MAX4450EXK+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4450EXK+T is a single-supply, rail-to-rail voltage-feedback operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from +4.5V to +11V single supplies or ±2.25V to ±5.5V dual supplies. The device features a small-signal bandwidth of 210MHz and a slew rate of 485V/µs with a quiescent current of 6.5mA per amplifier. It offers a common-mode input range extending beyond the negative supply rail and outputs that swing within 55mV of either rail. Packaged in an ultra-small SC-70-5 format, it supports operation from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with single-supply or dual-supply configurations as required by the system design. Confirm RoHS compliance status through manufacturer datasheets before integration into production environments.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring wide bandwidth and high slew rates in compact designs. Consider the SC-70-5 package for space-constrained layouts. Evaluate power supply requirements against the specified operating voltage range. Assess thermal dissipation capabilities relative to the maximum power dissipation limits under expected load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4450/MAX4451 family of ultra-small, low-cost, high-speed op amps. The MAX4450 is the single-channel version packaged in SC-70-5 or SOT23-5, while the MAX4451 provides dual channels in SOT23-8 or SO packages. Both share identical electrical characteristics optimized for video and RF signal processing.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional equivalents within the same family include the MAX4451EUK+T (dual channel, SOT23-5) and MAX4451EKA+T (dual channel, SOT23-8). Verify pinout compatibility when substituting between single and dual channel variants.
