MAX4335EXT+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4335EXT+T is a single-channel, high-output-current operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply voltage ranging from 2.7V to 5.5V and delivers up to 50mA of output current. The device features rail-to-rail inputs and outputs, a 5MHz gain-bandwidth product, and a quiescent supply current of approximately 1.8mA at 5.5V. It is housed in a 6-pin SC70 package and specified for an operating temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output stages designed for low-voltage, single-supply operation
• High output drive capability delivering 50mA into loads as low as 32Ω
• Integrated thermal overload protection that activates above +140°C junction temperature
• Smart short-circuit protection limiting output current to 110mA during fault conditions

Instrumentation, Op Amps, Buffer Amps Applications

• Mono/stereo headphone drivers in portable applications
• Portable and battery-powered instruments
• Wireless PA control circuits
• Hands-free car phones
• Transformer and line drivers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix EXT+T against official manufacturer documentation to confirm the exact package type (SC70-6) and RoHS compliance status. Ensure the component matches the intended single-channel configuration and temperature grade (-40°C to +85°C). Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel amplifier with high current drive is required in a minimal footprint. It is suitable for designs needing rail-to-rail signal swing on both input and output sides. Consider the 5MHz bandwidth and 1.8mA quiescent current for power-sensitive portable applications. Verify that the load requirements do not exceed the 50mA continuous drive capability or trigger the internal short-circuit protection thresholds.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX4335–MAX4338 family of high-output-current op amps. While the MAX4335 is a single-channel unit, the family includes dual-channel variants (MAX4336/MAX4337) and quad-channel options (MAX4338). All members share similar electrical characteristics but differ in channel count and package availability. The MAX4335 specifically targets mono audio applications requiring compact packaging.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements within the same family include the MAX4336EXT+T, which shares identical electrical specifications and pinout but may differ in top marking. Other packages such as SOT23-8 or μMAX are available for different channel counts but require schematic and layout adjustments.
