Description
Max2130 Broadband, Two-output, Low-noise Amplifier For Tv Tuner Applications
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
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.
19-1806; Rev 1; 8/03
Pin Configuration appears at end of data sheet.
