Looking for SMT high speed OP AMP
with 2500V/uS slew rate, above 160MHZ bandwidth and 0V-+18V power supply.
OPA633KPG4 is ok, but it has through-hole package.
I want to use this op amp to drive BUF634 for getting 250mA output current.
Please let me know.
Have a nice weekend.
For the SMT op amp, take a look at LM7171/LM7372 (single/dual, stable at Av >= +2 or -1) or LM6172 (dual, unity-gain stable). Both of these are VFB op amps that can meet your speed, supply voltage, and SMT requirements. Note that the slew rate for these devices is proportional to the input level, and higher slew rate can be achieved in lower closed-loop gain configurations.
For high output current buffer, you may also consider LMH6321, which has 300 mA output current, adjustable current limit pin (resistor set), and is available in 8-pin PSOP (SOIC with Thermal Pad ) or 7-pin TO-263 SMT packages.
So many thanks for your answers.
Do you have TINA simulation models for them?
There are PSPICE models available for these device on their respective product folders as well as on the SpiceRack page.
See this applications report for Importing a SPICE netlist into TINA-TI.
My sincere thanks to you.
