MAX4199EUA+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4199EUA+ is a micropower, single-supply, rail-to-rail precision differential amplifier manufactured by Analog Devices / Maxim Integrated. It operates from a single +2.7V to +7.5V supply or dual ±1.35V to ±3.75V supplies, consuming 42µA of supply current. The device features a factory-trimmed fixed gain of +10V/V and achieves a -3dB bandwidth of 45kHz. Key electrical characteristics include a maximum input offset voltage of 100µV, a common-mode rejection ratio of 110dB, and a shutdown mode that reduces current consumption to 6.5µA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Factory-trimmed internal resistors provide a precise fixed gain of +10V/V with low gain error.
• Rail-to-rail output stage allows the output to swing within 100mV of either supply rail when driving a 5kΩ load.
• Active-low shutdown control significantly reduces power consumption for battery-operated applications.
• Input common-mode voltage range extends beyond the negative supply rail without phase reversal.

Instrumentation, Op Amps, Buffer Amps Applications

• Instrumentation Amplifier Building Block
• Differential Voltage Amplifiers
• Data-Acquisition Systems
• Portable/Battery-Powered Equipment
• Current-Sense Amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'EUA+' corresponds to the 8-pin µMAX package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as indicated in official documentation. Check current availability through authorized distributors, as stock levels may vary. Ensure the application circuit matches the required +10V/V gain configuration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed gain of +10V/V is required for single-supply differential signal conditioning. It is suitable for applications needing low power consumption and high common-mode rejection. Consider the MAX4198EUA+ if a unity gain (+1V/V) configuration is needed instead. Verify that the 45kHz bandwidth meets the system's frequency response requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4198/MAX4199 series of micropower differential amplifiers. The series offers space-saving 8-pin packages including µMAX and SO. While the MAX4198 provides a gain of +1V/V, the MAX4199 is specifically designed for a gain of +10V/V. Both share similar power and performance characteristics within the Beyond-the-Rails family.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX4198EUA+ serves as a functional alternative within the same series but provides a fixed gain of +1V/V rather than +10V/V. Designers must adjust external circuitry or select a different gain setting if substituting this part. No other direct cross-references are confirmed in the provided documentation.
