The LM2903QTH-13 is a two-input, quad-comparator linear-comparator chip produced by STMicroelectronics®. It is an integrated circuit (IC) designed to compare two analog voltages and drives digital outputs when one voltage exceeds the other. It has a wide range of applications in digital systems, medical devices, automotive systems, home appliances, and other industrial and consumer products.The LM2903QTH-13 is designed to compare two analog voltages and drive digital outputs when one voltage is greater than, less than, or equal to the other. The device is designed with two independent voltage-comparator (VC) channels, where each channel has two complementary outputs, one for each comparator, that can be independently programmed or enabled. The LM2903QTH-13 also includes two independent reference trackers, one for each VC channel, and an adjustable Hysteresis switch tuned for power supply rejection. The LM2903QTH-13 offers a wide range of features in a small package, making it a great choice for small form-factor designs. All of the device’s features are packaged in a VFQFN-8 package, providing a small footprint and simple board design. The low-power, low-noise design allows the device to operate in a wide temperature range and, when combined with its enhanced thermal protection architecture, makes the LM2903QTH-13 suitable for use in automotive, industrial and consumer applications.The device’s comparator outputs are TTL/CMOS-compatible and can be programmed to respond to input voltage ranges from 0-5V, allowing for a wide range of application possibilities. The comparator outputs are also highly configurable, allowing for flexible control from the user, and can be programmed to respond as either an open-drain output or as push-pull.The LM2903QTH-13 also includes an adjustable hysteresis switch, which helps reject power supply noise and transients. This allows the device to maintain stability by damping the effects of sudden changes in power supply voltage. The adjustable hysteresis switch also helps reduce the rate of false triggers, further enhancing the device’s stability and performance.The LM2903QTH-13 linear-comparator chip is an ideal solution for many application scenarios, such as data acquisition, motor control, process control, automotive applications, and medical devices. Its versatile design and small package size make it a great choice for designers looking to conserve board space. With its range of features and innovative design, the LM2903QTH-13 is a great choice for designers seeking a robust, low-power linear-comparator solution.
