1GHz, Low-Power, SOT23,

Current-Feedback Amplifiers with Shutdown

_______________________________________________________________________________________

Note 1: The MAX422_EUT is 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by design.

Note 2: Absolute Maximum Power Dissipation must be observed.

Note 3: Does not include impedance of external feedback resistor network.

Note 4: AC specifications shown are with optimal values of RF and RG. These values vary for product and package type, and are

tabulated in the

Applications Information section of this data sheet.

Note 5: The AC specifications shown are not measured in a production test environment. The minimum AC specifications given are

based on the combination of worst-case design simulations along with a sample characterization of units. These minimum

specifications are for design guidance only and are not intended to guarantee AC performance (see

AC Testing/

Performance). For 100% testing of these parameters, contact the factory.

Note 6: Input Test Signal: 3.58MHz sine wave of amplitude 40IRE superimposed on a linear ramp (0IRE to 100IRE). IRE is a unit of

video signal amplitude developed by the International Radio Engineers. 140IRE = 1V.

Note 7: Assumes printed circuit board layout similar to that of Maxim’s evaluation kit.

AC ELECTRICAL CHARACTERISTICS (continued)

(VCC = +5V, VEE = -5V, SHDN = 5V, VCM = 0V, AV = +1V/V for MAX4223/MAX4225/MAX4226, AV = +2V/V for MAX4224/MAX4227/

MAX4228, RL = 100Ω, TA = +25°C, unless otherwise noted.) (Note 4)
