MAX4187ESD+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4187ESD+ is a quad current-feedback amplifier from the MAX4180 family, housed in a 16-pin QSOP package. It operates on single +5V or dual ±2.25V to ±5.5V supplies with 1mA quiescent current per amplifier. Optimized for unity gain (+1V/V), it delivers a 270MHz small-signal bandwidth and 450V/µs slew rate. The device features excellent video specifications including 0.08% differential gain error and 0.03° phase error, alongside low distortion (-73dBc SFDR).

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ESD+' against the manufacturer's official documentation to confirm pinout compatibility and exact electrical tolerances. Ensure the 16-pin QSOP footprint matches your PCB design constraints. Cross-reference the datasheet revision date to validate that all AC and DC parameters align with your system requirements before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MAX4187ESD+ when a quad configuration is required for unity-gain buffering or driving. It is distinct from the MAX4186, which is compensated for gains of +2V/V or greater. This part is suitable for designs needing high bandwidth and low power within a compact surface-mount package, particularly where video signal integrity is critical.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the MAX4180 series of high-speed, low-power current-feedback amplifiers. The series includes single, dual, and quad variants with different gain compensation profiles. The MAX4187 specifically addresses the need for four independent channels optimized for voltage follower configurations, offering a balance of speed and power efficiency in a space-saving QSOP enclosure.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX4186 serves as a functional alternative if the application requires a closed-loop gain of +2V/V or higher rather than unity gain. Both share similar power and packaging characteristics but differ in internal frequency compensation.

Instrumentation, Op Amps, Buffer Amps FAQ

What is the minimum operating supply voltage for the MAX4187ESD+?

The device can operate from a single +5V supply or dual supplies ranging from ±2.25V to ±5.5V.

How does the shutdown feature affect the output state?

When the SHDN input is pulled low, the supply current reduces to approximately 135µA, and the outputs enter a high-impedance state.

Is this amplifier compensated for gains lower than +1V/V?

No, the MAX4187 is specifically compensated for applications with a closed-loop gain of +1 (0dB) or greater.
