Overview
The LMC6762BIMX/NOPB is a dual micro-power rail-to-rail input CMOS comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 15V single or ±1.35V to ±7.5V dual, with a maximum quiescent current of 20µA. The device features push-pull outputs capable of sourcing 30mA and offers a typical propagation delay of 10µs. Input offset voltage is maximized at 15mV at 5V, while input bias current remains as low as 0.04pA. Common-mode rejection ratio and power supply rejection ratio are typically 75dB and 80dB respectively. It is housed in an 8-SOIC package and functions across a temperature range of -40°C to 85°C.
Feature Summary
- Rail-to-rail input capability allows operation with signals extending to the supply rails.
- Micro-power consumption ensures minimal static current draw for battery-sensitive applications.
- Push-pull output stage provides active drive capability without requiring external pull-up resistors.
Applications
- Battery-powered monitoring systems
- Threshold detection circuits
- Low-voltage signal conditioning
Procurement Notes
Verify that the specific suffix /NOPB confirms lead-free and RoHS compliance status as per manufacturer documentation. Confirm the package variant matches the required 8-SOIC footprint dimensions. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the manufacturer part number against official distribution channels to avoid counterfeit components.
Selection Notes
Select this component when rail-to-rail input swing is necessary alongside ultra-low power constraints. The push-pull output simplifies interface design compared to open-drain alternatives. Verify that the 10µs propagation delay is sufficient for the intended switching frequency. Consider the 15mV input offset voltage tolerance for precision threshold applications.
Part Context
This device belongs to the LMC6762 family of dual comparators designed for general-purpose analog switching tasks. It utilizes CMOS technology to achieve high input impedance and low power usage. The component serves as a standard solution for voltage comparison in portable electronics where power efficiency is critical.
Replacement Considerations
LMC6762BIM is the non-reel version of this component. LMC6762BIMX is the reel version without the NOPB suffix. Verify functional equivalence if substituting with other dual comparators from different manufacturers.
