Overview

The LV3400M is a filter IC designed for FM multiplex broadcast reception and is used in combination with the Sanyo LC72700 demodulation/error correction IC. The adoption of switched capacitor (SCF) technology means that frequency adjustment is not required and that the LV3400M provides stable operation.

Features

• Adjustment-free, due to the use of SCF technology.

• Few external components are required.

Functions

• 76 kHz band-pass filter (Gaussian filter)

• 54 kHz high-pass filter

• 125 kHz low-pass filter

• Anti-aliasing filter

• Limiter circuit
