The LTC1540IS8#PBF is a high-performance, micropower comparator with an on-chip reference manufactured by Linear Technology. This precision device is designed for use in systems where low power consumption and space-saving are critical considerations. With its ultra-low quiescent current and small footprint, the LTC1540IS8#PBF is ideal for portable and battery-powered applications as well as space-constrained designs.

Key Features

• Low Power: The LTC1540IS8#PBF boasts a quiescent current of only 0.6µA, which is significantly lower than that of conventional comparators, making it a perfect choice for power-sensitive designs.
• Precision Reference: An integrated 1.182V ±1% reference voltage provides a stable and accurate threshold for comparison, reducing the need for external components.
• Wide Input Voltage Range: The comparator operates over a wide single supply voltage range of 2V to 11V or dual supplies of ±1V to ±5.5V, allowing for flexible design options.
• Internal Hysteresis: Built-in hysteresis improves noise immunity and prevents oscillation without the need for external components.
• Robust Output Stage: The push-pull output stage can drive loads directly without requiring an external pull-up resistor.
• Operating Temperature Range: The device is specified for operation from -40°C to 85°C, ensuring reliable performance in a wide range of environments.

Applications

The LTC1540IS8#PBF is versatile and can be used in a variety of applications.
