Key Features
- Wide 1.65V to 5.5V supply range enables direct use across 1.8V, 3.3V, and 5V logic systems without level translation
- Ultra-low bias current of 50nA maximum (5nA typical at 25C) minimizes loading on high-impedance signal sources in precision sensing applications
- Open-drain outputs allow easy wire-OR bus configurations and direct interfacing to multiple logic voltage domains with a single external pull-up resistor
Applications
The PLM393LVDR is designed for threshold detection, window comparator, and zero-crossing detection circuits in battery-powered and low-voltage IoT systems. Its wide supply range and ultra-low bias current make it ideal for comparator stages in portable instrumentation, sensor signal conditioning, and wearable electronics. The open-drain output configuration simplifies multi-device bus arbitration and level translation in mixed-voltage digital systems.

Frequently Asked Questions
What is the supply voltage range of the PLM393LVDR?
The PLM393LVDR operates from a 1.65V to 5.5V single-supply voltage range. This wide range makes it directly compatible with modern low-voltage logic systems including 1.8V, 2.5V, 3.3V, and 5V supply rails, eliminating the need for level shifters in mixed-voltage designs common in IoT and portable applications.
What type of output does the PLM393LVDR have?
The PLM393LVDR features open-drain outputs, which require an external pull-up resistor to the desired logic high voltage. This output type allows the outputs of multiple comparators to be wire-ORed together on a shared bus and enables interfacing to logic supplies different from the comparator's own supply voltage, providing flexible system design options.
What is the input bias current specification of the PLM393LVDR?
The PLM393LVDR has a maximum average bias current (IIB) of 50nA and a typical bias current of 5nA at 25 degrees Celsius. This extremely low input current minimizes the loading on high-impedance signal sources such as resistor dividers, piezoelectric sensors, and photodetectors, making the comparator suitable for precision low-power sensing applications.
What package does the PLM393LVDR come in?
The PLM393LVDR is available in an 8-pin SOIC package (JESD-30 code R-PDSO-G8) with a plastic/epoxy body. This surface-mount package is widely compatible with standard PCB assembly processes and provides a compact footprint for dual comparator functionality. It was introduced in July 2020 as a modern low-voltage commodity comparator solution.
What is the input offset voltage of the PLM393LVDR?
The PLM393LVDR has a maximum input offset voltage of 2500µV (2.5mV). This specification defines the worst-case voltage difference between the two inputs needed to switch the output state. For applications requiring high precision threshold detection, this offset must be accounted for in the circuit design or calibrated out in software.
