Description

The CD7613 is a monolithic integrated circuit designed for the portable AM/FM radio or AM/FM clock radios. An AM/FM radio IC (Integrated Circuit) is a specialized semiconductor device designed to receive and process radio signals in both the AM (Amplitude Modulation) and FM (Frequency Modulation) frequency bands. These ICs are commonly used in radio receivers to tune in to different radio stations and provide audio output. AM/FM radio ICs are widely used in various radio receiver applications, including portable radios, car radios, clock radios, and other consumer electronics.

Features

1. Portable AM/FM 1-chip radio

2. Wide operating supply voltage range:
Vcc=3V~12V (Approximately) (Depending on the internal regulator tolerance)

3. Recommended operating supply voltage :
Vcc=4.5V~9V On using AC line as an internal shunt regulator mode , it is possible to use low cost application without a transformer (approximately 42mA).

4. IF AMP gain is determined by DC Voltage appeared at IC Pin16

5. Power output: Po=0.28W (Min.) at THD=10% (Vcc=5.5V/8Ω )
