Product details
Overview
LMV824DRE4 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 battery-powered sensors and medical instrumentation.
For engineers reviewing the LMV824DRE4 datasheet, LMV824DRE4 pinout, LMV824DRE4 application, or LMV824DRE4 equivalent, key selection criteria include its rail-to-rail output swing (4.85 V high / 0.17 V low at 5 V, RL = 600 Ω), –40°C to 85°C operating range, SOIC-14 package, and compatibility with single-supply systems requiring low input offset voltage (1–4 mV) and high CMRR (≥70 dB).
Technical Context
The LMV824DRE4 integrates four independent amplifiers in a single SOIC-14 package, each featuring an input common-mode range extending to ground and rail-to-rail output capability. Its architecture eliminates crossover distortion and supports stable operation with capacitive loads up to 22 pF when configured for 40-dB closed-loop gain.
It operates across a 2.5–5.5 V supply range and maintains specified performance over temperature (–40°C to 85°C). Electrical characteristics - including 5.5 MHz GBW, 1.9 V/μs slew rate, and 135 dB amplifier-to-amplifier isolation - are validated under 5 V conditions with RL ≥ 2 kΩ and CL = 22 pF.
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 single-supply systems without level-shifting circuitry. |
| Gain Bandwidth | 5.5 MHz typ at 5 V - supports stable closed-loop operation up to ~100 kHz with unity-gain stability margin. |
| Slew Rate | 1.9 V/μs typ at 5 V - allows faithful reproduction of signals with <100 ns rise time in buffer or gain stages. |
| Output Swing | 0.17 V to 4.85 V at 5 V, RL = 600 Ω - delivers >96% rail utilization for maximum dynamic range in ADC driver or sensor interface roles. |
| Input Offset Voltage | 1–4 mV over –40°C to 85°C - ensures ≤20 mV error in 10× gain configurations without trimming. |
| Supply Current | 1 mA typ (all four amps) at 5 V - enables ultra-low quiescent power in always-on monitoring circuits. |
| CMRR | ≥70 dB over full temperature range - rejects common-mode noise from shared supply rails or noisy PCB environments. |
Pinout & Package
LMV824DRE4 is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package, 3.9 mm × 8.65 mm footprint, with standard 1.27 mm pitch. Pin 1 is marked by a beveled corner or dot; device orientation follows TI's D-package top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Amplifier 1 output | Drives external load or next stage; rail-to-rail swing supports full-scale interfacing with SAR ADCs. |
| 1IN− | Amplifier 1 inverting input | Accepts feedback or differential signal; input bias current ≤150 nA minimizes resistor-induced offset. |
| 1IN+ | Amplifier 1 non-inverting input | High-impedance node for sensor or reference connection; common-mode range includes ground. |
| VCC+ | Positive supply rail | Single 2.5–5.5 V supply input; decoupling capacitor required within 1 cm for stability. |
| 2IN+ | Amplifier 2 non-inverting input | Independent channel input; identical specs to Channel 1 enable matched multi-channel filtering. |
| 2IN− | Amplifier 2 inverting input | Supports differential configuration with 135 dB inter-channel isolation to prevent crosstalk. |
| 2OUT | Amplifier 2 output | Provides second independent buffered output; same drive strength (20 mA sourcing/sinking) as Channel 1. |
| 4OUT | Amplifier 4 output | Final channel output; pin-compatible with LMV822/821 families for scalable design reuse. |
| 4IN− | Amplifier 4 inverting input | Enables 4-channel active filter banks or multi-sensor signal conditioning on one IC. |
| 4IN+ | Amplifier 4 non-inverting input | Ground-referenced input capability simplifies single-supply transducer interfacing. |
| GND/VCC− | Ground / negative rail | Reference node for all channels; must be low-impedance return path to avoid PSRR degradation. |
| 3IN+ | Amplifier 3 non-inverting input | Third channel input; supports simultaneous processing of multiple analog inputs without multiplexing delay. |
| 3IN− | Amplifier 3 inverting input | Configurable for summing, difference, or instrumentation amplifier topologies. |
| 3OUT | Amplifier 3 output | Third independent output; identical electrical specs ensure consistent channel-to-channel performance. |

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 | Identical electrical specs and SOIC-14 pinout; differs only in tape-and-reel packaging (2500/reel vs. 2500/reel for DRE4) and RoHS compliance status (DRE4 is lead-free per TI spec). | No functional difference; both rated for –40°C to 85°C operation and share identical thermal and electrical behavior. | Select LMV824DR if legacy Pb-based assembly is required; otherwise LMV824DRE4 is preferred for RoHS-compliant production. |
| TLV2464CDR | Higher supply current (1.4 mA typ), lower GBW (6.4 MHz), and wider input offset range (±2 mV max); uses same SOIC-14 package but different pin mapping for power/ground. | Not pin-compatible: GND is Pin 7, VCC+ is Pin 14 - requires PCB redesign. Better DC precision but higher power consumption. | Choose TLV2464CDR only when tighter initial offset (<2 mV) is mandatory and layout revision is acceptable. |
Compared with LMV824DR, LMV824DRE4 offers identical performance with enhanced environmental compliance; versus TLV2464CDR, it provides lower power and guaranteed pinout compatibility but trades minor DC precision for cost and layout efficiency.

FAQ
What is the operating temperature range for LMV824DRE4?
The LMV824DRE4 is characterized for operation from –40°C to +85°C. This range is validated across all key parameters including input offset voltage, gain bandwidth, and output swing. It does not support the extended –40°C to +125°C range offered by the LMV824I variants (e.g., LMV824IDR), and must be derated outside the specified ambient limits to maintain reliability.
Is LMV824DRE4 pin-compatible with other LMV8xx devices?
Yes, LMV824DRE4 shares the same SOIC-14 pinout as all LMV824 variants (e.g., LMV824DR, LMV824D), including identical assignments for VCC+, GND/VCC−, and all eight input/output terminals. However, it is not pin-compatible with LMV822 (SOIC-8) or LMV821 (SOT-23-5/SC-70-5) due to differing channel count and package size.
Does LMV824DRE4 support true rail-to-rail input?
No, LMV824DRE4 features rail-to-rail *output* swing but its input common-mode voltage range extends only to VCC– (ground) and up to ~4.3 V at 5 V supply - not to VCC+. The datasheet specifies VICR = –0.3 V to 4.3 V (at 5 V), meaning the non-inverting input cannot accept signals within ~200 mV of VCC+ without degraded CMRR or increased offset.
What is the maximum capacitive load LMV824DRE4 can drive without instability?
LMV824DRE4 is stable driving up to 22 pF capacitive load when configured with 40-dB closed-loop gain (e.g., gain-of-100) and proper PCB layout. For unity-gain configurations, stability requires CL ≤ 15 pF unless external compensation (e.g., series resistor at output) is added. Exceeding these limits risks peaking or oscillation, especially with long traces or unshielded cables.
Can LMV824DRE4 be used in single-supply sensor interface circuits?
Yes, LMV824DRE4 is explicitly designed for single-supply operation from 2.5 V to 5.5 V. Its input common-mode range includes ground and its rail-to-rail output allows full-scale signal swing - making it ideal for interfacing with resistive bridges, thermistors, and current-output sensors without dual supplies or level-shifting networks.
