Device Structure

Composed of two independent operational amplifiers in a single integrated circuit. Uses CMOS technology for low power operation. Surface mount 8-SOIC package for compact circuit designs.

Performance Characteristics

Offers rail-to-rail output for maximizing dynamic range in low-voltage systems. Ultra-low power supply current suitable for battery-sensitive applications. Low input bias current and low input offset voltage provide stable, accurate signal amplification. Optimized for low frequency and steady-state applications due to its moderate gain bandwidth and low slew rate.

Application Environments

Best for battery-powered devices, handheld instruments, portable medical equipment, sensor interfaces, and signal conditioning in low voltage and low power systems. Suitable for use in industrial, commercial, and consumer electronics where power efficiency is a priority.

Selection Guidelines

Choose MAX4242ESA when your design needs two amplifiers in one package, low power consumption, and rail-to-rail output. Ensure your supply voltage and system temperature fall within the rated limits. Consider obsolete status when planning for long-term production—prefer alternatives for new designs. Confirm compliance needs, as this part is not RoHS-compliant.

Usage Considerations

Account for its maximum supply and output current ratings to avoid device damage. Obsolete status means future supply may be limited—purchase excess stock if needed for ongoing projects. Not recommended for high-frequency or high-speed applications due to limited gain bandwidth and slew rate. Not RoHS-compliant—avoid in environmentally restricted designs.
