Product details
Overview
LMV824IPWRE4 from Texas Instruments is a quad, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 5.5 V), low-power applications. It delivers 5.5 MHz gain bandwidth, 1.9 V/μs slew rate, and 1 mA typical supply current at 5 V - enabling precision signal conditioning in space-constrained portable electronics such as medical sensors and battery-powered instrumentation.
For engineers reviewing the LMV824IPWRE4 datasheet, LMV824IPWRE4 pinout, LMV824IPWRE4 application, or LMV824IPWRE4 equivalent, key selection considerations include its –40°C to 125°C operating range, TSSOP-14 package footprint, rail-to-rail output swing down to 100 mV from rails (at 2 kΩ load), and compatibility with single-supply systems requiring high CMRR (≥70 dB) and low input offset voltage (≤3.5 mV).
Technical Context
The LMV824IPWRE4 integrates four independent amplifiers sharing a common 2.5–5.5 V single-supply rail, with input common-mode range extending to ground and output swing within 100 mV of VCC+ and GND. Its internal architecture eliminates crossover distortion and supports stable operation with capacitive loads up to 22 pF when driving 600 Ω loads.
Each amplifier features matched AC performance: 5.5 MHz unity-gain bandwidth, 64.2° phase margin, and 135 dB amplifier-to-amplifier isolation at 1 kHz - critical for multi-channel sensor front-ends where crosstalk and settling time directly impact measurement fidelity.
Key Specifications

| 4IN− | Amplifier 4 inverting input | Configurable as summing node for analog averaging of four sensor outputs before digitization. |
| 4IN+ | Amplifier 4 non-inverting input | Accepts calibrated reference voltage; matched input bias current (≤30 nA) avoids offset drift in ratiometric designs. |
| GND/VCC− | Ground / negative supply | Single ground reference for all channels; requires low-impedance plane beneath thermal pad for thermal stability. |
| 3IN+ | Amplifier 3 non-inverting input | Enables simultaneous monitoring of three-phase motor currents with fourth amp used for fault detection. |
| 3IN− | Amplifier 3 inverting input | Connects to shunt resistor high-side; input voltage range extends to –0.3 V below GND for overcurrent sensing headroom. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824DR | SOIC-14 package, –40°C to 85°C rating, identical electrical specs except wider temp range not guaranteed. | Preferred for commercial-grade industrial controls where extended temperature is unnecessary and board space permits larger SOIC footprint. | Select LMV824DR when cost sensitivity outweighs thermal robustness and PCB area constraints are relaxed. |
| TLV2464IDR | Higher 6.4 MHz GBW, lower 0.65 mV VIO, but 2.7–6 V supply range and 1.2 mA ICC - less optimal for 2.5 V or battery-critical designs. | Better suited for higher-precision, higher-bandwidth applications like active filter banks where 2.5 V operation is not required. | Choose TLV2464IDR only if design mandates sub-millivolt offset or >5.5 MHz bandwidth and operates ≥2.7 V. |
Compared with LMV824DR and TLV2464IDR, the LMV824IPWRE4 uniquely combines 2.5 V minimum supply, 125°C operation, and TSSOP-14 compactness - making it the sole option for thermally demanding, space-constrained, ultra-low-voltage embedded systems where long-term reliability cannot be compromised.

FAQ
What is the maximum operating temperature specification for LMV824IPWRE4?
The LMV824IPWRE4 is characterized for continuous operation from –40°C to +125°C ambient temperature. This extended range is validated per the LMV8xxI device grade and confirmed in the Absolute Maximum Ratings table, where TJ(max) = 150°C and θJA = 113°C/W for the PW package - ensuring reliable function in automotive under-hood and industrial motor-drive environments. The LMV824IPWRE4 datasheet specifies performance limits across this full range.
Does LMV824IPWRE4 support true single-supply operation with input signals at ground potential?
Yes, LMV824IPWRE4 supports true single-supply operation with input common-mode voltage ranging from –0.3 V to VCC+ – 0.2 V (at 25°C), explicitly including ground (0 V). This is confirmed in the "Common-mode input voltage range" parameter (VICR) in the 5-V Electrical Characteristics tables, enabling direct interface with grounded sensors like thermistors or bridge circuits without level-shifting circuitry.
What is the output drive capability of LMV824IPWRE4 at 5 V supply?
At 5 V supply, LMV824IPWRE4 delivers ±20 mA output current (sourcing/sinking) with 0.17 V low-level and 4.75 V high-level swing into 600 Ω, and ±12 mA into 2 kΩ with 0.1 V low-level and 4.85 V high-level swing. These values are specified in the 5-V Electrical Characteristics table under "Output current" and "Output swing" parameters, confirming robust drive for ADC drivers and LED biasing in low-power systems.
Is LMV824IPWRE4 pin-compatible with other packages in the LMV824 family?
No, LMV824IPWRE4 (TSSOP-14, PW package) is not pin-compatible with LMV824D (SOIC-14) or LMV824DGVR (TVSOP-14), despite identical pin count and function mapping. Mechanical differences - including body size (5.0 × 4.4 mm vs. 8.65 × 3.91 mm), lead pitch (0.65 mm vs. 1.27 mm), and thermal pad presence - require unique PCB footprints. Pinout order matches per the top-view diagram, but physical layout is not interchangeable.
What is the typical input-referred voltage noise density of LMV824IPWRE4?
The LMV824IPWRE4 exhibits a typical input-referred voltage noise density of 42 nV/√Hz at 1 kHz and 5 V supply, as specified in the "Vn" parameter of the 5-V Electrical Characteristics table. This value remains consistent across the LMV8xxI temperature grade (–40°C to 125°C), enabling low-noise amplification of weak sensor signals such as thermocouples or piezoelectric elements without degrading system SNR.
