Maxim Integrated MAX479CSD Precision Operational Amplifier

The MAX479CSD from Maxim Integrated is a high-performance, precision operational amplifier designed for a wide range of applications that require accuracy and stability over time and temperature. This operational amplifier is a perfect choice for applications such as test equipment, instrumentation, and control systems where precision is key.

The MAX479CSD features a low offset voltage of typically 50µV and a low drift of 0.3µV/°C, ensuring reliable performance even under changing temperature conditions. The device also boasts a high open-loop gain, which contributes to its excellent linearity and ensures low total harmonic distortion (THD), making it ideal for audio applications and signal conditioning in high-fidelity systems.

In terms of power efficiency, the MAX479CSD excels with its low supply current of typically 1.1mA per amplifier, which is particularly beneficial for battery-powered and portable devices. Despite its low power consumption, this operational amplifier does not compromise on dynamic performance, providing a gain-bandwidth product of 1.8MHz and a slew rate of 2.8V/µs.

The MAX479CSD operates from a single supply voltage of +4.5V to +36V or dual supplies of ±2.25V to ±18V, giving designers flexibility in various supply configurations. Its common-mode rejection ratio (CMRR) of typically 120dB and power supply rejection ratio (PSRR) of typically 130dB ensure stable operation against fluctuations in supply voltage and common-mode signals.

This device is available in a compact 14-pin SOIC package, which is suitable for space-constrained applications. The MAX479CSD is also characterized for operation over the extended industrial temperature range of -40°C to +85°C, providing reliable performance in harsh environments.

Overall, the Maxim Integrated MAX479CSD operational amplifier is a robust, precise, and efficient solution for designers looking to enhance the accuracy and integrity of their analog signals in a variety of electronic systems.
