SAR utilizes a built-in Digital to Analog Converter ... Pretty much all high bandwidth, high precision converters work this way. You can have ~14 bits effective at >100 MHz this way.

Precision digital-to-analog converters (DAC) are an integral part of the signal chain and are the primary facilitator of highly accurate signals. The precision DAC is typically used to fine-tune gain ...

What is a precision analog microcontroller? A precision analog microcontroller combines high-performance analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) with a single ...
