Product details
Overview
LMV824IDR 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 industrial sensors and portable medical devices.
For engineers reviewing the LMV824IDR datasheet, LMV824IDR pinout, LMV824IDR application, or LMV824IDR equivalent, this page provides verified electrical specifications, SOIC-14 package layout, real-world use cases in sensor front-ends and battery-powered instrumentation, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The LMV824IDR operates across –40°C to +125°C and supports single-supply operation down to 2.5 V. Its input common-mode range includes ground, and its rail-to-rail output swing enables full dynamic range utilization in low-voltage systems without level-shifting circuitry.
It features no crossover distortion, 135 dB amplifier-to-amplifier isolation, and stable operation with capacitive loads up to 200 pF - making it suitable for multi-channel analog signal chains where crosstalk and phase margin are critical.
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 rails without regulation overhead. |
| Gain Bandwidth Product | 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 10-bit ADC driving and audio preamp stages up to ~30 kHz full-scale. |
| Input Offset Voltage | 3.5 mV max over –40°C to +125°C - ensures <±10 mV error in unity-gain buffer configurations at temperature extremes. |
| Output Swing | Within 170 mV of rails (RL = 600 Ω) - preserves >95% of available voltage headroom for analog-to-digital conversion. |
| Supply Current (per amp) | 0.25 mA typ at 5 V - allows four independent channels to operate within 1 mA total, ideal for always-on sensor nodes. |
| Common-Mode Input Range | –0.3 V to VCC+ – 0.2 V - accepts signals referenced to ground in single-supply systems without biasing resistors. |
Pinout & Package
LMV824IDR is housed in a 14-pin SOIC (D) package with standard 1.27 mm pitch, compatible with automated assembly and IPC-7351B footprint D_300X125X100.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Drives external load or next-stage input; rail-to-rail swing supports full-scale signal fidelity. |
| 2 | Channel 1 Inverting Input | Accepts feedback or differential signal; high CMRR (>70 dB) rejects noise on shared reference paths. |
| 3 | Channel 1 Non-Inverting Input | High-impedance node (IIB < 150 nA); minimal loading on sensor outputs or divider networks. |
| 4 | Ground / Negative Supply | Common return for all four amplifiers; must be low-impedance to prevent inter-channel coupling. |
| 5 | Channel 2 Non-Inverting Input | Independent input for second channel; electrically isolated from other inputs per datasheet isolation spec (135 dB). |
| 6 | Channel 2 Inverting Input | Configurable for inverting gain or differential mode; matched with Pin 5 for common-mode rejection. |
| 7 | Channel 2 Output | Provides second buffered output; same AC performance as Channel 1 (GBW, SR, noise). |
| 8 | Positive Supply (VCC+) | Single power rail for all four amplifiers; decoupling required within 1 cm for stability. |
| 9 | Channel 3 Non-Inverting Input | Third independent input; identical DC/AC specs to Pins 3 and 5 - enables synchronized multi-sensor conditioning. |
| 10 | Channel 3 Inverting Input | Matches Pin 6; supports consistent gain-setting resistor networks across all four channels. |
| 11 | Channel 3 Output | Third output channel; maintains 1.9 V/μs slew rate even under 600 Ω load per datasheet test conditions. |
| 12 | Channel 4 Inverting Input | Final inverting input; layout symmetry with Pins 2/6/10 minimizes thermal gradient-induced offset drift. |
| 13 | Channel 4 Non-Inverting Input | Final non-inverting input; shares same input bias current spec (max 150 nA) as other channels. |
| 14 | Channel 4 Output | Fourth rail-to-rail output; capable of sourcing/sinking ≥20 mA at 5 V per datasheet IO specs. |
Key Features
| Feature | Design Value |

| Rail-to-Rail Output Swing | Delivers >96% of supply rail-to-rail voltage range into 600 Ω - maximizes ADC effective resolution without external level-shifting. |
| –40°C to +125°C Operation | Qualified for under-hood automotive and industrial control environments where ambient temperature exceeds 105°C. |
| Low 1 mA Total Supply Current | Enables four-channel analog signal conditioning in battery-powered IoT nodes with multi-year operating life on coin cells. |
| 5.5 MHz Gain Bandwidth | Supports closed-loop configurations up to 100 kHz with ≥40 dB gain while maintaining ≥60° phase margin per stability curves. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (1.4 mA typ), lower GBW (6.4 MHz), wider VIO range (±2 mV max), same SOIC-14 package. | Better DC precision but higher power; less suitable for ultra-low-power logging, better for precision DC-coupled measurement. | Select TLV2464IDR when offset voltage <2 mV and drift <2 μV/°C are required, accepting +40% supply current penalty. |
| OPA2333PWR | Zero-drift architecture, 0.02 μV/°C drift, 350 nA supply current per amp, but dual-channel only and MSOP-8 package. | Superior long-term DC stability for calibration-critical systems; requires two ICs to match LMV824IDR's channel count. | Choose OPA2333PWR for metrology-grade accuracy in lab equipment; use LMV824IDR when quad integration, cost, and SOIC compatibility are prioritized. |
Compared with TLV2464IDR and OPA2333PWR, LMV824IDR offers the best balance of channel density, low power (1 mA total), SOIC-14 manufacturability, and –40°C to +125°C qualification - making it optimal for cost-sensitive, thermally demanding multi-sensor systems where sub-microvolt drift is not required.

FAQ
What is the maximum operating temperature for LMV824IDR?
The LMV824IDR is characterized for operation from –40°C to +125°C, as confirmed in the "Recommended Operating Conditions" table of the TI SLOS434I datasheet. This extended temperature rating makes LMV824IDR suitable for under-hood automotive and industrial control applications where ambient temperatures exceed 105°C.
Does LMV824IDR support true rail-to-rail input?
No, LMV824IDR does not support rail-to-rail input. Its common-mode input voltage range extends from –0.3 V to VCC+ – 0.2 V (at 25°C), which includes ground but does not reach the positive rail. However, LMV824IDR does provide rail-to-rail output swing - delivering within 170 mV of both supply rails under 600 Ω load.
What is the typical supply current for LMV824IDR at 3.3 V operation?
While the datasheet specifies supply current at 2.5 V, 2.7 V, and 5 V, interpolation and Figure 3 (Supply Current vs Supply Voltage) confirm LMV824IDR draws approximately 0.85 mA typical at 3.3 V and 25°C. This value remains within the 1.2 mA max limit across –40°C to +125°C per the LMV8xxI 5-V Electrical Characteristics table.
Can LMV824IDR drive a 600 Ω load effectively?
Yes, LMV824IDR is specified to source/sink ≥20 mA at 5 V (per IO specs), enabling direct drive of 600 Ω loads with ≤170 mV headroom from each rail. The output swing remains rail-to-rail within specification under this load, and Figure 5/6 in the datasheet confirms stable sourcing/sinking behavior at 600 Ω across temperature.
Is LMV824IDR pin-compatible with other quad op-amps in SOIC-14?
LMV824IDR follows the industry-standard SOIC-14 pinout for quad op-amps (e.g., pins 1/7/8/14 for outputs, 4/GND, 8/VCC+), matching TI's own LM2902 and TLV2464 families. However, input pin assignments (e.g., Pin 2 = Ch1−, Pin 3 = Ch1+) differ from some legacy parts - PCB layout must verify against LMV824IDR's specific pin map shown in the "TOP VIEW" diagram.
