  • BUF634A: Paralleling devices

    Part Number: BUF634A Other Parts Discussed in Thread: OPA2677 , , OPA2670 , BUF634 Tool/software: Dear Support Team, We consider paralleling a few (say, four) BUF634As to increase the output current. Is it advisable? We cannot find any notes in this topic…

  • BUF634A: BUF634AIDR delayed start up/output time

    Part Number: BUF634A Other Parts Discussed in Thread: BUF634 Tool/software: Greetings, I am testing BUF634AIDR as a replacement/upgrade for the obsolete OPA633KPG4. I currently have a prototype SMT-to-TH adapter board built: BUF634AIDR, 0.1uF caps on…

  • BUF634A: Radiation hardened version for space application?

    Part Number: BUF634A Hello! I am looking for a rad-hard high speed buffer that essentially at least matches the specs of the BUF634A. My main concern is that it should have a slew rate of at least 20V/us and be able to drive at least 200 mA through a…

  • BUF634A: BUF634A current noise in Tina is inconsistent with data sheet

    Resolved
    Part Number: BUF634A Other Parts Discussed in Thread: TINA-TI I'm running a simple simulation of the BUF634A in Tina, looking at noise. To measure the current noise, I put a 1 Mohm resistor on the input, and measure the output noise. Simulating the…

  • BUF634A: Max voltage in single supply configuration

    TI Thinks Resolved
    Part Number: BUF634A I am unclear on what the max voltage I can use for the BUF634AIDR in single supply mode since in the recommend conditions it states max of ±18V, but in descriptions and absolute max it states it can go to 36V. Would I be able…

  • BUF634A: Output headroom?

    Resolved
    Part Number: BUF634A Other Parts Discussed in Thread: OPA1655 Please elaborate on the Output Headroom spec in the datasheet. Is this saying the Vpp of the output will be around 2V less potential on each the positive and negative supply - so with a +/-12V…

  • BUF634A: Output offset voltage questions

    Part Number: BUF634A Other Parts Discussed in Thread: BUF602 , BUF634 Hi, I made some observations while testing a BUF634A buffer (in real life). The offset voltage between input and output signal seems to be greater when it is sinking than when it is…
