TechnologiesThe TEA1062NL-D16-T is an integrated telecommunications circuit manufactured by Unisonic Technologies. It is a Dual-Channel Dial Tone Detector with Filters for telephone systems, and features a DIP (Dual Inline Package) 16 interface. It is a RoHS (Restriction of Hazardous Substances) compliant product, meaning that it contains no lead or other hazardous materials. The TEA1062NL-D16-T is designed for detecting US, British, and Japanese dial tones, as well as several other country-specific tones. It features two separate adjustable gain filters for each channel, allowing for the filtering of harmonics and other noise disturbances, resulting in a greater accuracy of tone detection. Additionally, the TEA1062NL-D16-T has low power consumption, making it energy-efficient and suitable for battery powered applications. It is also designed with circuit protection circuitry, which helps protect the device from damage due to high voltages, low impedance of the telephone lines, and other environmental disturbances.
