MAX2180A

AM/FM Car Antenna Low-Noise Ampliﬁer

General Description

Features

● +6V to +24V Supply Voltage Range

The MAX2180A 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 fre-

quency range, while the FM signal path covers 65MHz to

162.5MHz.

● Integrated AGC Function Eliminates External Pin

Diodes

● High Dynamic Range

● Low-Noise, Sub 3dB Noise Figure

● Low External BOM

● Integrated Thermal Protection

● Small Package (4mm x 4mm TQFN)

● Integrated Pass Device and Linear Regulator

● Integrated Power Detector

The device integrates a voltage regulator and pass tran-

sistor, allowing operation using battery voltages in the

+6V to +24V range. On-chip thermal protection automati-

cally limits junction temperatures during extreme thermal

conditions.

● Integrated Antenna Sense

The device is available in a small, 4mm x 4mm, TQFN

package and operates over the extended industrial tem-

perature range (-40ºC to +85ºC).

Applications

● Automotive Active Antenna
