Linear-Comparators are a type of electronic circuit that compares two analog or digital input signals, as well as generate an output when either of the inputs reach a set voltage, current, temperature or power threshold. The LM2903TH-13 is an example of such a comparator, featuring a wide range of comparator applications from analog to digital. This article looks at the LM2903TH-13’s application field and working principle.
The LM2903TH-13 is specifically designed for applications requiring supply current at or below 300uA, making it a great choice for low-power designs. It is suitable for a wide range of applications including personal computers, phone chargers and portable devices. Furthermore, the LM2903TH-13 can detect when an input signal reaches a specified voltage or power level, and this can be used for a variety of voltage measurements and peak power detection.
The LM2903TH-13 is also useful for non-inverting comparator applications. These applications involve doubling the input signal, inverting it and using a separate supply to power the inverter, allowing for measurements of small signals without the need for additional components. Furthermore, the LM2903TH-13 can be used for negative supply rail sensing, which allows the circuit to determine when an operator is controlling a specific device by measuring the output voltage of the device. Additionally, the LM2903TH-13 can be used for duty cycle control and frequency detection.
The LM2903TH-13 works by comparing two separated levels of voltage, or by comparing one or more voltage levels to ground. When the input signal reaches a defined voltage, the LM2903TH-13 will activate a signal indicating the exact voltage level at which the input signal reached the set voltage. This signal can then be detected and used to control circuitry or used to trigger an event. The LM2903TH-13 is also equipped with adjustable positive/negative hysteresis, meaning it can be fine-tuned to detect precise output events.
The LM2903TH-13 has several features that make it particularly well-suited for many applications. It is a single supply device, and does not require dual supplies for operation. Additionally, the LM2903TH-13 has a low-voltage offset between the inputs, so it can accurately detect small changes in input signals. The LM2903TH-13 is also designed with power-down detection, allowing the system to detect a shutdown condition and immediately begin the shutdown process.
The LM2903TH-13 is a versatile comparator intended for use in a variety of sensor-driven applications. Its low-voltage offset between the inputs and its power-down detection capabilities make it ideal for use with precision sensor systems that require a precise measurement of input signals. Furthermore, the LM2903TH-13’s adjustable positive/negative hysteresis makes it a great choice for applications that require precise control of output events.
