Introduction

MAX995EUD+T is a voltage comparator that belongs to the Linear-Comparators category, which is a type of integrated circuit (IC) used for comparing two analogue voltages present at the two vertex points in the circuit (inverting and non-inverting). It is based on an open loop gain of the amplifier, which is ideally infinite, however in the case of MAX995EUD+T, it is kept constant by using an adjustable resistor in the amplifier’s feedback path.

Application Field and Working Principle

The MAX995EUD+T can be used in a variety of applications, such as level detection, temperature sensing, proximity sensing and other applications that require an IC to compare two voltages and make decisions based on the result of the comparison. It has a few key features:

• It has High Common-Mode voltage range from -0.3V to +26V
• It offers Low Input Offset voltage of 3mV
• It has a Low Power Consumption of 5mA
• It is provided in a space-efficient 8-pin DIP and 8-pin SOIC packages
• It is RoHS- and Datasheet-compliant
• It has a Signetics CMOS process technology

The MAX995EUD+T operates on the principle of comparing two voltages (V+ and V-). When the voltage at V+ exceeds the voltage at V-, the output takes the form of a high signal (logic “1”). Similarly, when the voltage at V- exceeds the voltage at V+, the output takes the form of a low signal (logic “0”). The outputs of the MAX995EUD+T are available as CMOS compatible digital signals.

The MAX995EUD+T utilizes a resistor network with an adjustable resistor to match the amplifier’s open loop gain. The adjustment of the resistor can be done manually or digitally — for example the use of a control signal. The amplifier of the MAX995EUD+T is internally biased and provides a voltage gain greater than 250. The time needed to reach the steady-state output is usually within microseconds.

The MAX995EUD+T is designed to be used in temperature sensing, proximity sensing and position sensing systems, as well as in industrial robotics control systems, electrical and electronic power systems, test and measurement instrumentation and related industrial applications. The MAX995EUD+T is a precision voltage mixer, where V+ is the input voltage and V- is an adjustable voltage. By adjusting the external resistor, V+ will be compared to V-, and the result of the comparison is the output signal.

Conclusion

MAX995EUD+T belongs to the Linear-Comparator family of integrated circuits. It is made from the Signetics CMOS process technology and provides a high common-mode voltage range. It can be used in applications such as temperature sensing, proximity sensing, and level detection, where it compares two different voltages and generates an output signal. The MAX995EUD+T provides a low power consumption, a low input offset voltage, and is available in a space-efficient 8-pin DIP and 8-pin SOIC packages.
