Product details
Overview
LMV824IPWR from Texas Instruments is a quad, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 5.5 V) and 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 battery-powered sensors and medical instrumentation.
For engineers reviewing the LMV824IPWR datasheet, LMV824IPWR pinout, LMV824IPWR application, or LMV824IPWR 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 of rails (at 2 kΩ load), and absence of crossover distortion in audio and sensor front-end designs.
Technical Context
The LMV824IPWR integrates four independent high-fidelity op-amps on a single die, each featuring input common-mode voltage range extending to ground and rail-to-rail output capability. Its internal architecture eliminates crossover distortion and supports stable operation with capacitive loads up to 200 pF when configured with appropriate feedback networks.
Designed for single-supply systems, it maintains >70 dB CMRR and PSRR across 2.5–5.5 V supply range, with amplifier-to-amplifier isolation exceeding 135 dB at 1 kHz - critical for multi-channel data acquisition where crosstalk must be minimized in mixed-signal PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - enables direct interface with Li-ion, 3.3 V, and 5 V logic without level-shifting. |
| Gain Bandwidth Product | 5.5 MHz typ at 5 V - supports closed-loop gains up to ~55 at 100 kHz with stable phase margin (>64°). |
| 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 mV typ, 5.5 mV max (–40°C to 125°C) - ensures <1 LSB error in 12-bit ADC driver applications. |
| Output Swing | Within 100 mV of rails (2 kΩ load, 5 V supply) - maximizes dynamic range in single-supply signal chains. |
| Supply Current per Amp | 250 μA typ (1 mA total for all four amps at 5 V) - extends battery life in always-on sensor nodes. |
| 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 | Same electrical specs but rated for –40°C to 85°C; SOIC-14 package (larger footprint, higher θJA). | Not suitable for under-hood automotive or extended-temperature industrial deployments. | Select LMV824DR only if ambient temperature remains ≤85°C and board space permits SOIC. |
| TLV9004IPWR | Lower 0.6 mA supply current, 1 MHz GBW, and rail-to-rail I/O - optimized for ultra-low-power, lower-bandwidth use cases. | Better for battery life-critical IoT endpoints; insufficient for 100-kHz sensor bandwidth requirements. | Choose TLV9004IPWR when power budget is tighter than bandwidth needs, e.g., wireless sensor nodes with 10-year battery goals. |
Compared with LMV824DR and TLV9004IPWR, the LMV824IPWR uniquely balances extended temperature operation, 5.5 MHz bandwidth, and TSSOP-14 compactness - making it the only option among the three qualified for automotive cabin and high-accuracy industrial signal chains requiring both speed and thermal robustness.

FAQ
What is the maximum operating temperature for LMV824IPWR?
The LMV824IPWR is characterized for operation from –40°C to +125°C, making it suitable for under-dash automotive modules and industrial control cabinets where ambient temperatures exceed 85°C. This rating is confirmed in the "Recommended Operating Conditions" table of the SLOS434I datasheet, and applies specifically to the 'I' grade (industrial/automotive) variant denoted by the 'I' in LMV824IPWR.
Does LMV824IPWR support rail-to-rail input?
No, the LMV824IPWR does not support rail-to-rail input. Its input common-mode voltage range extends to ground (VCC−) but only up to VCC+ – 0.3 V, as specified in the "Common-mode input voltage range" parameter (VICR = –0.3 V to 4.3 V at 5 V supply). However, its rail-to-rail output capability remains fully functional across the full supply range.
What is the typical supply current for LMV824IPWR at 3.3 V?
At 3.3 V supply, the LMV824IPWR draws approximately 0.85 mA typical total supply current (212.5 μA per amplifier), interpolated from the 2.7 V (0.72 mA typ) and 5 V (1.0 mA typ) data points in the "ICC" specification tables. This value is confirmed in Figure 3 ("Supply Current vs Supply Voltage") of the SLOS434I datasheet, which shows monotonic increase across the 2.5–5.5 V range.
Can LMV824IPWR drive a 600 Ω load effectively?
Yes, the LMV824IPWR can drive a 600 Ω load with rail-to-rail output swing: at 5 V supply, it delivers 4.75 V high-level and 0.17 V low-level output (typical), corresponding to 4.58 Vpp swing. Output current capability is ±20 mA (sourcing/sinking), well above the 8.3 mA peak required for 4.58 Vpp into 600 Ω, ensuring minimal distortion in line-driver or active-filter applications.
Is LMV824IPWR pin-compatible with LMV824DR?
Yes, LMV824IPWR and LMV824DR share identical pinout and electrical functionality - both are quad op-amps in 14-pin packages (TSSOP-14 vs SOIC-14) with matching terminal assignments. However, they are not drop-in replacements due to differing package dimensions, thermal characteristics, and temperature ratings; PCB layout must be redesigned for TSSOP-14 mechanical fit and solder profile.
