High-Performance, Stand-Alone ADCs for a Variety of Embedded Systems Applications SAR CONVERTERS – LOW-POWER 100 KSPS AND 250 KSPS, 10 AND 12-BIT ADCs. The MCP3001 and MCP3201 are 10- and 12-bit SAR ADCs that offer standby currents of less than 1 µA, and 3 SAR ADC Design (5) Targeting the Test and Measurement application, this section includes many topics relevant to designing with SAR ADC devices. 17:19.

A major disadvantage of SAR ADC is its design complexity and cost of production. Applications of SAR ADC As this is a most commonly used ADC, it's used for many applications like uses in biomedical devices that can be implanted in the patient, these types of ADCs are used because it consumes very less power.
