Frequently Asked Questions
What is the supply voltage range for the LM211DR?
The LM211DR supports a wide supply voltage range: single supply from +5V to +36V, or dual supplies from ±1.5V to ±18V. The nominal dual supply is ±15V with a maximum negative supply voltage limit of -18V, making it versatile for both low-voltage and high-voltage applications.
What is the input offset voltage of the LM211DR?
The LM211DR has a maximum input offset voltage of 3000µV (3mV). This low offset voltage ensures accurate voltage comparison with minimal error, making it suitable for precision threshold detection and analog signal processing circuits.
What package does the LM211DR come in and what are the pin dimensions?
The LM211DR is available in an 8-pin Small Outline Package (SOIC-8), designated by the JESD-30 code R-PDSO-G8. This surface-mount package offers a compact footprint ideal for space-constrained PCB designs in industrial and consumer electronics applications.
What are common applications for the LM211DR comparator?
The LM211DR is commonly used in zero-crossing detectors, window comparators, threshold detection circuits, data acquisition systems, motor control, and battery management systems. Its strobe input adds flexibility for enabling or disabling the output, making it useful in multiplexed comparator arrays and controlled switching circuits.
What is a suitable replacement or alternative for the LM211DR?
Compatible alternatives to the LM211DR include the LM311DR (single supply optimized version), LM393DR (dual comparator in SOIC-8), and LM339DR (quad comparator). These devices share similar open-collector output topology and are pin-compatible or functionally equivalent in many circuit designs.
