking to simulate its performance using LTSpice. Unfortunately, I haven't been able to find a SPICE model for the OPA659 that's directly compatible with…
Part Number: OPA659 Hello,
I have built simple voltage follower using this opamp with single VCC 10V to gnd ( +Vs=10V , -Vs=0V)
If I short noninverting input to gnd directly or through 50R, the output goes to 1.14V. If I drive the noninverting input with…
Part Number: OPA659 Other Parts Discussed in Thread: TINA-TI Hello,
I have designed a peak detector circuit with OPA 659. My purpose was to measure the peak of the fast (about 300 kHz) signal. Therefore I connected the output of the opamp to microcontroller…
Part Number: OPA659 Other Parts Discussed in Thread: OPA656 , OPA855 , OPA858 , OPA847 , OPA657 HI
I just ordered a PCB board that involves OPA659IDBVT. But I cannot order OPA659IDBVT as it is out of stock now. Can you suggest me any updated IC with similar…
Part Number: OPA659 Other Parts Discussed in Thread: TINA-TI , OPA690 Hello,
I want to design high speed peak detector. Is it okay to use OPA659 opamp? (It works properly in Tina-TI simulation but I wanted to be sure)
I attached my simulation file below…
Hi Ignacio and Saket,
Thanks for your kind reply, I think in my case it is hard to calibrate the front-end digitally to get 0dB gain.
Anyway, it seems that OPA659, OPA814 and OPA817 can meet my requirements.
Thanks for your support.
BR,

Part Number: OPA659 Other Parts Discussed in Thread: OPA859 The OPA659 data sheet specifies the current noise as 1.8fA/rtHz at frequencies up to 10MHz. Does the current noise increase above 10MHz?
Part Number: OPA659 Other Parts Discussed in Thread: OPA653 , OPA656 Hello,
I have one question about Iq of OPA659.
According to datasheet, Iq spec is defined 32mA(typ).
I think that this is a little high comparing other OPAMP which have similar BW spec. …
Part Number: OPA659 Other Parts Discussed in Thread: OPA657 , LMH6629 , OPA857 Hi Team,
The customer is using OPA659. The customer uses the Figure 39. Wideband, Low-Noise, Transimpedance Amplifier (TIA) of the datasheet reference circuit for his
design. …

Hi,
I made a differential probe for my scope, but the output signal does not seem nothing I expected, TINA or any similar software simulates.
The input signal is 5V, 2MHz square wave, the output should be 5mV (1:1000). I tested the…
