Posted on by pinout

Part Number: TEA5767

Function: Low-power FM stereo radio for handheld applications

Package: HVQFN40 Type

Manufacturer: NXP Semiconductors.

Pinouts:

TEA5767 datasheet

 

Description

The TEA5767, TEA5767HN is a single-chip electronically tuned FM stereo radio for low-voltage applications with fully integrated Intermediate Frequency (IF) selectivity and demodulation.

The radio is completely adjustment-free and only requires a minimum of small and low cost external components. The radio can be tuned to the European, US, and Japanese FM bands.

Features

1. High sensitivity due to integrated low-noise RF input amplifier

2. FM mixer for conversion to IF of the US/Europe (87.5 MHz to 108 MHz) and Japanese (76 MHz to 91 MHz) FM band

3. Preset tuning to receive Japanese TV audio up to 108 MHz

4. RF Automatic Gain Control (AGC) circuit

5. LC tuner oscillator operating with low cost fixed chip inductors

6. FM IF selectivity performed internally

7. No external discriminator needed due to fully integrated FM demodulator
