IC LM567CN

Description

The LM567CN Tone Decoder IC is a precision Phase-Locked Loop (PLL) tone decoder designed to detect a specific input frequency and provide a digital output when the target tone is present. Featuring an adjustable center frequency from 0.01 Hz to 500 kHz, high noise immunity, and low false triggering, the LM567CN is ideal for tone decoding, frequency detection, FSK demodulation, ultrasonic control systems, remote controls, and communication applications.
