Hello Abhinaba,
Yes, that is correct. For high speed applications, especially for an amplifier such as the OPA846, it is highly recommended to use a PCB to prototype/test your design. Breadboarding your design with very high speed amplifiers cause instability…
Part Number: OPA846 I need to edit this curve, any idea what software created this and perhaps that source file?

Part Number: OPA846 Dear TI team,
I have one TIA ckt to be reviewed. I cant share it here. Please share your email ID so that i can DM the ckt & requireemnt details.
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…
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…
The GBP definition, and what you need for TIA design, is the single pole projection to 0dB. Get that by going to the Aol=40dB point and multiplying that frequency by 100X, 1.59GHz here,
This recent article tries to explain this confusion, and also some…
