What is the THS4567IRUNR?
It delivers a 500V/µs slew rate and a 220 MHz gain-bandwidth product, with a -3dB bandwidth of 43 MHz, making it suitable for applications like radar receiver chains, communications infrastructure, and test equipment that need to preserve signal integrity at high frequencies.
A 500V/µs slew rate means this amplifier can track a full-scale 2 Vpp signal at frequencies well above 10 MHz without the slew-induced distortion that limits slower amplifiers. For a 5 V supply swing, the full-power bandwidth is roughly 16 MHz before the output starts slewing. If you are driving a 12-bit or 14-bit ADC sampling at 50 MSPS or higher, this part keeps the harmonic distortion low enough to not degrade the converter's SFDR.
The THS4567IRUNR comes in a 10-WQFN package measuring 2 mm × 2 mm. That is a small thermal pad QFN — no leads to inspect visually, so X-ray or a continuity check on the board is the way to confirm the joint. The part is surface mount only, no socket option. On the rework bench, pre-bake at 125°C for 8 hours if the moisture barrier bag has been open longer than the floor life; the small pad wets quickly with a hot-air nozzle at 300°C.
The 200 µV input offset voltage and 20 pA input bias current hold across the temperature range, so the DC accuracy does not drift off when the equipment heats up.
