Additional Details

The TA7368F typically operates within a supply voltage range of 1.8V to 5.5V. It features a low noise amplifier (LNA) to boost weak FM signals, a mixer to downconvert the RF signal to an intermediate frequency (IF), and a local oscillator to provide the necessary frequency for the mixing process. The image rejection ratio is typically around 60dB, ensuring good selectivity. The current consumption is typically in the range of a few milliamperes, making it energy-efficient. Package options include SOP (Small Outline Package) for surface mount assembly.
