Maxim Integrated MAX473ESA Precision, Low-Power, Quad, Single-Supply Op-Amp

The MAX473ESA from Maxim Integrated is a high-precision, low-power operational amplifier designed to offer a blend of features that make it ideal for battery-powered applications and systems requiring multiple op-amps. This quad operational amplifier is built to operate from a single supply, ranging from +4.5V to +36V, or dual supplies of ±2.25V to ±18V, providing design flexibility for a variety of circuits.

One of the key features of the MAX473ESA is its low-power consumption, drawing a quiescent current of only 210µA per amplifier, which is particularly beneficial for portable devices where power efficiency is crucial. Despite its low-power nature, this op-amp does not compromise on performance, offering a high slew rate of 0.5V/µs and a gain-bandwidth product of 1MHz, which makes it suitable for low-frequency applications such as sensor interfacing, audio processing, and other analog signal conditioning tasks.

The device's precision characteristics include an input offset voltage of just 500µV and an input offset current of 20nA, ensuring accurate signal amplification with minimal error. Additionally, the MAX473ESA features a common-mode rejection ratio (CMRR) of 120dB and a power supply rejection ratio (PSRR) of 120dB, which contribute to its stability and noise immunity, even in the presence of supply voltage variations or common-mode disturbances.

Designed with versatility in mind, the MAX473ESA comes in a compact 16-pin narrow SO package, making it a space-saving solution for dense PCB layouts. Its wide operating temperature range of -40°C to +85°C allows for reliable operation in diverse environmental conditions. Furthermore, the MAX473ESA is equipped with short-circuit protection, enhancing the robustness of the device in harsh electrical environments.

Whether you are developing precision instrumentation, low-power filters, or any application requiring multiple high-performance op-amps, the MAX473ESA by Maxim Integrated is an excellent choice that combines efficiency, precision, and reliability in a single package.
