ADI amplifier

ADC Drivers 

ADI's single differential and fully differential ADC drivers have precise DC specifications aimed at better suppressing high-frequency PSRR and CMRR through their differential input and output architectures. The ADC driver configured by ADI for precision and high-speed differential amplifiers has a VOCM pin, providing a critical and convenient solution for connecting to analog-to-digital converters (ADCs). Quickly eliminate a large amount of interference energy transmitted to the amplifier output through the sampling circuit of ADC input, thereby achieving critical performance in any ADC driver.

Differential amplifier

ADI's differential amplifiers are highly integrated and optimized for differential signal applications. This type of device itself has common mode rejection characteristics, can provide low harmonic distortion, and has excellent output gain and phase matching. Whether driving balanced ADC inputs or seeking complementary outputs, or sending and receiving signals through long cables, ADI has suitable differential amplifiers to meet application requirements.

Instrument amplifier

ADI's instrumentation amplifiers are precision gain modules, with differential inputs and outputs that can be differential or single ended relative to the reference terminal. These devices are capable of amplifying the difference between two input signal voltages while suppressing any signals shared between the two input terminals. Instrumentation amplifiers are widely used in many industrial, measurement, data acquisition, and medical applications, which require maintaining DC accuracy and gain accuracy in high noise environments, and there are large common mode signals (usually AC power line frequencies) present.

Isolation amplifier

Isolation amplifiers can provide power designers with a higher performance single-chip solution, which can replace isolation technologies based on optocouplers and shunt regulators. The ADI ADuM3190 and ADuM4190 isolated error amplifiers have a bandwidth of 400 kHz, a typical initial accuracy of 0.5% at 25 ° C, and a total accuracy of 1% in the extended temperature range of -40 ° C to+125 ° C. This can significantly increase the speed and operating temperature range of AC-DC and DC-DC power supply manufacturers, while improving transient response by 5 times.

Operational amplifier

Operational amplifier (op amp) is an important component of the analog signal chain, usually an important component of the interface between sensors and ADCs. Common functions of analog operational amplifiers include gain, buffering, filtering, and level conversion. ADI's product line offers a wide range of operational amplifiers with excellent quality, reliability, and performance, providing optimized solutions for the automotive, industrial, consumer electronics, and healthcare markets.

RF Amplifier 

ADI's RF amplifiers are designed using the company's leading amplifier and RF IC expertise, helping customers tackle their next design challenge with ease. Our RF amplifiers range from low noise amplifiers (LNAs) to high-power amplifiers, including GaN technology in the kHz to~100GHz range. Many products have been optimized for bandwidth, efficiency, power consumption, linearity, low noise, low phase noise, etc. to meet the most challenging performance requirements. These RF amplifiers are typically used in communication, instrumentation, aviation, and defense applications, but can also be used in various end markets.

RF front-end IC

ADI provides RF front-end ICs for phased array antenna solutions. These RF front-end ICs are directly placed on antenna components and can quickly switch between transmission and reception functions in radar applications. The power amplifier at the transmitting end is highly efficient during short pulse durations. The low-noise amplifier at the receiving end has a high linearity and low noise coefficient, so it will not distort the input return signal. The RF front-end IC also integrates a high-performance switch that can switch between the transmission and reception paths. Highly integrated planar phased array antennas require small-sized solutions, and ADI has integrated switch chips, low-noise amplifiers, and power amplifiers into small surface mount packages and decoupling capacitors, providing an ideal solution.

Broadband distributed amplifier

ADI's broadband distributed amplifiers based on GaAs MMIC cover the frequency range from DC to 65 GHz in various ultra wide bandwidths. Our design product catalog includes low-noise amplifier, power amplifier, and driver amplifier designs, which can meet your needs in applications such as electronic warfare, radar, electronic countermeasures, optical applications, and instrumentation. In order to meet various design requirements, some LNAs can also provide internal self bias, which only requires one signal drain voltage to operate.
