Overview
The LMV7291MG/NOPB is a single-channel analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5 V and consumes 14 µA of operating current. The device features rail-to-rail input capability and push-pull output. Key electrical parameters include a response time of 1.8 µs, an input offset voltage (Vos) of 4 mV, and an input bias current (Ib) of 10 nA. Common-mode rejection ratio (CMRR) is 78 dB, while power supply rejection ratio (PSRR) is 80 dB. The input offset current (Ios) is specified at 200 pA. It functions in temperatures from -40°C to +85°C and is housed in an SC-70-5 package.
Feature Summary
- Single-channel general-purpose analog comparator with rail-to-rail input capability
- Push-pull output stage for direct logic interface compatibility
- Low power consumption of 14 µA suitable for battery-operated applications
- Operates on a wide single-supply voltage range from 1.8 V to 5 V
Applications
- Battery-powered monitoring systems requiring low quiescent current
- Threshold detection circuits in portable consumer electronics
- General-purpose signal comparison in industrial control modules
- Voltage level shifting interfaces between different logic families
Procurement Notes
Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific packaging configuration. Confirm the SC-70-5 package variant matches the PCB footprint requirements. Check the manufacturer datasheet for the latest thermal characteristics and absolute maximum ratings before finalizing the design. Ensure the operating temperature range of -40°C to +85°C aligns with the intended environmental conditions.
Selection Notes
Select this component when a single comparator with rail-to-rail inputs is required for low-voltage systems. The 1.8 V minimum supply voltage makes it suitable for modern portable devices. Consider the 1.8 µs response time for applications not requiring high-speed switching. The push-pull output simplifies interfacing with digital logic without additional pull-up resistors. Evaluate the 4 mV offset voltage against the precision requirements of the specific application circuit.
Part Context
This device belongs to the LMV7291 series of single comparators from Texas Instruments. It is designed as a low-power alternative to higher-speed comparators. The SC-70-5 package provides a compact solution for space-constrained designs. The NOPB suffix indicates a lead-free and RoHS-compliant manufacturing process. It serves as a fundamental building block for simple threshold detection tasks in mixed-signal circuits.
