LV3401M

Overview

The LV3401M is a filter IC for FM multiplex broadcasting reception which is used in combination with demodulation and

error correction IC (LC72700 series). The use of switched capacitor filter (SCF) technique obviates the need for frequency

adjustment and ensures stable operation.

Functions

• 76kHz BPF (Gaussian filter)

• 54kHz HPF

• 125kHz LPF

• Anti-aliasing filter

• Limiter circuit
