THS3001: THS3001 burns up

Hi,

I built a circuit based on a typical circuit, but the chip would burn as soon as it was powered on, which made me confused.

This is the schematic of THS3001.

    Hi Gang,

    unless you made a wiring mistake, burning damage can be the result of unwanted oscillation due to instability. The best measure to achieve stability is the use of a ground plane as recommended in the THS3001's evaluation module:

    I guess your layout doesn't look like this?
