Part Number: OPA615 Other Parts Discussed in Thread: BUF602 , , TINA-TI , OPA860 Following the datasheet figure 48 bipolar peak detector circuit using the OPA615 in TINA the negative Vout- doesn't work as expected. The positive Vout+ will track the Vpositive…
Other Parts Discussed in Thread: BUF602 , OPA615 , OPA860 , OPA356 , TINA-TI Hello,
I need a high speed peak detector which can detect surge voltage however rising time of my voltage is approximately 0.7 ns.I read the TI forum note with OPA615 and BUF602…
Hi Priya,
Since the propagation delay is only 4.5ns, yes, you should be able to sample at 50MHz (20ns). What is the amplitude and period of your pulse and what is your desired hold amplitude and period?

Hi Yatao,
a fast integrator can be built by using the diamond transistor in the OPA860 or OPA615. You might want to have a look at this thread:

Other Parts Discussed in Thread: OPA860 , LM13700 Hello everyone,
I have done a voltage controlled const current source using OPA860 but OPA860 operating voltage is limited to 6.5 volts. I want max voltage for my application.
I saw Lm13700 IC with…
Other Parts Discussed in Thread: OPA615 , OPA860 We need to drive a single-turn coil for a calibration-loop antenna, with a diameter of approximately 50cm, and at frequencies of the order of 100Hz to 10kHz. We need to have a very high output impedance…
Hello James,
A couple of quesrions:
1. The OPA860 is a transconductance amplifier (VtoI) converter. For your application an opamp configured as a transimpedance amplifier would be more suitable.
2. The BW of a pulsed application is better determined…
The solution you propose would work, but from a matching pespective, you should use 2x OPA861 with a linearisation resistor in between. The buffer of the OPA860 is a closed loop buffer that is much faster than the diamond buffer of the OTA. Specs like…
