Part Number: DRV2700EVM-HV500 Other Parts Discussed in Thread: DRV2700 Hi, I'm Jeon Hyeon Min.
I'm using DRV2700EVM-HV500 for driving piezoelectric actuator.
What I want is 0~158V AC sine wave output for 0~200Hz using DRV2700EVM-HV500.
So I found…
Part Number: DRV2700EVM-HV500 Hello, I'm Jeon Hyeon Min
Although I read DRV2700EVM-HV500 User's guide so many time, I don't understand how to use DRV2700EVM-HV500.
Here's my questions.
1. I'm using piezoelectric actuator which has 0.8…
Part Number: DRV2700EVM-HV500 Hello,
New and not know much about of Piezos, but I have DRV2700EVM-HV500 and got few piezocermic trimorph bending actuator. So can I drive bender with this evaluation board? Bender guide says "It is suggested to use a series…
Hi Bruno,
If the piezo is operating differently between the two, then the two output signals must be different. An oscilloscope screen shot would really help debug this issue. Without it, there isn't much I can do.
Regarding the noise, you are operating…
Other Parts Discussed in Thread: DRV2700 , DRV2700EVM Hello everybody, I downloaded TINA TI version 9.3.200.277 SF-TI However, I did not find the model for the DRV2700EVM device on your premises, is the model available so that it can be included in the software…
Part Number: DRV2700EVM Hi team,
Currently i am using DRV2700EVM to drive a piezo actuator AE0203D16DF (350nF). Then I use DAC64204 as my Input supply to the DRV2700EVM. I use the DAC to supply constant voltage 0-4V to the TP7 and TP8 I connect to ground…
Part Number: DRV2700EVM Other Parts Discussed in Thread: DRV2700 , Hi, I am trying to develop a piezo driver board using the DRV2700. For this, a development board of the DRV2700EVM is order. I need to drive the pump at the frequency of 21.5kHz - 24.5 kHz…
Hi
I have used a standard DRV2700EVM with default current limit and inductor . According to my calculations (Section 8.2.1.2.8 of datasheet) the current through actuator should be 5.8mA and inductor peek at 195mA . While the current limit on EVM is 2…
Part Number: DRV2700EVM Hello TI support teams,
Operating Condition: 5V external power I am currently using the DC-coupled input, but I found some unexpected spikes in the output signal, which is not periodic. Is it normal? If it is not, where does it…
Part Number: DRV2700EVM-HV500 Hello, My customer has a DRV2700EVM-HV500 but does not currently have a piezo element to connect. It seems that it will take a long time to acquire a piezo element. They want to evaluate the DRV2700EVM-HV500 output by connecting…
