Product details
Overview
LMV824PWG4 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 medical devices.
For engineers reviewing the LMV824PWG4 datasheet, LMV824PWG4 pinout, LMV824PWG4 application, or LMV824PWG4 equivalent, key selection criteria include its rail-to-rail output swing (4.85 V at 5 V supply into 2 kΩ), –40°C to 125°C operating range, TSSOP-14 package footprint, and compatibility with single-supply systems requiring low input offset voltage (1–3.5 mV) and high CMRR (72 dB).
Technical Context
The LMV824PWG4 implements a complementary input stage enabling rail-to-rail output swing while maintaining low crossover distortion. Its internal architecture supports stable operation with capacitive loads up to 200 pF and achieves 64.2° phase margin at 5 V with 600 Ω load.
It operates across a wide common-mode input voltage range (–0.2 V to 4.3 V at 5 V supply) and provides 135 dB amplifier-to-amplifier isolation, making it suitable for multi-channel signal paths where crosstalk must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V - enables direct integration into 3.3 V and 5 V systems without level-shifting. |
| Gain Bandwidth | 5.5 MHz typ at 5 V - supports closed-loop gains up to ~55 at 100 kHz with stable phase margin. |
| Slew Rate | 1.9 V/μs typ at 5 V - sufficient for 100-kHz full-scale sine waves up to ~3 Vpp without distortion. |
| Input Offset Voltage | 1–3.5 mV max - ensures ≤0.07% error in unity-gain buffer configurations at mid-scale inputs. |
| Output Swing | 0.1 V from rails (2 kΩ load, 5 V supply) - preserves dynamic range in single-supply data acquisition front-ends. |
| Quiescent Current | 1 mA typ (all four amplifiers) - allows 4-channel buffering in sub-10-mA total system power budgets. |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin and industrial control environments. |

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 extended-temperature industrial use. | Select LMV824PWG4 when board space is constrained and full –40°C to 125°C operation is required. |
| TLV2464CDR | Higher supply current (1.4 mA), lower GBW (6.4 MHz), wider input voltage range (rail-to-rail input). | Better for rail-to-rail input applications but less optimal for ultra-low-power designs. | Choose TLV2464CDR only if input common-mode range beyond supply rails is mandatory. |
Compared with LMV824DR and TLV2464CDR, the LMV824PWG4 uniquely combines TSSOP-14 compactness, 125°C qualification, and 1 mA quiescent current - making it the preferred choice for thermally demanding, space-limited embedded systems requiring four matched op-amps.

FAQ
What is the operating temperature range of the LMV824PWG4?
The LMV824PWG4 is rated for operation from –40°C to +125°C, meeting requirements for automotive cabin modules and industrial control environments. This extended range is confirmed in the LMV8xxI device characterization section of the official TI datasheet SLOS434I, distinguishing it from the standard LMV824 variants limited to 85°C.
Does the LMV824PWG4 support rail-to-rail input?
No, the LMV824PWG4 features rail-to-rail *output* only. Its input common-mode voltage range extends from –0.2 V to 4.3 V at 5 V supply (i.e., 0.2 V below ground and 0.7 V below VCC+), but does not reach either rail. For true rail-to-rail input capability, consider alternatives like the TLV2464 series.
What is the maximum capacitive load the LMV824PWG4 can drive stably?
The LMV824PWG4 maintains stability with capacitive loads up to 200 pF when driving a 10 kΩ resistive load, as verified in Figure 18 of the TI datasheet SLOS434I. For loads exceeding 200 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to preserve phase margin.
Is the LMV824PWG4 pin-compatible with other LMV824 variants?
Yes, the LMV824PWG4 uses the standard TSSOP-14 pinout defined for the LMV824 family and matches the SOIC-14 (LMV824D) and TVSOP-14 (LMV824DGVR) variants pin-for-pin. All share identical terminal numbering and functional assignment per the "LMV824 . . . D, DGV, OR PW PACKAGE (TOP VIEW)" diagram in the datasheet.
What is the typical supply current of the LMV824PWG4 at 3.3 V operation?
At 3.3 V supply, the LMV824PWG4 draws approximately 0.85 mA typical total supply current for all four amplifiers, interpolated from the 2.7 V (0.72 mA typ) and 5 V (1.0 mA typ) data points in the ICC specification table. This value is consistent across the –40°C to 125°C range per LMV8xxI characterization.
