Datasheet
19-5322; Rev 0; 6/10
The MAX2180 is a highly integrated AM/FM variable-gain
low-noise amplifier ideal for use in automotive active
antenna applications. The device features separate
AM and FM signal paths, each providing 30dB of gain
range, controlled by individual on-chip power detectors.
The AM signal path covers a 148kHz to 30MHz input
frequency range, while the FM signal path covers 65MHz
to 162.5MHz.
The device integrates a voltage regulator and pass tran-
sistor, allowing operation using battery voltages in the
+8V to +24V range. On-chip thermal protection automati-
cally limits junction temperatures during extreme thermal
conditions.
The device is available in a small, 4mm x 4mm, TQFN
package and operates over the extended industrial tem-
perature range (-40NC to +85NC).
