Low power consumption radio tuner IC designed for disaster situations.
With the spread and high performance of smartphones and IoT devices, reducing power consumption has become a major challenge. We have developed the "TNR24GF," which reduces power consumption by approximately 50% compared to conventional radio tuner ICs. This product achieves a current consumption of 8 mA, allowing it to operate for over 120 hours on a single AA battery. Conventional analog tuner ICs required about 30 peripheral components, but by utilizing CMOS processes and analog technology, we have integrated most of these components into the IC itself, significantly reducing the number of parts. As a result, we are simultaneously achieving waste reduction and improved energy efficiency.
