Overview
The LMV7291MGX/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 quiescent current. The device features rail-to-rail input capability with an offset voltage of 4 mV and input bias current of 10 nA. It provides a push-pull output stage and exhibits a response time of 1.8 µs. Common-mode rejection ratio is 78 dB, while power supply rejection ratio reaches 80 dB. Input offset current is specified at 200 pA. The component functions across a temperature range from -40°C to +85°C and is housed in a SC-70-5 package.
Feature Summary
- Rail-to-rail input architecture for extended signal range compatibility
- Push-pull output stage enabling direct load driving without external pull-up resistors
- Low power consumption suitable for battery-operated applications
Applications
- General purpose voltage monitoring
- Threshold detection circuits
- Level shifting interfaces
Procurement Notes
Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific tape-and-reel packaging configuration. Confirm that the SC-70-5 footprint matches the target PCB layout requirements. Ensure operating conditions remain within the specified 1.8 V to 5 V supply range and -40°C to +85°C temperature limits to maintain guaranteed electrical performance parameters.
Selection Notes
Select this component when a low-power, single-channel comparator with rail-to-rail inputs is required. The push-pull output simplifies circuit design by eliminating the need for external pull-up components. Consider the 1.8 µs response time for application speed requirements. The SC-70-5 package offers space efficiency for compact designs. Verify that the 4 mV offset voltage meets the precision needs of the specific threshold detection task.
Part Context
This device belongs to the LMV7291 series of analog comparators from Texas Instruments. It is designed for low-voltage, low-power applications requiring small form factors. The series utilizes advanced processes to achieve high performance with minimal current draw. The NOPB suffix indicates non-lead-containing pins and RoHS compliance. It serves as a general-purpose solution for basic comparison tasks in portable electronics.
Replacement Considerations
Consult official Texas Instruments documentation for verified pin-compatible or functionally equivalent alternatives within the LMV72xx family. Cross-reference specifications such as response time, offset voltage, and package dimensions before substitution.
