The LM26 is an accurate, single digital output, low-power thermostat internal reference, DAC, temperature sensor and comparator composed. With factory programming, it can manufacture different trigger points as well as different digital output functions. Trip point (T OS) can be pre-set at the factory for any temperature range from -55°C to +110°C in 1°C increments. The LM26 has a digital output (OS/^OS/US/^US), a digital input (HYST), and an analog output (V temperature). The digital output stage can be preset to open or push-pull. In addition, it can be programmed high or low at the factory. The digital output can be programmed at the factory to represent an overtemperature shutdown event (OS or ^OS) or a temperature-based shutdown event (US or ^US). When the overheating shutdown preset (^OS) will become low, indicating that the mold temperature is preset internally T OS is high, when the temperature is lower than (T OS - T HYST). Similarly, when an undertemperature shutdown (US) is preprogrammed, it goes high, indicating that the temperature below T becomes lower when above (T US + T HYST). Its typical hysteresis, T HYST, can be set to 2°C or 10°C and state control for the HYST pin. The AV temperature analog output provides an output slope of a voltage proportional to the temperature, A - 10.82mV/°C.
