LPV7215MG

Overview

The LPV7215MG is a single-channel analog comparator manufactured by Texas Instruments, housed in an SC-70-5 surface-mount package. It operates within a supply voltage range of 1.8 V to 5.5 V and draws a typical quiescent current of 580 nA. The device features rail-to-rail input and output capabilities, with a maximum input offset voltage of 3.4 mV and an input bias current of 1 pA. Key performance metrics include a propagation delay of 12 µs, a common-mode rejection ratio of 98 dB, and a power supply rejection ratio of 82 dB. It supports a push-pull output stage capable of sourcing or sinking up to 19 mA and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output functionality enables operation with signals extending to the supply rails.
• Ultra-low quiescent current consumption supports battery-powered applications requiring minimal power drain.
• Push-pull output architecture provides active drive capability for both high and low logic states.

Applications

• Battery-operated portable electronics
• Threshold detection circuits
• Voltage monitoring systems

Procurement Notes

Verify the specific suffix 'MG' against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the operating environment remains within the specified -40°C to +125°C temperature range to maintain guaranteed electrical parameters. Cross-reference the datasheet revision history for any updates regarding marking or assembly changes before finalizing procurement orders.

Selection Notes

Select this component when a low-power, single-supply comparator with rail-to-rail characteristics is required. The wide operating temperature range makes it suitable for industrial environments. Consider the 12 µs propagation delay when designing for high-speed signal processing, as it may limit performance in fast-switching applications compared to faster comparator alternatives.

Part Context

This part belongs to the LPV7215 series of low-voltage comparators designed for general-purpose applications. It shares functional similarities with other members of the family but differs in packaging and specific thermal ratings. The SC-70-5 package offers a compact footprint for space-constrained designs while maintaining the electrical performance standards of the broader series.
