Product details
Overview
LMV824M from Texas Instruments is a quad, rail-to-rail output (RRO), low-voltage (2.5 V to 5.5 V), low-power operational amplifier with 5 MHz gain-bandwidth product, 1.4 V/µs minimum slew rate, and 3.5 mV maximum input offset voltage. It operates across –40°C to +85°C and drives 600 Ω loads within 160 mV of supply rails - ideal for battery-powered portable instrumentation and signal conditioning in space-constrained analog front-ends.
For engineers reviewing the LMV824M datasheet, LMV824M pinout, LMV824M application, or LMV824M equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical context - including rail-to-rail output swing into 600 Ω, 220 µA per amplifier quiescent current at 2.7 V, and stable performance with capacitive loads.
Technical Context
The LMV824M integrates four independent high-performance op-amp channels in a single SOIC-14 package, each featuring input common-mode range extending to ground and rail-to-rail output swing. Its architecture supports single-supply operation down to 2.5 V while maintaining 90 dB CMRR and 85 dB PSRR at 5 V.
Designed for low-noise, low-distortion signal amplification, it achieves 24 nV/√Hz input voltage noise at 1 kHz and 0.01% THD at 1 kHz with 4.1 VPP output into 10 kΩ - enabling precision DC-coupled gain stages and active filtering in portable audio and sensor interfaces.
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 systems without level-shifting. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - supports stable unity-gain buffers and closed-loop gains up to ~100 at 50 kHz. |
| Slew Rate | 1.4 V/µs min - sufficient for 100 kHz full-scale sine waves up to ~2.2 VPP without distortion. |
| Input Offset Voltage | 3.5 mV max - ensures ≤0.7% gain error in 100× non-inverting configurations at room temperature. |
| Quiescent Current | 1.0 mA typical (250 µA per amplifier) - allows four-channel amplification in sub-1 mA total system budget. |
| Rail-to-Rail Output | Swings to within 160 mV of rails at 600 Ω load - preserves dynamic range in low-voltage ADC driver applications. |
| Input Common-Mode Range | –0.3 V to 4.3 V at 5 V supply - includes ground, enabling single-supply transducer signal conditioning. |
Pinout & Package
LMV824M is housed in a 14-pin SOIC package (8.65 mm × 3.91 mm body size) with standard dual-in-line footprint and gull-wing leads. This package supports automated assembly and provides thermal resistance RθJA = 109.7 °C/W.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464AIDR | Higher supply current (420 µA per amp), wider VOS range (2.5 mV typ, 6 mV max), lower GBW (6.4 MHz). | Better DC precision but higher power; less suitable for battery-critical designs. | Choose TLV2464AIDR when tighter initial offset and higher bandwidth outweigh quiescent current concerns. |
| LMV324IDR | Lower GBW (1 MHz), slower slew rate (0.45 V/µs), higher VOS (7 mV max), same SOIC-14 package. | Cost-optimized general-purpose quad; insufficient for audio or fast sensor response. | Choose LMV324IDR only for non-critical DC amplification where bandwidth and speed are secondary. |
Compared with TLV2464AIDR and LMV324IDR, LMV824M uniquely balances 5 MHz bandwidth, rail-to-rail output, and sub-1 mA total supply current - making it optimal for portable, precision, low-voltage analog signal chains where power and performance must coexist.

FAQ
What is the maximum operating temperature for LMV824M?
The LMV824M is specified for operation from –40°C to +85°C ambient temperature. While the automotive-grade LMV824-N-Q1 variant extends to +125°C, the standard LMV824M (including LMV824M) maintains full parameter compliance only up to +85°C per its recommended operating conditions table in the TI datasheet SNOS032I.
Does LMV824M support true rail-to-rail input?
No, LMV824M does not feature rail-to-rail input. Its input common-mode voltage range extends to –0.3 V (below ground) and up to 4.3 V at 5 V supply - including ground but not reaching V+, limiting full-rail input capability. The device is explicitly specified as rail-to-rail *output* (RRO), not input.
Can LMV824M drive a 100 pF capacitive load stably?
Yes, LMV824M is characterized for stable operation with capacitive loads up to at least 100 pF, as confirmed by phase margin plots (Figure 18–25) and application notes in the datasheet. No external compensation is required for loads ≤100 pF when driving resistive loads ≥2 kΩ.
What is the typical supply current per amplifier in LMV824M at 3.3 V?
At 3.3 V supply, LMV824M draws approximately 0.85 mA total (212.5 µA per amplifier), interpolated from the 2.7 V (0.72 mA typ) and 5 V (1.0 mA typ) supply current values in Section 6.7 and 6.10 of the datasheet. This value remains well within the 1.0 mA maximum at 5 V and reflects its low-power design intent.
Is LMV824M pin-compatible with LMV324 or TLV2464?
No, LMV824M is not pin-compatible with LMV324 or TLV2464. Although all three use SOIC-14 packages, their pinouts differ: LMV824M assigns Pin 4 to V− and Pin 8 to V+, whereas LMV324 uses Pin 4 for V− and Pin 8 for V+ but has different input/output assignments for Channels C and D. TLV2464 uses a distinct pin mapping optimized for dual-supply operation.
