Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

In the design of precision signal chains, operational amplifiers, instrumentation amplifiers and isolation amplifiers are like the "nerve endings" of the system, directly determining the accuracy and reliability of data acquisition. As a seasoned distributor of electronic components, Shenzhen Mingjiada Electronics Co., Ltd. relies on a global inventory network of over 2 million models and a dual warehousing system in Shenzhen and Hong Kong to provide a full range of ADI amplifiers in stock for the fields of industrial automation, medical equipment, and new energy vehicles. With a three-in-one service of "original factory authenticity + express delivery + in-depth technical empowerment", Resolve the dual challenges of supply chain and technology for engineers.

The ADI amplifiers supplied by Mingjiada Core

1. Operational amplifier

The operational amplifier (operational amplifier) is an important component of the analog signal chain and is usually an essential part of the interface between the sensor and the ADC. Common functions of analog operational amplifiers include gain, buffering, filtering and level conversion. ADI's product range offers a wide selection of operational amplifiers, featuring outstanding quality, reliability and performance, providing optimized solutions for the automotive, industrial, consumer electronics and healthcare markets. You can search and browse operational amplifiers by parameters, and find system-level expert advice on related design issues through reference designs (Circuits from the Lab®), design tools, selection guides, filter designs, calculators, and LTSpice®/SPICE models of operational amplifiers.

2. Instrument amplifier

The instrumentation amplifiers of ADI are precision gain modules. The input is differential type, and the output can be either differential type or single-ended type relative to the reference end. These devices can amplify the difference between the voltages of the two input signals while suppressing any signals shared by 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 involve large common-mode signals (typically AC power line frequencies).

3. Isolated amplifier

Isolated amplifiers can provide power designers with a more performant 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% within the extended temperature range from -40 °C to +125 °C. This enables AC-DC and DC-DC power supply manufacturers to significantly increase the speed and operating temperature range, while improving the transient response by five times.
