need help using max544

Dear all

I'm new here, I got confused when using Arduino to control a DAC chip max544. The DAC has a pin called SCLK, what it should be connected,a pwm pin? How to control Arduino to generate a 14-bit serial ? Does anyone have a example about control a DAC like that? Many thanks.

I'm not familiar with the MAX744. And neither is Maxim.

Are you sure you have the right part number there?

It sounds like you have an SPI device there.

This it?

SPI - Arduino Reference

That's quite embarrassing, it is MAX544.

Ah, that's better,

So, you connect DIN to MOSI (Uno 11), and SCLK to SCK (Uno 13). CS normally goes to SS (Uno 10), but any IO pin can be used. LDAC, if it's like the MCP chip I use, can be just tied to ground to permanently enable the latch, or controlled by an IO pin to do controlled latching.
