The MAX480ESA from Maxim Integrated is a high-precision operational amplifier (op-amp) designed to operate with a single supply voltage as low as 1.0V and up to 6V, or with dual supplies of ±0.5V to ±3V. This versatility makes it an ideal choice for battery-powered applications and portable devices where energy efficiency is paramount.

Featuring a combination of low operating current and low input bias currents, the MAX480ESA is optimized for long-term performance in a variety of systems. Its quiescent current is a mere 45µA, which contributes to an extended battery life in portable applications. Additionally, the op-amp boasts a low input bias current of 1pA, which is particularly beneficial for high-impedance sensor applications and precision integrators.

The MAX480ESA offers excellent precision with an offset voltage of just 500µV and a gain-bandwidth product of 350kHz. These characteristics make it suitable for precision low-frequency applications, including sensor signal conditioning, portable medical devices, and battery-operated equipment. The device's common-mode rejection ratio (CMRR) of 120dB and power supply rejection ratio (PSRR) of 120dB ensure stable performance against changes in supply voltage and common-mode voltage, enhancing the accuracy of the signal processing.

Encased in a compact 8-pin SOIC package, the MAX480ESA is designed to be space-efficient, fitting easily into space-constrained designs. Its operational temperature range from -40°C to +85°C allows for reliable operation in a broad spectrum of environments.

Key features of the MAX480ESA include:

• Single-Supply Operation: 1.0V to 6V
