MAX4472EUD+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4472EUD+T is a quad micropower operational amplifier from the MAX4464/MAX4470 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +1.8V to +5.5V supply with a typical supply current of 750nA per amplifier. The device features rail-to-rail output capability, ground-sensing inputs, and unity-gain stability. Key electrical parameters include a gain-bandwidth product of 9kHz, an input offset voltage of ±0.5mV (max), and a large-signal voltage gain of up to 120dB. It is housed in a 14-pin TSSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm package type and RoHS compliance status. Ensure the component matches the required temperature range of -40°C to +85°C. Confirm that the quad configuration aligns with the design requirements before procurement. Check for any recent revision history updates that may affect performance specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low quiescent current is critical alongside rail-to-rail output swing. It is suitable for applications requiring unity-gain stability and ground-referenced inputs. Consider the 9kHz bandwidth limitation for high-speed signal processing tasks. Evaluate thermal dissipation capabilities within the TSSOP-14 package for dense PCB layouts.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4464/MAX4470/MAX4471/MAX4472/MAX4474 family of micropower op amps. The MAX4472 specifically provides four amplifiers in a single package, offering space savings compared to single or dual variants. It shares core characteristics like low voltage operation and low noise with its siblings but differs in channel count and compensation settings.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include MAX4470 (single) and MAX4471 (dual) if fewer channels are acceptable. For pin-compatible alternatives with different gain-bandwidth products, consider the MAX4464 or MAX4474 series, noting their stability requirements for gains greater than +5V/V.
