Le blog de l'entreprise Mingjiada Supply ADI LT6604, LT6600 And LT1997 Series Low Noise Differential Amplifiers

With the continued development of industrial automation, medical imaging, 5G communications, test and measurement, and new energy systems, high-precision differential signal conditioning has become a critical component of analog front-end design. To meet the market’s growing demand for high-performance differential amplifiers, Shenzhen Mingjiada Electronics Co., Ltd. has long been a supplier of the [ADI] LT6604, LT6600, and LT1997 series of differential amplifiers. This product series covers applications such as low-noise ADC drivers, differential signal conditioning, and precision high-voltage differential acquisition, providing engineers with a diverse range of options from low-noise ADC drivers to high-voltage precision current sensing.

Focus on High-Speed Signal Chains: LT6600 / LT6604 Series

The LT6600 series is a line of low-noise differential amplifiers introduced by ADI that integrates a low-pass filter, significantly simplifying high-speed ADC front-end design. This series offers cutoff frequency options of 2.5 MHz, 5 MHz, and 10 MHz, making it suitable for driving 16- to 18-bit high-precision ADCs. Its differential input/differential output architecture, adjustable gain, and adjustable output common-mode voltage help improve system dynamic range and reduce distortion.

The LT6604 series can be considered a dual-channel version of the LT6600; it also integrates a differential amplifier and a low-pass filter and is available in 2.5 MHz, 5 MHz, and 10 MHz versions. With excellent channel-to-channel matching and a compact package, it is ideal for multi-channel data acquisition, I/Q signal chains, medical ultrasound front ends, communications receivers, and industrial measurement equipment. For systems that need to process multiple differential signals simultaneously, the LT6604 effectively saves board space and simplifies design.

For High-Voltage Precision Measurement: The LT1997 Series

Unlike the LT6600/LT6604, which focus on ADC driving, the LT1997 series is positioned as a high-voltage, high-precision differential amplifier. This series includes gain options such as the LT1997-1, LT1997-2, and LT1997-3. Featuring a wide common-mode voltage range, high common-mode rejection ratio, and low offset voltage, it is suitable for applications such as high-side current sensing, motor control, power supply monitoring, battery management systems, and industrial automation.

In motor drives and power supply systems, the LT1997 series can accurately extract minute differential signals in high common-mode voltage environments, helping systems achieve more reliable current-loop control and fault protection. Its design, which integrates precision resistors, also reduces the number of external components and improves overall accuracy and stability.
