The LM26 is an accurate, single digital output, low power thermostat internal reference, DAC, temperature sensor and comparator composition. Using factory programming, it can manufacture different trigger points as well as different digital output functions. Transition point (T_OS），Any temperature range from -55 °C to +110 °C can be preset at the factory 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 as open-drain or push-pull. In addition, it can be programmed high or low in the factory. The digital output can be factory programmed to represent an overtemperature shutdown event (OS or ^OS) or a temperature-dependent shutdown event (US or ^US). When the thermal shutdown preset (^OS), it will become low, indicating that the mold temperature is preset internally_targetThe OS is high when the temperature is below_（TOS_{- T}HYST ）。 Similarly, when an undertemperature shutdown (US) is pre-programmed, it goes high, indicating that the temperature_BelowThe US becomes lower when the temperature is above_（TUnited States_{+ T}HYST ）。 Its typical hysteresis, T_HYST，Can be set to 2°C or 10°C and status control of the HYST pin. AV_temperatureThe analog output provides a voltage proportional to temperature, with a - 10.82mV/°C output slope.

Detailed ordering information is available in some sections. For other fractional shareholdings, information on minimum order eligibility with distributors or sales representatives of National Semiconductor. The LM26 is currently available in a 5-pin SOT-23 package.
