PROBLEM TO BE SOLVED: To provide an integrated circuit for a tuner module where an analog/ digital converter can be used for a desired purpose and the wiring pattern is not made complicated. SOLUTION: The integrated circuit for the tuner module of this invention includes: a tuner section A; and an intermediate frequency processing section B. The tuner section A is provided with a PLL circuit 5 incorporating the analog/digital converter 13. The intermediate frequency processing section B includes an AFT circuit 10 and an AGC circuit 11, an output terminal of the AFT circuit 10 and an output terminal of the AGC circuit 11 are connected to an input terminal of the PLL circuit 5 via a changeover switch 12, and an output terminal of the PLL circuit 5 can be connected to a microcomputer 19 via a 2-way bus 20.
