Hi all, Any replacement recommended for DRV101T with different packaging more common nowadays? Thanks.
View ArticleForum Post: RE: DRV101 Different Packaging Replacement
Hi Hong, The DRV101T is in a TO-220 package, an alternative would be the DRV101FKTWT which is in a surface mount TO-263 package. I hope that helps!

Hi, I'm using LM96551 / LM96530 / AFE5803 to build a prototype. 8 channels of the LM96551 were parallel connected to excite a 2000pF ultrasound transducer. A picture below shows a received signal. A...

Hello, I've got a question regarding the load that the LM96551 sees in your system. You mentioned 2,000pF ultrasound transducer while we anticipate from 200-300pF for the equivalent capacitive load!...

Hi， Hooman. Thanks for your reply. I'm sure we use a single element ultrasound transducer with a 2000pF capacitive load. That is why we use eight channels of the LM96551 parallel to increase the drive...

Phx, The AFE5803 has an AC coupled input and variable HPF in the LNA. The ADC also has a digital HPF. The analog HPF is recommended but let me know if you need to reduce the cut-off frequency. Thanks,...
