MSP430FR6007: ADC Channel

Hello Vivek,

Thanks for your post.

In our application required 16 Channel Sigma delta ADC. I have read in datasheet USS block has High-performance high-speed 12-bit sigma-delta ADC (SDHS) with output data rates up to 8 Msps. 

How many channel support sigma-delta ADC? 

The USS module supports one input channel. The PGA has two input channels, but one of the channels is a dummy input, which has the same input impedance of the real input. The dummy input is designed to meet the impedance match requirement between transmit mode and receive mode of one channel. You can learn more about this configuration in the USS and SAPH sections in the MSP430FR58xx, MSP430FR59xx, and MSP430FR6xx Family User's Guide.

It has 16 ADC Channel, Is this channel is different that USS block or the same one.

I think you're referring to the ADC12_B module which has up to 16 inputs but is different and separate from the USS module.

I hope this clarifies your questions. If you truly need a Sigma-Delta ADC with 16 inputs, please check out our Precision ADCs (<=10MSPS).

Hi James, 

Thanks for your reply. 

We will require MCU which have 12 or 16 Sigma Delta channel. Can you please suggest series for that ?

Do you have any MCU which will be used for three phase metering application?
