300 MHz voltage-feedback amplifier in SOT-23-5
The Maxim MAX4212EUK+T is a single-supply, voltage-feedback operational amplifier delivering 300 MHz -3dB bandwidth and a 600V/µs slew rate from a SOT-23-5 package. It is designed for high-speed signal conditioning where board space is tight — think video distribution, ADC drivers, or pulse amplification in test equipment.
The 300 MHz -3dB bandwidth and 600V/µs slew rate together define the large-signal capability. For a 2 Vpp output step, 600 V/µs slews the edge in about 3.3 ns, which keeps pulse fidelity clean up into the tens of megahertz. If your application is driving a high-speed ADC input or buffering a video signal, these numbers tell you the part will track the input without slew-induced distortion — provided the feedback network is laid out for it. The 5.5 mA supply current per channel is a reasonable trade for this speed grade; lower-power siblings exist if the bandwidth requirement is relaxed.
The rail-to-rail output stage swings within millivolts of each rail, which matters when you are trying to get the last bit of dynamic range from a single 3.3 V supply.
Temperature range and deployment environment
The input offset voltage is specified at 4 mV max, and input bias current runs 5.4 µA — both stable across temperature but worth budgeting in precision DC-coupled paths. For a high-speed amplifier in this temperature grade, the AC performance (bandwidth, slew rate) typically derates gracefully; the datasheet's typical performance curves are the reference.
