AS6001SP8 Datasheet – FM Stereo Audio Transmitter
FM STEREO AUDIO TRANSMITTER,I2C-BUS IC
AS6001SP8 overview
The AS6001SP8 is an FM STEREO AUDIO TRANSMITTER,I2C-BUS IC, supplied in an SOP20 package. The absolute maximum ratings table on this page lists the 5 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the AS6001SP8 pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The AS6001/AS6002 is an innovative highly integrated FM stereo transmitter. It is the first generation of FM transmitter IC designed using Accel’s patent-pending RF technology.
It consists of a stereo encoder and FM transmitter. The stereo encoder is based on signal processing to encode analog stereo audio input signal and generate a composite FM signal with MAIN, SUB and pilot signal from a 7.6MHz oscillator. The FM transmitter uses direct frequency synthesis to radiate FM wave to the air by modulating the carrier signal with the composite signal.
The AS6001/AS6002 is designed for portable application as well as general application. The 1.8V operation voltage and as low as 18mA quiescent current make it extremely suitable for portable devices such as MP3 and mobile phone. It also embeds LDO power regulator to make power supply design easy and flexible. The AS6001 has a 3-wire digital control interface for external controller easy and flexible to program and control the transmitting channel. The transmitting channel is from 87 to 108 MHz with 0.1MHz step continuous tuning. So it is suitable for China, Europe and North America.
