MAX4483ASD

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4483ASD+ is a quad, low-cost, general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2.5V to +5.5V supply and draws only 50μA of quiescent current per amplifier. The device features rail-to-rail output voltage swing, capable of driving a 5kΩ load while swinging within 80mV of the rails. It is unity-gain stable with capacitive loads up to 400pF. The MAX4483ASD+ is specified for operation across the -40°C to +125°C temperature range and is housed in a 14-pin SO package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ASD+' against the manufacturer's official ordering guide to confirm the exact package type (SOIC-14) and lead-free/RoHS compliance status. Ensure the intended application environment falls within the guaranteed -40°C to +125°C operating temperature range. Confirm that the single-supply voltage requirements align with the +2.5V to +5.5V specification limits before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier topology is required alongside strict power conservation constraints. The MAX4483ASD+ is suitable for designs needing rail-to-rail output performance without the complexity of dual-supply configurations. Consider its 50μA quiescent current draw for portable devices. Note that unlike the MAX4481, this specific model lacks a shutdown pin, so power management must be handled externally if needed.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4483ASD+ belongs to the MAX4480–MAX4483 family of low-cost, general-purpose op amps. While the MAX4480 is a single channel, the MAX4483 provides four channels in a 14-pin TSSOP or SO package. This family shares core characteristics like 50μA quiescent current and rail-to-rail outputs but differs in channel count and physical packaging options.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the MAX4483AUD+ (TSSOP-14). For different channel counts, consider the MAX4480 (single) or MAX4482 (dual). Verify pin compatibility and electrical specifications against the original design requirements before substituting.
