Преобразователи температуры в цифровой код
Фирма Analog Devices поставляет большой набор цифровых датчиков температуры с различными интерфейсами (SPI, I2C, однопроводной и с широтно-импульсным сигналом на выходе). От очень простых датчиков с точностью до ±0.5°C до высокоинтегрированных цифровых температурных датчиков с многоканальными АЦП и источником опорного напряжения - все они датчики упрощают процесс разработки системы. Цифровые датчики не требуют внешних схем линеаризации и преобразования. Рабочий диапазон датчиков может достигать -40°C...+150°C; эти датчики применяются в самых различных областях, в том числе измерительной технике, в автомобилях, компьютерах, системах связи и бытовой технике.
