Part Number: DRV2700EVM Tool/software: How do I determine the maximum drive frequency of TI Piezo HV driver evaluation boards such as the DRV2700EVM or DRV2667EVM (or other) for a given piezo capacitance load? We need to specifically explore generating…
Part Number: DRV2700EVM-HV500 Other Parts Discussed in Thread: DRV2700 Tool/software: Hi,
I would like to increase the output voltage of DRV2700EVM-HV500 to 1000V, can you please suggest me a way to do that? I look forward to hear from you soon.
Thank…

Hi, T.I.
I am testing with DRV2700EVM-HV500.
I test by adjusting the PWM Input Frequency, but the expected waveform does not appear.
Waveforms can be distinguished up to 5000Hz, but beyond that, waveforms…
Part Number: DRV2700 Tool/software: Hello TI Support,
I am using DRV2700 EVM for my piezo driver needs, but I see that voltage at the output significantly drop when i put switches to 500 V setting. I also observe voltage drops at other voltage settings…
Part Number: DRV2700EVM Other Parts Discussed in Thread: DRV2700 Tool/software: 在测试DRV2700EVM时,使用官方压电控制台,空载电压可以达到100V,负载电压可以达到80V,但是使用外部信号源输入音频信号时,最高电压只有10V左右(外部信号源通过耳机线传输电脑产生的音频信号),我们至少需要70V,能不能帮忙看看是哪里出了问题?
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: MSP430F5510 Other Parts Discussed in Thread: UNIFLASH , DRV2700EVM Hi, T.I.
I am trying to update the DRV2700EVM's firmware to the latest version, 1.7, using UniFlash.
But I keep getting the “No USB FET was found” error.
I…
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…
