Key Featrues
Single-Supply Voltage Range (2.5V to 5.5V): This feature allows the device to operate efficiently from a single power supply, making it ideal for portable and battery-powered applications. It simplifies the power design and reduces the need for additional components, enhancing overall system efficiency.
Low Quiescent Current (340µA): The device draws minimal current during operation, which significantly extends battery life in power-sensitive applications. This feature is particularly beneficial for devices like smart card readers and remote controls, where energy efficiency is critical.
Rail-to-Rail Output Swing: Both the operational amplifier and comparator outputs can swing close to the supply rails, maximizing the dynamic range of the signal. This ensures accurate signal processing in low-voltage applications and improves performance in sensor signal detection and photodiode preamps.
Fast 185ns Propagation-Delay Comparator: The high-speed comparator enables rapid decision-making in applications like keyless entry and zero-crossing detectors. This feature enhances system responsiveness and is crucial for time-sensitive operations.
Internal Precision Reference (1.230V ±1%): The integrated precision reference provides a stable voltage source with low temperature drift (8ppm/°C), reducing the need for external reference components. This improves accuracy in applications such as instruments, terminals, and bar-code readers, while also saving board space.
