Product details
Overview
LPV7215MGX/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 LPV7215MGX/NOPB datasheet, LPV7215MGX/NOPB pinout, LPV7215MGX/NOPB application, or LPV7215MGX/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 at 5 V), and guaranteed operation at 1.8 V supply.
Technical Context
The LPV7215MGX/NOPB employs a CMOS input stage with PMOS/NMOS differential pair, delivering femtoampere-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 internal break-before-make push-pull output eliminates pull-up resistors and enables direct TTL/CMOS interfacing without external components.
Propagation delay is overdrive- and supply-voltage-dependent: 4.5 µs (H→L) and 6.6 µs (L→H) at 100-mV overdrive and 1.8 V, degrading to 12–15 µs at 10-mV overdrive. Gain is fixed at 120 dB, and input offset voltage remains tightly bounded (±0.3 mV typ, ±6 mV max at 25°C).

Applications
| RC Timers | Window Detectors |
|---|---|
Use Scenario: Precision timing circuits generating fixed-duration pulses using resistor-capacitor charge/discharge cycles. IC Role / Device Role / Timing Role: Comparator compares capacitor voltage against stable reference to trigger reset or toggle state. Use Value: Sub-µA quiescent current extends timer battery life; 4.5 µs delay enables accurate µs–ms resolution without calibration drift. |
Use Scenario: Monitoring analog sensor outputs (e.g., temperature, pressure) to detect out-of-range conditions. IC Role / Device Role / Timing Role: Dual-comparator configuration (with external resistors) defines upper/lower voltage thresholds. Use Value: Rail-to-rail input allows full utilization of sensor's output swing; low offset minimizes false alarms near trip points. |
| IR Receivers | Alarm Circuits |
Use Scenario: Demodulating modulated infrared signals in remote control receivers or proximity sensors. IC Role / Device Role / Timing Role: High-gain comparator detects weak AC-coupled IR photodiode signals amid ambient noise. Use Value: 120 dB gain rejects common-mode interference; femtoampere input bias prevents signal loading on high-Z photodiode node. |
Use Scenario: Low-power security or environmental alarm systems requiring long-term standby with fast wake-up response. IC Role / Device Role / Timing Role: Threshold detector triggering microcontroller interrupt or buzzer driver upon fault condition. Use Value: 1.8 V minimum supply enables direct connection to LiFePO₄ or primary cell; 580 nA sleep current preserves multi-year battery life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211IDBVR | Higher supply current (900 nA), slower propagation (12 µs @ 100 mV), same SC70-5 package | Less suitable for <1-µA systems; acceptable where margin exists in battery budget | Choose TLV7211IDBVR only if higher speed is not required and layout reuse is critical |
| NCS2200SN2T1G | Open-drain output, 1.1 µA supply current, wider supply range (0.85–6 V), SOT-23-5 | Requires external pull-up; better for mixed-voltage logic interfacing but adds power overhead | Select NCS2200SN2T1G when interfacing with 1.2 V or 1.8 V logic families needing open-drain flexibility |
Compared with TLV7211IDBVR and NCS2200SN2T1G, LPV7215MGX/NOPB uniquely combines sub-600 nA supply current, push-pull output, and rail-to-rail input in SC70 - making it optimal for ultra-low-power, single-supply, space-constrained detection systems where external components must be minimized.

FAQ
What is the minimum supply voltage for reliable operation of the LPV7215MGX/NOPB?
The LPV7215MGX/NOPB is fully specified and guaranteed to operate down to 1.8 V, with electrical characteristics validated at 1.8 V, 2.7 V, and 5 V. At 1.8 V, it maintains 580 nA supply current, 4.5 µs propagation delay (H→L), and rail-to-rail input functionality - making it ideal for single-cell lithium or alkaline systems. Operation below 1.8 V is not characterized or recommended.
Does the LPV7215MGX/NOPB require an external pull-up resistor on its output?
No. The LPV7215MGX/NOPB features a true push-pull output stage capable of sourcing and sinking current (±17 mA at 5 V), eliminating the need for an external pull-up resistor. This reduces component count, saves PCB area, and avoids the power waste associated with static pull-up current - a key advantage over open-drain comparators like the NCS2200SN2T1G.
What is the input bias current specification for the LPV7215MGX/NOPB, and why does it matter?
The LPV7215MGX/NOPB exhibits input bias current of −40 fA typical (at VCM = 1.6 V, 25°C), enabled by its CMOS input stage. This ultra-low leakage allows direct interfacing with high-impedance sources - such as photodiodes, thermistors, or RC timing networks - without signal attenuation or offset errors caused by bias current flowing through source resistance.
Can the LPV7215MGX/NOPB drive capacitive loads, and how does load affect propagation delay?
Yes, the LPV7215MGX/NOPB can drive capacitive loads without instability, and propagation delay is unaffected by capacitance. However, large capacitive loads may cause output waveform distortion (e.g., step artifacts during falling edges), as shown in Figures 29–30 of the datasheet. Resistive loads do slightly reduce falling-edge delay (~2 µs at 100 kΩ), but this is secondary to overdrive and supply voltage effects.
Is the LPV7215MGX/NOPB pin-compatible with other comparators in the LPV72xx family?
Yes - the LPV7215MGX/NOPB shares identical 5-pin SC70 (DCK) pinout and function mapping with LPV7211, LPV7212, and LPV7213 variants. All feature V+, VIN−, VIN+, V−, and VOUT on pins 5, 4, 3, 2, and 1 respectively. This enables drop-in substitution where performance requirements (e.g., propagation delay, supply current) align across variants.
