Part Number: OPA846 Other Parts Discussed in Thread: THS4551 Hi
The datasheet of the device claism 1.75GHz GBP and 400 MHz BW with G = +10 (front page of the datasheet)
The common rule for maximum achivable BW yields: BW = GBP/G = 175 MHz for G = 10
Part Number: OPA846 Other Parts Discussed in Thread: TINA-TI , , OPA657 Tool/software: TINA-TI or Spice Models Hi all,
I am now using opa846 and opa657 as TIA .But the output signal is abnormal in shape and amplitude when i simulate the amps by TINA.The…
Part Number: OPA846 Background:
I am using an OPA846 in a transimpedance amplifier with ~100 kOhm of gain. There is a resistor equal to the gain resistor connected to the non-inverting input to cancel the DC offset caused by the input bias current. This…
the OPA862 is a HF-OPAmp and in HF-TIA-applications higher input bias currents are usually tolerated, because often only the AC content of photodetector signal is used. Offset voltages caused by the voltage drop of input bias current across the…
Other Parts Discussed in Thread: OPA846 Hi Team,
A customer is looking for a part with an open-loop gain greater than 20dB or as high as it comes at 20MHz. with low noise of 1nV/RT-HZ or up to 2nV/RT-HZ.
Can you please help?
Other Parts Discussed in Thread: OPA846 , TINA-TI , OPA354 Hi guys
I'm trying to make a high gain amplifier which consists in two stages of 40dB each (x100). I'm using the OPA846 which should fulfill the gain requirements for at least 1 MHz bandwidth. The…
Other Parts Discussed in Thread: OPA380 , OPA846 Dear sir,
I am a student and doing on an optical sensor project.
Figure 1. whole circuit.
I choose OPA380 as the TIA, transimpedance gain is set to 1K, choose OPA846 as the post amp with gain of 470, when…
Other Parts Discussed in Thread: OPA846 , TINA-TI Hi All, We'd like to ask the measurement of phase margin and gain margin on OPA846. <Question> Please refer to attached file.This is the result of phase and gain simulation using OPA846. OPA846 is …
