LTC1042CN8#PBF

LTC1042 is a monolithic CMOS window comparator manufactured using Linear Technology’s enhanced LTCMOS™ silicon gate process. Two high impedance voltage inputs, CENTER and WIDTH/2, define the middle and width of the comparison window. Whenever the input voltage, VIN, is inside the window the WITHIN WINDOW output is high. The ABOVE WINDOW output is high whenever VIN is above the window. By interchanging VIN and CENTER, the ABOVE WINDOW output becomes BELOW WINDOW and is high if VIN is below the window. Sampling techniques provide high impedance voltage inputs that can common mode to both supply rails (V+ and GND). An important feature of the inputs is their non-interaction. Also the device is effectively “chopper stabilized,” giving it extremely high accuracy over all conditions of temperature, power supply and input voltage range. It is used in application such as fault detectors, Go/No-Go testing, microprocessor power supply monitor etc.
