LM26
LM26 is Factory Preset Thermostat manufactured by National Semiconductor.
Description
The LM26 is a precision, single digital-output, low-power thermostat prised of an internal reference, DAC, temperature sensor and parator. Utilizing factory programming, it can be manufactured with different trip points as well as different digital output functionality. The trip point (TOS) can be preset at the factory to any temperature in the range of
- 55°C to +110°C in 1°C increments. The LM26 has one digital output (OS/OS/US/US), one digital input (HYST) and one analog output (VTEMP). The digital output stage can be preset as either open-drain or push-pull. In addition, it can be factory programmed to be active HIGH or LOW. The digital output can be factory programmed to indicate an over temperature shutdown event (OS or OS) or an under temperature shutdown event (US or US). When preset as an overtemperature shutdown...
