Part Number: DRV2700
Hello team,
We are evaluating the DRV2700 for a piezoelectric micropump application.
Our target waveform is:
Piezo load: 6 nF typical, up to 25 nF
100 Hz typical, 200 Hz maximum
Bipolar square-wave drive
Approximately…
Part Number: DRV2700 Hi,
I am using the DRV2700 to drive a piezo. We had some issues with the inputs earlier and added protection. We have been up and running with no issues for quite a while. We have recently had some issues with the outputs not being…
Part Number: DRV2700 Hello,
I am bringing up a new PCB design based on the DRV2700 in boost mode driving a piezo printhead. Before connecting the piezo, I am validating the boost converter by enabling a single channel.
I have one board that exhibited…
Part Number: DRV2700 I am evaluating the TIDU994A TI reference design that uses the AB5027B-3-LW100-R piezoelectric transducer and noticed an apparent discrepancy with the transducer manufacturer's specifications.
According to the piezo datasheet, the…
Part Number: DRV2700 Hi team,
Could you help review DRV2700 schematic is okay or NOT? Due to cuatomer's PCB can not work. I remove R3/R4 and injetion +-2V sin to pin17/pin16. but Out +- no waveform.
I compare with EVM. found some discovering phenomena…
Part Number: DRV2700 I am running it in flyback mode. It is working, but I have some question.
I'm using a variable output circuit with an opamp, as described in the datasheet.If I suddenly change the output value, the feedback voltage drops and the…
Part Number: DRV2700 To whom it may concern,
I'm evalauting use of DRV2700 for driving high voltage piezo load and need help to understand following:
what is maximum frequnecy for sinusoidal drive signal?
what is max load current boost can suppport…
Part Number: DRV2700 Hi Team,
We want to design a 0 to 200V sine wave output for our project, so we chose the DRV2700 in flyback mode.
We designed and simulated the circuit in TINA software. We are getting 200V, but the output is not a pure sine wave…
