Product details
Overview
LMV824PWRE4 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 sensor interfaces and battery-powered data acquisition systems.
For engineers reviewing the LMV824PWRE4 datasheet, LMV824PWRE4 pinout, LMV824PWRE4 application, or LMV824PWRE4 equivalent, key selection considerations include its TSSOP-14 package footprint, –40°C to 125°C operating range, rail-to-rail output swing down to 100 mV from rails (at 2 kΩ load), and compatibility with single-supply 2.5–5.5 V systems requiring low distortion and no crossover artifacts.
Technical Context
The LMV824PWRE4 integrates four independent high-fidelity op-amps sharing a common 2.5–5.5 V single supply. Its input stage supports common-mode voltage down to ground, and its output stage drives loads to within 100 mV of VCC+ and GND under 2 kΩ conditions - critical for maximizing dynamic range in low-voltage ADC driver and active filter stages.
Designed for stability with capacitive loads up to 200 pF and resistive loads ≥600 Ω, the device features 135 dB amplifier-to-amplifier isolation and 64.2° phase margin at 5 V, ensuring robust performance in multi-channel signal chains without crosstalk-induced errors or oscillation risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V single supply - enables direct interface with Li-ion, 3.3 V, and 5 V logic domains without level shifting. |
| Gain Bandwidth | 5.5 MHz typical at 5 V - supports stable closed-loop operation up to ~500 kHz with unity-gain compensation. |
| Slew Rate | 1.9 V/μs typical at 5 V - preserves fidelity of fast transients in sensor amplification and active anti-aliasing filters. |
| Output Swing | Rail-to-rail: 0.1 V from GND and 0.15 V from VCC+ at 2 kΩ load - maximizes usable output voltage range in 3.3 V systems. |
| Input Offset Voltage | 1 mV typical, 4 mV max over –40°C to 85°C - ensures <±1 LSB error in 10-bit ADC front-ends with gain ≤10. |
| Supply Current | 1 mA typical for all four amplifiers at 5 V - enables ultra-low quiescent power in always-on monitoring circuits. |
| Operating Temperature | –40°C to 125°C - qualified for automotive cabin and industrial control environments without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824DR | SOIC-14 package; same electrical specs but larger footprint and higher thermal resistance (θJA = 86°C/W vs. 113°C/W for PW). | Preferred for prototyping or high-reliability industrial boards where hand-soldering or rework is required. | Select LMV824DR when board assembly uses through-hole or SOIC-reflow processes and thermal margin >20°C is available. |
| TLV2464IPW | Higher supply current (1.4 mA typ), lower GBW (6.4 MHz), and wider offset range (2 mV typ); specified only to 105°C. | Better suited for cost-sensitive consumer applications where extended temperature range is not required. | Choose TLV2464IPW only if design operates strictly within –40°C to 105°C and can tolerate +40% higher quiescent power. |
Compared with LMV824DR and TLV2464IPW, the LMV824PWRE4 provides optimal balance of miniaturization (TSSOP-14), thermal performance (113°C/W), and guaranteed 125°C operation - making it the preferred choice for production automotive and industrial designs where board area and temperature resilience are critical.

FAQ
What is the maximum operating temperature specification for LMV824PWRE4?
The LMV824PWRE4 is rated for operation from –40°C to +125°C ambient temperature. This extended range is confirmed in the "Recommended Operating Conditions" table of the official TI datasheet SLOS434I, and applies specifically to the LMV824I-grade devices in PW packaging - matching the LMV824PWRE4 orderable part number.
Does LMV824PWRE4 support true rail-to-rail input?
No, LMV824PWRE4 does not support rail-to-rail input. Its input common-mode voltage range extends to GND (VCC−) but only up to VCC+ – 0.3 V. The datasheet specifies VICR = –0.3 V to 4.3 V at 5 V supply - meaning the input cannot safely reach the positive rail, though the output does swing rail-to-rail.
What is the typical supply current for LMV824PWRE4 at 3.3 V operation?
At 3.3 V supply and 25°C, LMV824PWRE4 draws approximately 0.85 mA typical total supply current for all four amplifiers. This value is interpolated from the 2.7 V (0.72 mA typ) and 5 V (1.0 mA typ) ICC specifications in the datasheet's 2.7-V and 5-V electrical characteristics tables.
Is LMV824PWRE4 pin-compatible with LMV824DR?
Yes, LMV824PWRE4 is pin-compatible with LMV824DR. Both are quad op-amps in 14-pin packages (TSSOP-14 and SOIC-14 respectively) with identical pin assignments per the "LMV824 . . . D, DGV, OR PW PACKAGE (TOP VIEW)" diagram in the datasheet - enabling drop-in replacement where board layout accommodates the smaller TSSOP footprint.
What is the minimum load resistance LMV824PWRE4 can drive while maintaining rail-to-rail output swing?
LMV824PWRE4 maintains rail-to-rail output swing down to 100 mV from each rail when driving ≥2 kΩ loads. For 600 Ω loads, output swing degrades to within 130 mV of GND and 200 mV of VCC+, as specified in the 5-V electrical characteristics table under VO (output swing) test conditions.
