Overview
The LMV7272TLX/NOPB is a dual low-power analog comparator from Texas Instruments, housed in an 8-pin DSBGA package. It operates on a single supply voltage ranging from 1.8 V to 5.5 V with a typical quiescent current of 27 uA per channel. The device features rail-to-rail inputs and push-pull outputs capable of sourcing or sinking 34 mA. Key electrical specifications include a maximum input offset voltage of 4 mV, a response time of 1.8 us, and operation across a temperature range of -40°C to +85°C.
Feature Summary
- Dual-channel architecture providing two independent general-purpose comparators within a compact footprint.
- Rail-to-rail input capability allows signal processing near both supply rails without level shifting.
- Push-pull output stage delivers defined logic levels and sufficient drive current for direct interfacing.
Applications
- Battery-powered portable electronics requiring minimal standby current consumption
- Threshold detection circuits in industrial monitoring systems
- Voltage supervision and reset generation in embedded microcontroller designs
Procurement Notes
Verify the specific suffix TLX against the manufacturer's official documentation to confirm tape-and-reel packaging and pinout configuration. Ensure the operating environment remains within the specified -40°C to +85°C range to maintain guaranteed performance parameters. Cross-reference the datasheet revision history for any updates to electrical characteristics or recommended operating conditions prior to finalizing procurement orders.
Selection Notes
Select this component when a dual-comparator solution is required in space-constrained applications. The low power consumption makes it suitable for battery-operated devices where efficiency is critical. Verify that the 1.8 V minimum supply voltage aligns with the system's available power rails. Consider the DSBGA-8 package constraints during PCB layout to ensure adequate thermal dissipation and mechanical stability.
Part Context
This part belongs to the LMV727x series of low-voltage, low-power comparators designed for cost-sensitive and portable applications. It shares architectural similarities with other members like the LMV7275 but offers dual channels instead of a single unit. The series emphasizes high speed relative to its power consumption, making it a standard choice for general-purpose signal comparison tasks in consumer and industrial electronics.
FAQ
What is the output type of the LMV7272TLX/NOPB?
The device features a push-pull output stage, allowing it to actively drive both high and low logic levels without requiring external pull-up resistors.
Does the LMV7272 support rail-to-rail input signals?
Yes, the comparator inputs are rail-to-rail, enabling accurate comparison of signals that extend close to the positive and negative supply voltages.
