The MAX2130 broadband, low-distortion, low-noise,

two-output amplifier performs preamp, loop-out, and

buffer functions in TV tuner applications. The device

integrates functions typically achieved with discrete

components into the space-saving 8-pin µMAX-EP

package. The MAX2130 provides a gain of +15dB with

a noise figure less than 3.2dB over the 44MHz to

878MHz frequency range. The MAX2130 features an

externally adjustable bias control, set with a single

resistor, that allows the user to meet minimum linearity

requirements while reducing current consumption. The

device operates from a +5V single supply and only

requires 93mA of supply current when nominally

biased.
