Comparators

A comparator is used to compare a measurable quantity with a reference or standard such as two voltages or currents. It outputs a digital signal showing the results. Analog Devices offers an extensive portfolio of high speed and low power comparators and this allows us to provide our customers with more complete signal chain solutions. Our comparator offerings range from the fastest Si-based comparator on the market today to very low power CMOS comparators that consume only microamperes of power. Find the right comparators for your application with our selection tool and design tool.

Difference Amplifiers

Differential Amplifiers

Analog Devices Single and Fully differential ADC drivers offer precision DC specs and are designed to better reject high frequency PSRR and CMRR through their differential input and output architectures. Analog Devices ADC drivers configured for both precision and high speed differential amps come with a VOCM pin, providing a critical but convenient solution when interfacing with analog-to-digital converters (ADCs). Key performance in any ADC driver is achieved by quickly settling out the considerable sampling glitch energy delivered to the amplifier output(s) by the ADC input’s sampling circuit. Whether you need to drive a single or dual differential input ADC or send and receive signals over long cable lengths, Analog Devices has developed a broad portfolio of high speed differential amplifiers that provides the high performance needed to meet any requirement. The differential input and output also offer system improvement by reducing the total harmonic distortion received by the ADC.

Instrumentation Amplifiers

Analog Devices instrumentation amplifiers (in-amps) are precision gain blocks that have a differential input and an output that may be differential or single-ended with respect to a reference terminal. These devices amplify the difference between two input signal voltages while rejecting any signals that are common to both inputs. The in-amps are widely used in many industrial, measurement, data acquisition, and medical applications where dc precision and gain accuracy must be maintained within a noisy environment, and where large common-mode signals (usually at the ac power line frequency) are present.

Operational Amplifiers

The operational amplifier (op amp) is an important part of any analog signal chain, often working as a crucial part of the interface between sensors and our world-leading ADCs. Common analog op amp functions include gain, buffering, filtering, and level-shifting. Analog Devices’ portfolio provides the broadest choice of op amps in the industry, delivering unmatched quality, robustness, and performance to enable optimized solutions in automotive, industrial, consumer, and healthcare markets. Explore op amps by parameters and find expert system-level advice on design problems with our reference designs (Circuits from the Lab®), design tools, selection guides, filter design, calculators, and LTSpice®/SPICE models for operational amplifiers.
