Key Featrues
Rail-to-Rail Output Swing: Both the operational amplifier and comparator feature output stages that swing rail-to-rail, ensuring maximum dynamic range and improved signal integrity. This capability is particularly beneficial in low-voltage applications where maximizing the usable voltage range is critical.
Wide Supply Voltage Range: The devices operate from a single supply voltage ranging from 2.4V to 7V, providing flexibility in various applications. This wide range allows for use in both low-power and standard voltage environments, making the ICs versatile across different use cases.
Internal Bandgap Reference: The MAX951 and MAX952 include an internal 1.2V ±2% bandgap reference, which enhances accuracy and stability in comparator operations. This integrated reference simplifies circuit design and reduces the need for external components, improving overall system reliability.
Unity-Gain Stable and Decompensated Op Amp: The operational amplifier is unity-gain stable and offers a decompensated option with a gain bandwidth product of 125kHz for gains ≥10V/V. This feature ensures stable operation across a wide range of gain settings, making it suitable for applications requiring precise signal amplification and filtering.
Applications
Infrared Receiver for Remote Controls: The MAX954's low-power consumption and rail-to-rail input/output capabilities make it an excellent choice for infrared receivers in remote control systems. Its ability to operate from a single 2.4V to 7V supply ensures compatibility with a wide range of consumer electronics, providing efficient signal processing for remote control applications.
Photodiode Preamplifier: The MAX954 is well-suited for photodiode preamplifiers in light-sensing applications. Its low input bias current and rail-to-rail output swing enable accurate amplification of weak photodiode signals, making it ideal for use in optical communication systems, light meters, and safety sensors.
Low-Frequency Alarm/Detector: The MAX954's ultra-low-power operation and integrated reference make it an excellent choice for low-frequency alarm and detector systems. Its ability to operate from a single supply and handle rail-to-rail signals ensures reliable performance in battery-powered safety sensors, such as smoke detectors or environmental monitoring devices.
