BUF18830: Customer need clear BUF18830EVM schematic

Paul Yeh

Part Number: BUF18830

Hi Team,

My customer would like to draw BUF18830 schematic and they plan to reference BUF18830 EVM board circuit. But it is not clear enough to reference.

So could you share the link how to download clear schematic for customer?

Thanks

Hi Paul,

The user guide evm schematic is the only one available. The EVM schematic has feature not needed in regular application, like dual type socket, external/internal control..

A better starting point for the schematic is data sheet PCB recommendations.

Let me know the components not clear in BUF18830 EVM User Guide schematic

Regards,

Costin

Costin,

Customer asked one question about connection. Due to the Panel is no VCOM feedback pin, so they would like to know how to connect IC's pin3 & pin10 connection?

Thanks

Hi Paul,

VCOM1&2 are non inverting Op-amps, the external resistors set the gain.

In most applications the gain is set to one( follower) . If so:

-R1 and R4 are open

-R2 and R5 are 0ohm
