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
