LM4050-N-Q1: Supply to multiple ADC128S102QML and DAC121S101

Danilo A.

Part Number: LM4050-N-Q1

Hi Team,

Figure 14 of the datasheet of LM4050QML and Figure 43 of DAC121S101WGRQV show that it can be used as power supply and reference to ADC128S102QML and DAC121S101WGRQV. Our customer would like to know how many ADCs or DACs can be placed on one LM4050-5.0QML. There are ten DAC121S101WGRQV and three ADC128S102WGRQV in their application.

Regards,

Danilo

Hello,

To more properly respond to your inquiry could you please answer the following:

1. What is the total load current the customer is expecting at the LM4050QML output?

2. Is each DAC and ADC running in parallel or are they being sequenced?

Regards,

Oscar Ambriz

Hi Oscar,

There seems to be a bug in our E2E Forum site because I can't find this post a few minutes after posting so I created another one in the link below. You will noticed that there is a 30min time difference between the two post. Anyway, thank you very much for your help!
