Mingjiada Supply Maxim MAX44244, MAX44245 And MAX44248 Low Power Operational Amplifier

As demand for ‘high precision, low power consumption and wide voltage range’ continues to rise in industrial control, portable medical devices, sensor interfaces and data acquisition systems, precision operational amplifiers have once again become key components in signal chain design. Shenzhen Mingjiada Electronics Co., Ltd. — a long-standing supplier of Maxim’s high-precision, low-power electronic components, including the MAX44244/MAX44245/MAX44248 series of 36V precision low-power operational amplifiers. This series comprises single-channel, dual-channel and quad-channel versions, catering to applications such as industrial control, precision instrumentation, medical equipment and battery-powered devices, whilst providing reliable component support and supply chain assurance for the industrial, medical, instrumentation and battery-powered equipment sectors.

36V Precision Low-Power Operational Amplifier Series
The MAX44244, MAX44245 and MAX44248 form part of Maxim’s range of precision, low-power operational amplifiers, available in single-channel, dual-channel and quad-channel versions respectively. This series features a wide 36V supply voltage range, microampere-level quiescent current, low input offset voltage and rail-to-rail output, making it suitable for applications with stringent requirements for accuracy, power consumption and supply voltage range.

Key Feature Advantages
The MAX44244/MAX44245/MAX44248 series offers the following features:
Wide supply voltage range: Supports supply voltages from 2.7V to 36V, compatible with common system voltages such as 3V, 5V, 12V and 24V.
Low quiescent current: Typical quiescent current of approximately 130µA per channel, helping to extend the battery life of battery-powered devices.
High precision and low offset: Input offset voltage as low as 10 µV, with offset drift of approximately 0.05 µV/°C, reducing the need for system calibration.
Low-noise design: Suitable for precision small-signal amplification, enhancing the signal-to-noise ratio of sensor front-ends.
Rail-to-rail output: Fully utilises the ADC’s input dynamic range to improve sampling accuracy.
Unit-gain stability: Facilitates the construction of buffer, amplifier, filter and bridge amplifier circuits.
Industrial-grade temperature range: Suitable for applications in harsh environments such as -40°C to +125°C.
