DRV2700EVM: pin occupancy for control a signal 0 - 48 V

Steve Horky

Part Number: DRV2700EVM

Hello,

i need the correct pin occupancy.
My external analog signal has an amplitude of 4 V without an offset (-2 V to 2 V). At the output i need 0 V to 48 V. So i need an offset of 24 V and a gain of factor 12.

How i have to set the jumper for my application?

I experiment a lot but when i enable the DC-Offset at Pin TP8 (-IN) the output break down.

Hi Steve,

Do you want the output to switch from -24V to +24V, giving a differential output across the load a 48V swing? Or do you want to use the device in single ended mode and drive one output from 0V to 48V while the other output of your load is grounded.
