Arnaud Mercier / Open seismic electrical design - History

Verification of all pins of the LT7101

According to the datasheet and DC2895A demoboard

Place new molex connector on board

Molex 2 positions connector for 12V and A-B connections

Added via to bottom ground plane

DRC, via to GND and 3D model

Finished connection and zone

The Vbb and Vin have returned to separate nets and zones. In this configuration the spike of volage when turning on the source at the surface will be handle by C1,C2 and C3.

Plane configuration

The Vin and Vbb are merged into a single net. Is the C1 to C3 usefull then? Must revise the decoupling strategy

Preliminary placement of components on the power supply board

3 planes are : Vbb or Vin, GND (top and bottom) and Vout

symbol to footprint association for power supply

Datasheet and footprint added to every component. all component are stored in the digikey cart
