TEA6100 Overview
The TEA6100 is a FM/IF system circuit intended for microputer controlled radio receivers. The circuit includes highly sensitive analogue circuitry. The digital circuitry, including an I2C bus, controls the analogue circuitry and the AM/FM tuning and stop information for the microputer.
