MAX999AAUK+T Linear - Comparators

Linear - Comparators are commonly used in many fields such as data processing, communications, and control systems. The MAX999AAUK+T from Maxim Integrated is a high-speed linear-comparator with precision voltage references. This device operates within a wide range of power supplies, from 3.3V up to 5.5V, with a typical gain tolerance of 1V/V. The MAX999AAUK+T has an integrated voltage-sensing isolated bias network and provides a low offset voltage and a minimum common-mode rejection ratio (CMRR) of 140dB. The device also has an open-collector output and can be used with digital and analog signals. Furthermore, the device has an active-high enable input, allowing it to be disabled when not in use.The MAX999AAUK+T is designed to be used in applications such as linear and nonlinear control systems, digital logic circuits, switch-mode power supplies, and other demanding low-voltage applications. In these applications, the MAX999AAUK+T must be used in conjunction with other components such as comparators, voltage references, and amplifiers to ensure the desired performance. It can also be used in patch-cord assemblies and other systems requiring high-speed and accurate voltage comparisons.The principal of operation for the MAX999AAUK+T is based on linear differential input comparisons. It combines the advantages of a high-speed comparator and a non-linear amplifier. The device uses a differential input, provided by two voltage references, to compare the difference between an input voltage of an external device and the reference voltage.Internally, the MAX999AAUK+T amplifies the differential voltage, offsetting it to allow for extremely fast transitions between high and low signals. The device has an open-collector output, allowing it to switch between a high logic output and a low logic output, depending on the difference between the two input voltages. When the input voltage is greater than the reference voltage, the device will switch to a high logic output, and when the input voltage is less than the reference voltage, the device will switch to a low logic output.The MAX999AAUK+T is designed to operate at very high speeds, up to a maximum frequency of 350kHz, with a nominal propagation delay of 3ns. This device also has a low quiescent current of 350 µA, making it suitable for low-power applications, as well as a low input bias current of 25 pA.Overall, the MAX999AAUK+T provides solutions for high-speed linear comparison applications. The device\'s wide range of operating voltages, combined with its open-collector output, low offset voltage, and high common-mode rejection ratio (CMRR) make it an ideal choice for those seeking a reliable and accurate linear-comparator.
