Product details
Overview
LPV7215MF/NOPB from Texas Instruments is a single-channel, micropower, rail-to-rail input/output comparator with push-pull output stage, designed for ultra-low-power battery-operated systems. It delivers 580 nA supply current at 1.8 V, 4.5 µs propagation delay (100 mV overdrive), and operates across −40°C to 125°C - enabling use in precision window detectors and IR receiver front-ends.
For engineers reviewing the LPV7215MF/NOPB datasheet, LPV7215MF/NOPB pinout, LPV7215MF/NOPB application, or LPV7215MF/NOPB equivalent, key selection criteria include its sub-1 µA quiescent current, rail-to-rail CMVR (−0.1 V to V+ + 0.1 V), push-pull drive capability (17 mA sourcing / 19 mA sinking at 5 V), and guaranteed operation down to 1.8 V supply.
Technical Context
The LPV7215MF/NOPB uses a CMOS input stage with PMOS/NMOS differential pair, delivering femtoamp-level input bias current (−40 fA typical) and rail-to-rail common-mode input range (CMVR = −0.1 V to V+ + 0.1 V). Its high open-loop gain (120 dB) suppresses output oscillation near zero-differential inputs.
Its push-pull output employs break-before-make timing control to eliminate shoot-through current, enabling efficient direct interfacing with TTL/CMOS logic without external pull-up resistors - critical for minimizing system-level power in always-on sensing nodes.

Applications
| RC Timers | Window Detectors |
|---|---|

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 SOT-23-5 package | Less suitable for sub-5 µs timing-critical RC timers; acceptable for general-purpose low-power monitoring | Select TLV7011DBVR only if cost sensitivity outweighs speed/power trade-off and layout reuse is prioritized |
| MAX9021AUT+T | Higher supply current (1.1 µA), wider supply range (1.6–5.5 V), SC70-5 package only | Not pin-compatible; requires PCB redesign; better for ultra-low-voltage (1.6 V) edge cases | Choose MAX9021AUT+T only when operating below 1.8 V is mandatory and SC70 footprint is acceptable |
Compared with TLV7011DBVR and MAX9021AUT+T, the LPV7215MF/NOPB offers the lowest propagation delay per nanoamp of supply current - making it optimal for battery-constrained systems requiring both speed and longevity, without sacrificing rail-to-rail input or push-pull drive.

FAQ
What is the minimum supply voltage for reliable operation of the LPV7215MF/NOPB?
The LPV7215MF/NOPB is fully specified and guaranteed to operate down to 1.8 V supply voltage across the full temperature range (−40°C to +125°C), with all electrical characteristics validated at this rail - making it ideal for single-cell lithium or two-cell alkaline systems where voltage droop occurs.
Does the LPV7215MF/NOPB require external pull-up resistors on its output?
No - the LPV7215MF/NOPB features a true push-pull output stage that actively drives both high and low states. This eliminates the need for external pull-up resistors, reducing power loss, component count, and PCB area compared to open-drain comparators.
Can the LPV7215MF/NOPB interface directly with 3.3-V or 5-V logic families?
Yes - the LPV7215MF/NOPB's push-pull output delivers rail-to-rail swing (e.g., 0 V to 3.3 V or 0 V to 5 V), meeting TTL and CMOS logic thresholds. At 3.3 V supply, VOH ≥ 3.15 V and VOL ≤ 0.18 V under 500 µA load, ensuring robust noise margins.
What is the input bias current specification for the LPV7215MF/NOPB, and why does it matter?
The LPV7215MF/NOPB exhibits −40 fA typical input bias current at 25°C. This ultra-low value prevents loading of high-impedance sources (e.g., thermistors, photodiodes, or RC timing networks), preserving accuracy and preventing signal distortion in precision threshold detection.
Is the LPV7215MF/NOPB available in both SOT-23 and SC70 packages?
Yes - the LPV7215MF/NOPB is orderable in 5-pin SOT-23 (DBV) and 5-pin SC70 (DCK) packages. The SOT-23 variant (LPV7215MF/NOPB) measures 2.90 mm × 1.60 mm; the SC70 variant (LPV7215IDCKR) is smaller at 2.00 mm × 1.25 mm - both share identical electrical specifications.
