Device Structure

Integrates two amplifier circuits in one chip, housed in a compact 10-pin surface-mount package, optimized for tight PCB layouts. Push-pull output structure delivers rail-to-rail voltage swing, maximizing dynamic range in low supply voltage applications.

Performance Characteristics

Low input bias current and offset voltage for precision signal amplification. High gain bandwidth enables fast signal response and accurate analog processing. Low supply current supports battery-operated and low-power devices. Capable of driving moderate loads with up to 68 mA output current per channel. Wide supply voltage range suits many control and mixed-signal applications.

Application Environments

Used in portable instruments, industrial control, signal conditioning, sensor interfacing, audio processing, and battery-powered devices. Suitable for environments requiring surface-mount, compact, low-power, and precision analog signal amplification from -40°C to +85°C.

Selection Guidelines

Choose this amplifier for dual-channel applications needing rail-to-rail output, low offset, and low input bias current. Verify supply voltage compatibility from 2.4 V to 5.5 V. Check RoHS compliance requirements, as this version is non-compliant. Consider gain bandwidth for high-speed applications up to 22 MHz. Ensure the form factor matches your PCB and assembly process.

Usage Considerations

Obsolete status means limited future support and supply; ensure adequate inventory or consider alternatives for new designs. Non-RoHS compliance may restrict use in some products or regions. Handle per MSL-1 requirements. Verify operating temperature range and supply voltages for reliable operation. Double check packaging type for assembly compatibility.

Potential Equivalent/Replacement Models

MAX4249EUB+ is listed as a direct substitute. For other alternatives, check for similar dual-channel, rail-to-rail, low-power op amps from Maxim Integrated, Analog Devices, Texas Instruments, ON Semiconductor, or Microchip. Because the product is obsolete and substitutions depend on specific design requirements (such as package type, offset voltage, bandwidth), it is advised to contact the Ariat-Tech sales team for a full list of suitable replacements or technical guidance.
