Product details
Overview
LMV824PWE4 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 LMV824PWE4 datasheet, LMV824PWE4 pinout, LMV824PWE4 application, or LMV824PWE4 equivalent, key selection considerations include its TSSOP-14 package, –40°C to 125°C operating range, rail-to-rail output swing down to 100 mV from rails (at 2 kΩ load), and absence of crossover distortion in audio and sensor front-end designs.
Technical Context
The LMV824PWE4 integrates four independent high-speed op-amps sharing a common 2.5–5.5 V single-supply rail. Each amplifier features input common-mode voltage range extending to ground and rail-to-rail output swing, supporting direct interfacing with ADCs and microcontroller analog inputs without level-shifting circuitry.
Its internal architecture eliminates crossover distortion and achieves stable unity-gain operation with 64.2° phase margin at 5 V and 600 Ω load. Amplifier-to-amplifier isolation exceeds 135 dB, minimizing crosstalk in multi-channel sensing systems.

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, rated for –40°C to 85°C only | Not suitable for under-hood or industrial environments requiring 125°C operation | Select LMV824PWE4 when extended temperature range and smaller TSSOP footprint are required |
| TLV2464IPW | Higher supply current (1.4 mA typ), lower GBW (6.4 MHz), wider offset range (±2 mV) | Better DC precision but higher power; not drop-in due to different input bias structure | Choose TLV2464IPW only if tighter initial offset and higher speed justify +40% supply current |
Compared with LMV824DR and TLV2464IPW, the LMV824PWE4 uniquely balances extended temperature operation, compact TSSOP-14 packaging, and sub-1.3 mA quiescent current - making it optimal for space- and power-constrained automotive and industrial edge nodes where thermal robustness is non-negotiable.

FAQ
What is the operating temperature range of the LMV824PWE4?
The LMV824PWE4 is rated for operation from –40°C to +125°C. This extended temperature range is confirmed in the LMV8xxI device specifications and distinguishes it from the standard LMV824 variants (–40°C to +85°C), making LMV824PWE4 suitable for under-hood automotive and industrial control cabinet applications where ambient temperatures exceed 85°C.
Does the LMV824PWE4 support true rail-to-rail input operation?
The LMV824PWE4 does not support rail-to-rail input - its input common-mode voltage range extends from –0.3 V below ground to 0.2 V below VCC (e.g., –0.3 V to 4.3 V at 5 V supply). However, it does provide rail-to-rail output swing within 100 mV of both rails under 2 kΩ load, which is explicitly characterized in the 5-V Electrical Characteristics table for LMV8xxI devices.
What is the maximum output current capability of each amplifier in the LMV824PWE4?
Each amplifier in the LMV824PWE4 can source or sink up to 20 mA continuously (25°C, VCC = 5 V), as specified in the 5-V Electrical Characteristics table under "IO - Output current". The actual sustained current depends on thermal conditions and load configuration; the device's θJA of 113°C/W in TSSOP-14 requires careful PCB thermal design for continuous 20-mA operation across all four channels.
Is the LMV824PWE4 pin-compatible with other LMV824 variants?
Yes - the LMV824PWE4 uses the TSSOP-14 (PW) package with identical pinout to LMV824PW, LMV824PWR, and LMV824IPWR. All share the same 14-pin functional mapping shown in the "LMV824 . . . D, DGV, OR PW PACKAGE (TOP VIEW)" diagram. Mechanical compatibility is confirmed by TI's package drawing PW0014A.
Why is the LMV824PWE4 marked as "Not Recommended for New Designs" in the datasheet?
The "Not Recommended for New Designs" notice applies to the entire LMV8xx family (including LMV824PWE4) due to TI's product lifecycle policy - indicating that newer alternatives like the TLV9064 or OPA391 are preferred for new designs. However, LMV824PWE4 remains fully qualified, in active production (per TI's 2016 Addendum), and supported with full datasheet specifications, making it viable for legacy refresh, cost-sensitive production, or applications where its specific GBW/supply current trade-off remains optimal.
