MAX4476ATT+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4476ATT+T is a single-channel, wideband operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from +2.7V to +5.5V and draws 2.2mA of quiescent current per amplifier. The device features a gain-bandwidth product of 10MHz with unity-gain stability and a slew rate of 3V/µs. Key electrical characteristics include an input offset voltage of ±70µV at 25°C, an input bias current of 1pA, and an input voltage-noise density of 4.5nV/√Hz at 1kHz. It provides rail-to-rail output swings and is housed in a space-saving TDFN-6 package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Ultra-low noise performance with low input voltage-noise density and low input current-noise density.
• Low distortion characteristics suitable for high-fidelity signal processing applications.
• Single-supply operation capability down to 2.7V with true rail-to-rail output swings.
• Input common-mode voltage range includes ground potential.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix ATT+T corresponds to the TDFN-6 package configuration as indicated in the manufacturer's documentation. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the supply voltage range aligns with your system design constraints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel amplifier with unity-gain stability is required. It is appropriate for designs needing low noise and low distortion within a 10MHz bandwidth. Consider alternative models like the MAX4488 if higher gain-bandwidth products or shutdown functionality are necessary for the application.
