Hello-
We need help picking an op amp and drive circuit for driving a highly capaciitive load. Refer tothe attached circuit diagram.
The original plan was to use the LM8272 to replace the AMP01, but the absolute max voltage spec on LM8272 is (V+, V-) 27 Volts. That is a problem in this application.
Can you suggest a higher voltage part (+/- 18V) at least, i.e. surface mount, dual op amp, cap driver…………. similar to LM8272.
Thanks and Best Regards,
Tim Starr on behalf of Al Kumar
Hi Timothy,
Indeed we have an excellent dual operational-amplifier that meets, or exceeds, the LM8272 performance; the TLE2142CD (SOIC), or TLE2142CP (TSSOP). It can handle supplies up to +/-22V and drive hefty capacitive loads.
