Small Analog-to-Digital Converters (ADCs)

Using Small ADCs to Supplement MCUs with Integrated ADCs

Having an ADC on your microcontroller (MCU) is easy, convenient and inexpensive. However, there is some inherent peril: converter performance can be compromised and relying on the converter to deliver the necessary performance without a backup plan can cause costly redesigns. 

Thankfully, our portfolio of ultra-small converters is a great backup plan. These devices are small enough to include in the board layout process without a significant increase in the cost or size of the PCB. This results in a win-win situation because if the existing ADC on the processor is good enough, there is virtually no impact. If an external converter is needed, you simply need to populate the spaces that are already present.
