Hello:
I am designing a new pcb and planning on using the ADA4870 as a buffer G=1 output driver.
Vcc=12V ; Vee=-12V
Signal shall be at max 20 Vpp and BW 3Mhz
The design requires that by an external signal the output shutdown so using the SD pin or the ON pin shall solve that.
One operation condition shall be that the IC must shutdown the output while it has a 20Vpp signal at the input.
Will it work? or may the signal leak into the output due to the high amplitude ?
PD
The circuit will replace and old pcb that uses AD8016 that unfortunately has this problem.
If you use the BIAS pin to shutdown and the input is over 8Vpp it does not work.
Unfortunately this is not mentioned in the datasheets.
