Part Number: ADC3221

Hi all

Would you mind if we asked ADC3221 ?

What is the power consumption (per Ch) value of this device at 25MSPS in mW/Ch?

ADC322x Dual-Channel, 12-Bit, 25-MSPS to 125-MSPS, Analog-to-Digital Converters datasheet (Rev. E)

says that it is 116mW/Ch at 125Msps.

I would like to know the value at 25Msps.

Best Regards

Hi Amy,

I'm sorry.

I mistyped the value.

I would like to know the power consumption (per Ch) value of this device at 20MSPS.

We apologize for the inconvenience.

Hi Ryusuke,

In the datasheet on pg. 40, Figure 6-125 shows a graph of "Power vs Sampling Speed (One-Wire Mode)". At 20 MSPS this graph shows ~115 mW total power consumption for dual channel, or ~57.5 mW per channel.
