MAX4212EUK

The MAX4212EUK is one member of the MAX4212 series.These devices require only 5.5mA of quiescent supply current while achieving a 300MHz -3dB bandwidth and a 600V/s slew rate. Input-voltage noise is only 10nV/Hz and input-current noise is only 1.3pA/Hz for either the inverting or noninverting input. These parts are an excellent solution in low-power/low-voltage systems that require wide bandwidth, such as video, communications, and instrumentation. In addition, when disabled, their high-output impedance makes them ideal for multiplexing applications.

Features of the MAX4212EUK are:(1)single 3.3V/5.0V operation; (2)rail-to-rail outputs; (3)input common-mode range extends beyond VEE; (4)low differential gain/phase: 0.02%/0.02°; (5)high-output drive: ±100mA; (6)space-saving SOT23, MAX, or QSOP packages.Maxim recommends using microstrip and stripline techniques to obtain full bandwidth. To ensure that the PC board does not degrade the amplifier's performance, design it for a frequency greater than 1GHz. Pay careful attention to inputs and outputs to avoid large parasitic capacitance.

The absolute maximum ratings of the MAX4212EUK can be summarized as:(1)supply voltage:12V;(2)output short-circuit duration to VCC or VEE:continuous;(3)lead temperature:300;(4)operating temperature:-40 to 85;(5)storage temperature:-65 to 150.Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.These are stress ratings only, and functional operation of the device at these or at any other conditions beyond those indicated in the operational sections of the specifications is not implied.Exposure to absolute maximum rating conditions for extended periods may affect device reliability.The output voltage swing comes to within 50mV of each supply rail. Local feedback around the output stage assures low open-loop output impedance to reduce gain sensitivity to load variations. This feedback also produces demand-driven current bias to the output transistors for ±100mA drive capability, while constraining total supply current to less than 7mA. The input stage permits common-mode voltages beyond the negative supply and to within 2.25V of the positive supply rail.
