Part Number: OPA859 Other Parts Discussed in Thread: BUF802 ,
Tool/software:
I need to drive a 1GHz signal on a 1m 50ohm coax cable and am considering either OPA859 or BUf802. The OPA859 is in unity gain configuration and is somewhat preferable due to…
Part Number: OPA859 Hi,
On the OPA859 datasheet, there are some recommended values for the feedback resistor. For gains less than 3V/V, Rf should be 150 Ohm. For gains of 4V/V and greater, Rf should be 453 Ohm. Why these values? Can't I use other resistor…
Part Number: OPA859 Other Parts Discussed in Thread: LMH0307 , Hi, I have requirement of HD-SDI video buffer. The Serial Data rate of Video Chip is 1.485GHz and output swing is 900mVpp. Please suggest video buffer for this? Thank You
Part Number: OPA859 Other Parts Discussed in Thread: OPA659 , OPA2810 , OPA2822 , OPA858 , , TINA-TI I used the TI Filter Design Tool to get a 4-pole Butterworth design using two Sallen & Key stages. Corner frequency was design at 4 MHz, yet the simulation…
Part Number: OPA859 I want to know what is the maximum withstand voltage of PD terminal? For example, 5V or 3.3V will damage the PD pin? If it exceeds 1.8V, will it be considered as enable mode? What happens when the voltage exceeds 1.8V?
Part Number: OPA859 Other Parts Discussed in Thread: TINA-TI , , BUF802 Hello,
I am trying to include the OPA859 amplifier into a 3D EM Co-simulation with CST MWS for an integrated antenna and circuit simulation. I am unable to import the TINA-TI SPICE…

Anant thanks for the reply. I have already bought 10 pieces of OPA859 and several pieces of THS4501CD and ADS1115 module. The thing is that there is very little information on the Internet about connecting OPA859. I can’t understand much from the datasheet…
Part Number: OPA859 Hello,
I have two questions FB pin of OPA859.
1) At "6 Pin Configuration and Functions" of datasheet,
FB pin is I (input).
However, in Figure 50, the FB pin is connected to the output of the amplifier, so it looks like…
