DAC7552: Data output control issues

Part Number: DAC7552
Other Parts Discussed in Thread: DAC60502, DAC63202

Hi Dear，

We have a customer looking at DAC7552, which is used for laser galvanometer control. They would like to know if it is possible to control data output in some way after receiving data in the DAC input register?

The customer has referred to AD5687/9 and there is an LDAC pin, as shown in the following figure.

However, DAC7552 does not have an LDAC pin. May I ask if there are other ways for DAC7552 to control data output

    Hi Anna,

    This device has a clear input that clears both output channels to zero-scale. But there is no LDAC input. 

    We do have devices with LDAC pins if the customer is interested in other devices. They could consider the DAC63202 which has a GPI pin that can be configured as an LDAC, or DAC60502 which has a software LDAC trigger. 

    Best,
