Amplifiers from Analog Devices deliver both high performance and high value. These amplifier ICs combine circuit design, manufacturing process innovation, and applications expertise to create products that simplify signal conditioning design.

Analog Devices offer a variety of online and downloadable tools to help engineers quickly select the right amplifier product. Please see the resource section below for popular amplifiers, related information, and tools.

ADC Drivers

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.

Differential Amplifiers

Differential amplifiers from Analog Devices are highly integrated and optimized for differential signaling applications. These devices have inherent common-mode rejection properties, provide low harmonic distortion, and have excellent output gain and phase matching. Whether you’re driving or receiving signals over long cable lengths, driving a balanced ADC input, or looking for complementary outputs, ADI has the differential amplifiers to meet your needs.

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.

Isolation Amplifiers

Isolation Amplifiers provide power supply designers with a higher performing, single chip alternative to isolation techniques based on optocouplers and shunt regulators. Analog Devices ADuM3190 and ADuM4190 isolated error amplifiers have a 400 kHz bandwidth, with 0.5% typical initial accuracy at 25°C and 1% total accuracy over the extended temperature range of –40˚C to +125˚C. This provides manufacturers of ac-to-dc and dc-to-dc power supplies with a significant upgrade in speed and operating temperature range, as well as a 5× improvement in transient response.

Operational Amplifiers (Op Amps)

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.

Use our resources in reference designs (Circuits from the Lab®), design tools, tutorials, and application notes to help select the right amplifier and simplify your design.

Variable Gain Amplifiers (VGA)

Variable gain amplifiers (VGAs) are used in a variety of remote sensing and communications equipment. Variable gain amplifiers deliver unmatched performance for signal chains that require high dynamic range. Applications ranging from ultrasound, radar, LIDAR, wireless communications, and speech analysis have utilized VGAs to deliver industry leading performance.

Video Amplifiers and Analog Video Functions

Analog Devices has the right solution for designers requiring an amplifier used as a buffer at a gain of 1 or 2. Our easy to use video amplifiers and complementary products for analog video functions are specifically optimized for a particular gain, which helps minimize your design time.
