NS741 Catalog
NS741 is the low-power FM band transmitter with which the left and right audio signals can be modulated in FM with stereo multiplexing.
Features: Chip Description:
NS741 is the low-power FM band transmitter which enables the RDS (Radio Data System) data transmission. It is manufactured by full CMOS process. The built-in DSP realizes stable stereo signal generation and RDS data attachment. The direct modulation (the modulation by directly providing the audio signal to the MOS varactor which constitutes the resonant circuit of the local oscillation circuit) is employed. I2C or 3-wire can be applied to the interface with CPU.
