A "low power" analog-to-digital converter (ADC) consumes less power than most of other similar products on the market for a given application. There isn't a power specification that immediately qualifies an ADC as a low-power product because various applications and architectures have different thresholds for what is considered low power. This page highlights Maxim's lowest power ADCs for many applications.
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 links below refer to Maxim's lowest power ADCs and are 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.
Here is a sampling of Maxim's best low-power ADCs:
High-performance ADC includes a high-dynamic range sample-and-hold and a high-speed serial interface. These ADCs accept a full-scale input from 0V to the power supply or to the reference voltage and consume only 5.2mW at 3Msps and 3.7mW at 2Msps.
Industry-leading 1.5MHz, full linear bandwidth, high speed, low-power, 12 bit serial output successive approximation register (SAR) ADC.
The MAX11200/MAX11210 are ultra-low-power (< 300µA active current), high-resolution, serial output ADCs. These devices provide the highest resolution per unit power in the industry, and are optimized for applications that require very high dynamic range with low power, such as sensors on a 4mA to 20mA industrial control loop and handheld instruments.
This 16-bit, 1.6Msps, single-channel, fully differential SAR ADC has internal reference buffers, provides excellent static and dynamic performance with best-in-class power consumption while providing an SPI output.
