Overview
The LM2901PWRG4 is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin TSSOP surface-mount package. It operates on a single or dual power supply ranging from 2 V to 36 V. The device features an open-collector output type and delivers a typical response time of 1.3 µs. It supports a maximum output current of 20 mA per channel with a typical quiescent current of 2.5 mA. The input offset voltage is typically 7 mV, and the input bias current is 250 nA. The component functions within a temperature range of -40 °C to +125 °C.
Feature Summary
- Integrates four independent differential comparators into a single compact surface-mount package for space-constrained designs.
- Provides open-collector outputs compatible with CMOS and TTL logic families, facilitating direct interfacing with digital systems.
- Operates across a wide supply voltage range from 2 V to 36 V, supporting both single and dual power configurations.
Applications
- General-purpose analog signal comparison in industrial control circuits
- Voltage monitoring and threshold detection in battery-powered devices
- Over-voltage and under-voltage protection circuits
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the TSSOP-14 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet revision date to ensure compatibility with your design constraints.
Selection Notes
Select this component when a quad comparator configuration is required with low power consumption and wide supply voltage flexibility. The open-collector output allows for wired-AND connections and level shifting. Consider the 1.3 µs response time against application speed requirements. Verify that the 20 mA sink capability suffices for the load connected to each output channel.
Part Context
The LM2901 series belongs to Texas Instruments' family of low-power, low-offset voltage quad comparators. It serves as a modern replacement for legacy parts like the LM139 and LM339, offering improved performance in a smaller TSSOP package. The 'G4' suffix denotes green/RoHS-compliant manufacturing processes without antimony trioxide.
Replacement Considerations
LM2901DR: Pin-compatible SOIC-14 alternative with similar electrical characteristics. LM2901IDR: Industrial grade variant with tighter offset voltage specifications. LM339PW: Legacy pin-compatible option, though performance parameters may differ slightly.
