High-speed voltage-feedback amplifier for signal-chain duty
The Maxim Integrated MAX4414EUA+T is a single voltage-feedback op-amp designed for applications requiring wide bandwidth and fast slew rate without excessive supply current. Its 400 MHz -3 dB bandwidth and 200 V/µs slew rate suit it for video distribution, ADC front-end buffering, and high-speed signal conditioning in test equipment or communications gear.
The 200 V/µs slew rate means the output can swing several volts in tens of nanoseconds, which is the difference between a clean pulse and a slew-limited ramp when driving a flash ADC or a 75 Ω video line. Pair it with the 400 MHz -3 dB bandwidth and you have an amplifier that can handle fast transient signals without significant distortion up to several megahertz. The 1.3 µA input bias current and 500 µV input offset voltage are typical for this speed class, so plan for a DC servo or digital calibration if the application demands sub-millivolt precision.
Package and layout notes
The 75 mA output current per channel is adequate for driving moderate loads, but the small thermal mass means the junction temperature climbs quickly if you sustain high current into a low-impedance load—derate accordingly. A solid ground plane under the package helps with thermal and electrical performance.
Lifecycle and compliance
No LTB or EOL window has been announced, so it is safe to qualify into new designs.
