Precision Analog-to-Digital Converters (ADCs)

Analog Devices' broad selection of precision successive-approximation-register (SAR) and sigma-delta ADCs feature best-in-class combinations of high-resolution, fast data-rate, low-power, and small packages to support all high-accuracy measurement needs.

SAR ADCs are the workhorse products of the industry because they offer good resolution at high sampling rates. Analog Devices SAR ADCs offer some of the lowest power specifications in the industry while also offering accuracy specifications that are close to those provided by more expensive sigma-delta ADC's.

Analog Devices' precision sigma-delta ADCs offer world-class accuracy and resolution. These precision sigma-delta ADCs are set apart from the competition by their best-in-class power performance.

It is very difficult to select a "low-power" product from a parametric table because for most ADCs the power requirements scale with sampling rate. A product that uses very low power at low sampling rates can also consume high power when it is used at high sampling rates. The product below refers to Analog Devices' lowest power ADC and is recommended for use in portable, handheld products or battery powered designs. Because their power usage is generally scalable with sampling rate, the designer will generally select the lowest sampling rate to meet the design specification in order to conserve power.

Features and Benefits
