Texas Instruments LMV7219M7

Overview

LMV7219M7 from Texas Instruments is a single-channel, rail-to-rail output comparator optimized for high-speed, low-power applications. It delivers 7 ns propagation delay at 5 V supply, draws only 1.1 mA quiescent current, and supports input common-mode voltage down to −0.2 V (200 mV below ground), enabling ground-sensing in portable battery-powered systems.

For engineers reviewing the LMV7219M7 datasheet, LMV7219M7 pinout, LMV7219M7 application, or LMV7219M7 equivalent, key selection considerations include its internal 7.5 mV hysteresis, push-pull output stage, SC-70-5 package footprint, and guaranteed operation across −40°C to +85°C ambient with 105°C PCB temperature support.

Technical Context

The LMV7219M7 employs a PNP-input differential stage enabling extended common-mode range below ground, while its internal hysteresis ensures clean switching even with slow-moving inputs. Its push-pull output eliminates external pull-up resistors and enables fast 1.3 ns rise/1.25 ns fall times at 5 V.

Propagation delay remains stable across overdrive levels (7 ns at 50 mV overdrive, 9 ns at 5 mV) and temperature (−40°C to +85°C), with skew under 0.4 ns. Input bias current flows *out* of both inputs due to PNP topology, requiring careful sourcing design in high-impedance sensor interfaces.

FAQ

What is the maximum operating temperature for the LMV7219M7?

The LMV7219M7 is specified for operation from −40°C to +85°C ambient temperature, with validated reliability up to 105°C PCB temperature. Its junction temperature limit is 125°C under recommended operating conditions, and absolute maximum junction temperature is 150°C. Thermal metrics (R_θJA = 296°C/W for SC-70) enable accurate thermal design for compact layouts.

Does the LMV7219M7 require external hysteresis resistors?

No, the LMV7219M7 integrates 7.5 mV of internal hysteresis, eliminating the need for external feedback resistors in most threshold-detection applications. This simplifies PCB layout and reduces BOM cost. External hysteresis can be added using positive feedback if wider bands (>100 mV) are required, but the internal hysteresis is sufficient for noise suppression in typical high-speed sensing scenarios involving the LMV7219M7.

Can the LMV7219M7 operate from a 2.7 V supply?

Yes, the LMV7219M7 is fully specified for operation from 2.7 V to 5 V single supply. At 2.7 V, it maintains 12 ns propagation delay (typical), 0.9 mA supply current (typical), and retains rail-to-rail output swing and −0.2 V input common-mode capability. All electrical characteristics-including hysteresis (7 mV), input offset (6 mV), and output drive-are guaranteed across this full voltage range for the LMV7219M7.

What is the input bias current direction and magnitude for the LMV7219M7?

The LMV7219M7 uses a PNP-input stage, so input bias current flows *out* of both +IN and −IN pins. Typical bias current is 500 nA at 5 V and 25°C, with a maximum of 2 µA over temperature. This outward flow must be accommodated in high-impedance source designs-e.g., photodiode anodes should connect to +IN or −IN with appropriate biasing to avoid forward-biasing parasitic junctions, a key consideration in all LMV7219M7 implementations.

Is the LMV7219M7 pin-compatible with other comparators in SC-70-5 packages?

The LMV7219M7 uses standard SC-70-5 (DCK) pinout: Pin 1 = OUT, Pin 2 = V−, Pin 3 = +IN, Pin 4 = −IN, Pin 5 = V+. While physically compatible with other SC-70-5 comparators (e.g., TLV3501DBVR), functional compatibility requires verification of input topology (PNP vs. NPN), hysteresis presence, output type (push-pull vs. open-drain), and supply range. The LMV7219M7 is not a drop-in replacement for comparators lacking internal hysteresis or rail-to-rail output drive.
