Product details
Overview
LPV7215MFX/NOPB from Texas Instruments is a micropower, CMOS-input, rail-to-rail input/output (RRIO), push-pull output comparator optimized for ultra-low-power battery operation. It delivers 580 nA supply current at 1.8 V, 4.5 µs propagation delay with 100-mV overdrive, and operates across −40°C to 125°C - enabling use in precision low-voltage sensing circuits such as IR receivers and window detectors.
For engineers reviewing the LPV7215MFX/NOPB datasheet, LPV7215MFX/NOPB pinout, LPV7215MFX/NOPB application, or LPV7215MFX/NOPB equivalent, key selection criteria include its sub-1-µA quiescent current, rail-to-rail input common-mode range (−0.1 V to V+ + 0.1 V), push-pull output capable of ±17 mA drive, and guaranteed operation down to 1.8 V supply.
Technical Context
The LPV7215MFX/NOPB employs a CMOS differential input stage with femtoampere-level input bias current (<±400 fA) and 120 dB open-loop gain, enabling high-precision threshold detection without external bias networks. Its push-pull output uses break-before-make MOS switching to eliminate shoot-through current and supports direct TTL/CMOS interfacing without pull-up resistors.
Propagation delay varies with overdrive (4.5–30 µs) and supply voltage (1.8–5.5 V), while input offset voltage remains tightly controlled (±0.3 mV typical, ±8 mV max over temperature). Common-mode rejection exceeds 62 dB and PSRR reaches 82 dB, ensuring robust performance in noisy single-supply systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7011DBVR | Higher supply current (650 nA typ), slower propagation (12 µs @ 100 mV), same SC70-5 package | Less suitable for multi-year battery life; acceptable where delay >10 µs is tolerable | Choose TLV7011DBVR only if cost sensitivity outweighs power/performance requirements |
| MAX9021AXK+T | Higher supply current (1.1 µA), wider supply range (1.6–5.5 V), SOT23-5 package only | Not available in SC70; requires PCB redesign; better for 1.6 V ultra-low-voltage edge cases | Select MAX9021AXK+T only when 1.6 V minimum supply is mandatory and SC70 footprint is not required |
Compared with TLV7011DBVR and MAX9021AXK+T, the LPV7215MFX/NOPB offers the lowest quiescent current and fastest propagation delay in SC70 packaging - making it optimal for space- and energy-constrained designs where timing precision and longevity are critical.

FAQ
What is the maximum operating temperature for the LPV7215MFX/NOPB?
The LPV7215MFX/NOPB is specified to operate continuously from −40°C to +125°C. This extended temperature range is validated per JEDEC standards and supports deployment in automotive under-hood, industrial control, and outdoor IoT environments. All electrical characteristics in the datasheet-including propagation delay, offset voltage, and output drive-are guaranteed across this full range.
Does the LPV7215MFX/NOPB require an external pull-up resistor on its output?
No, the LPV7215MFX/NOPB features a true push-pull output stage that actively drives both high and low states. Unlike open-drain comparators, it does not require an external pull-up resistor-reducing component count, PCB area, and power loss. The output can source up to 17 mA and sink up to 19 mA at 5 V, enabling direct interface with logic inputs, LEDs, or small actuators.
What is the input common-mode voltage range of the LPV7215MFX/NOPB?
The LPV7215MFX/NOPB supports a rail-to-rail input common-mode voltage range from −0.1 V to V+ + 0.1 V, verified across all supply voltages (1.8–5.5 V) and temperatures (−40°C to 125°C). This allows direct connection to sensors, resistive dividers, or DAC outputs operating near ground or supply rails without level-shifting circuitry.
Can the LPV7215MFX/NOPB operate from a 1.8-V supply?
Yes, the LPV7215MFX/NOPB is fully specified and guaranteed to operate at 1.8 V - its minimum rated supply voltage. At 1.8 V, it delivers 580 nA typical supply current, 4.5 µs propagation delay (H→L) with 100-mV overdrive, and rail-to-rail output swing (1.63 V high, 88 mV low at 500 µA load). This makes it ideal for coin-cell and energy-harvesting systems.
What package type is used for the LPV7215MFX/NOPB?
The LPV7215MFX/NOPB is packaged in a 5-pin SC70 (DCK) package measuring 2.00 mm × 1.25 mm.
