概述

说明

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.
