TDA7540AE - Brand New STMicroelectronics IC Chips
-
Description
The TDA7540AE is a high-performance tuner circuit with a stereo decoder designed for AM/FM car radios. It integrates various components such as a mixer, IF amplifier, demodulator, stereo decoder, quality detection, ISS filter, and PLL synthesizer into a single chip. The use of BICMOS technology enables the implementation of multiple tuning functions with minimal external components.
Specifications and Features
