The TDA4321XS includes a 7 stage capacitive coupled-limiter amplifier with coincidence demodulator and AF output. The AF output signal can be continuously attenuated to decrease the noise.
In case of multipath interferences, the TDA4321XS includes an identification circuitry with analog output.
There is a field strength output (with min. 76 dB dynamic range, typ. ±1 dB nonlinearity and typ. ±3 dB temperature drift), an IF-Counter output and an adjustable muting (with full muting 80dB). An STS output with adjustable threshold and stop window is available.
