The LM26 is a high-precision single digital output, low-power thermostat consisting of an internal reference, digital-to-analog converter, temperature sensor and comparison. Using factory programming, it can manufacture different trigger points as well as different digital output functions. This visit point (tOS)Any plant can be preset in the -55°C temperature range, in increments of 1°C to +110°C. The LM26 has a digital output (OS/^OS/US/^US), 1 digital input (HYST) and an analog output (Vtemperature)。 The digital output stage can be preset to either open drain or push-pull. In addition, it can be programmed as a high or low plant. The digital outputs can be programmed to represent plants that turn off events over temperature (OS or ^OS) or shutdown events based on temperature (US or ^US). When preset to thermal shutdown (^OS) it will become low, indicating the mold temperatureoperating systemIs preset T inside and goes to high temperature, high below (tonsoperating system- T'sHYST)。 Similarly, when shutting down pre-programmed as undertemperature (US) will not become high, indicateUnited StatesWhen the temperature is lower than T and becomes lower, the temperature is higher than (tonsUnited States+ THYST)。 Typical hysteresis, THYST,It can be set to 2°C or 10°C and pin-controlled HYST status too. VideotemperatureA temperature proportional to the analog output voltage and a -10.82mV/°C output slope are provided.
