The TC1025CEPA series belongs to the linear-comparators family. It is used to compare two analog voltages and gives a logic output. It is mainly intended for comparing the two input signals with possible accuracy ups to 14 bit in ideal circumstances. The device features an extremely low offset as well as a low input bias current. The output of the device will be either logic low (0V) or logic high (5V) when the conditions are met. This device is suitable for applications ranging from precision data converters to function cruse control.

In terms of its working principle, the TC1025CEPA series has two identical linear-comparator input amplifiers which compare the amplitude of their respective input signals. If the input voltages are the same, the output of the device will be 0V (low state). If the two inputs are different, the output will be 5V (high state). The hysteresis behavior of the device is defined with the INH pin, while the operational amplifier gain can be adjusted with the INL pin. These parameters help to control the threshold of the output level.

The main application field of the TC1025CEPA series lies in the fields of precision data conversion. The device can be used for data conversion in A/D systems and D/A systems. For example, it can be used to compare the value of the analog signals to reference signals for applying data conversion to signals such as temperature, pressure, and so on. Apart from data conversion, the device can be used in motor control systems, DC to DC converters, and other applications that require analog-to-digital and digital-to-analog conversion.

The TC1025CEPA series is a highly-integrated device with excellent accuracy. With its low offset, low input bias current and fixed gain characteristics, it is well suited for precision data conversion in a wide range of applications such as motor control, process control, medical systems, and more. Moreover, the hysteresis and operational amplifier gain features provide a wide range of flexibility for the design engineer in the form of easy adjustment of the threshold of the output level.
