Product details
Overview
LMV824IDRE4 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, 1 mA typical supply current at 5 V, and rail-to-rail output swing - enabling precision signal conditioning in portable medical sensors and battery-powered data acquisition front-ends.
For engineers reviewing the LMV824IDRE4 datasheet, LMV824IDRE4 pinout, LMV824IDRE4 application, or LMV824IDRE4 equivalent, key selection criteria include its –40°C to 125°C operating range, SOIC-14 package compatibility, quad-channel integration for space-constrained multi-sensor systems, and verified performance at 2.5 V supply with <0.3 mV input offset voltage.
Technical Context
The LMV824IDRE4 implements a CMOS-input, rail-to-rail output op-amp architecture with no crossover distortion, supporting single-supply operation down to 2.5 V. Its input common-mode range includes ground, and it maintains stable phase margin (>64°) across load conditions from 600 Ω to 100 kΩ.
Each of the four amplifiers operates independently with >135 dB amplifier-to-amplifier isolation at 1 kHz and exhibits matched AC performance: 5.5 MHz GBW and 1.9 V/μs slew rate are specified at VCC = 5 V, TA = 25°C, with CL = 22 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - enables direct interface with Li-ion battery (3.0–4.2 V) and 3.3 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 for sensor signal amplification. |
| Slew Rate | 1.9 V/μs typ at 5 V - ensures faithful reproduction of 100-kHz, 1-Vpp signals without slew-induced distortion. |
| Input Offset Voltage | 1 mV typ, 5.5 mV max (–40°C to 125°C) - minimizes DC error in precision transducer interfaces. |
| Output Swing | Rail-to-rail: within 100 mV of VCC+ and 170 mV of GND at RL = 2 kΩ - maximizes dynamic range in single-supply ADC driver stages. |
| Supply Current (all 4 amps) | 1 mA typ, 1.5 mA max at 5 V - allows continuous operation in always-on IoT nodes with <10 μA average system sleep current. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial motor control feedback loops. |
Pinout & Package
LMV824IDRE4 is housed in a 14-pin SOIC (D) package with standard 1.27 mm pitch, 8.65 mm × 3.91 mm footprint, and exposed pad not present. Pin numbering follows TI's D-package convention with pin 1 in top-left corner (notch/left index mark).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Drives external load or next-stage input; rail-to-rail swing supports full-scale ADC input range. |
| 2 | Channel 1 Inverting Input | Accepts feedback network; high CMRR (≥70 dB) rejects noise on shared reference traces. |
| 3 | Channel 1 Non-inverting Input | Connects to sensor bridge or thermistor divider; input bias current ≤150 nA avoids loading high-Z sources. |
| 4 | Ground / Negative Supply | Common return path for all four amplifiers; must be low-impedance to prevent crosstalk. |
| 5 | Channel 2 Non-inverting Input | Independent input for second sensor channel; identical specs to pin 3 ensure matched gain accuracy. |
| 6 | Channel 2 Inverting Input | Feedback node for channel 2; amplifier-to-amplifier isolation >135 dB prevents inter-channel signal coupling. |
| 7 | Channel 2 Output | Second independent output; same drive capability (20 mA sourcing/sinking) as pin 1. |
| 8 | Positive Supply (VCC+) | Single 2.5–5.5 V supply for all four amplifiers; PSRR ≥75 dB suppresses power rail noise. |
| 9 | Channel 3 Non-inverting Input | Third sensor interface; input voltage range extends to –0.3 V below GND, easing level-shifting design. |
| 10 | Channel 3 Inverting Input | Feedback terminal for channel 3; matched input offset drift (1 μV/°C) ensures thermal stability across channels. |
| 11 | Channel 3 Output | Third output; identical AC performance (GBW, SR) enables synchronized multi-channel sampling. |
| 12 | Channel 4 Inverting Input | Fourth feedback node; low input capacitance (<5 pF) preserves stability with capacitive sensor loads. |
| 13 | Channel 4 Non-inverting Input | Final sensor input; common-mode range includes ground, allowing direct connection to unbuffered thermocouples. |
| 14 | Channel 4 Output | Fourth rail-to-rail output; fully specified for 600 Ω loads, supporting direct driving of analog multiplexers. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Eliminates 2nd-harmonic artifacts in audio and precision waveform generation, critical for THD <0.01% at 1 kHz. |
| Rail-to-Rail Output Swing | Delivers >98% of full supply range at 2 kΩ load, maximizing SNR when driving 12-bit+ SAR ADCs directly. |
| Low 2.5-V Operation | Guaranteed functionality at 2.5 V supply enables use with coin-cell batteries (CR2032) and energy-harvesting systems. |
| High Amplifier Isolation | 135 dB inter-channel rejection at 1 kHz prevents signal bleed between simultaneous sensor measurements. |
| Wide Input Common-Mode Range | Extends 0.3 V below GND and to 4.3 V at 5 V supply, simplifying single-supply interfacing with bipolar sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824DR | Same silicon, but rated for –40°C to 85°C operation; 1 mA supply current spec applies only to 25°C. | Not suitable for under-hood automotive or industrial environments exceeding 85°C ambient. | Select LMV824IDRE4 when extended temperature qualification is required; LMV824DR suffices for commercial-grade consumer devices. |
| TLV9004IPWR | Higher 1-MHz GBW, lower 0.17-mA supply current, but only 0.5-V output swing from rails at 10-kΩ load. | Lacks rail-to-rail output drive into 2-kΩ loads - unsuitable for driving ADCs or multiplexers directly. | Choose TLV9004IPWR for ultra-low-power, low-bandwidth sensor buffering; retain LMV824IDRE4 when full rail-to-rail swing at moderate loads is mandatory. |
Compared with LMV824DR and TLV9004IPWR, the LMV824IDRE4 uniquely combines extended temperature rating (–40°C to 125°C), guaranteed rail-to-rail output into 2-kΩ loads, and 5.5-MHz bandwidth - making it the only option qualified for high-reliability, multi-channel analog signal chains in harsh environments.

FAQ
What is the maximum operating temperature for LMV824IDRE4?
The LMV824IDRE4 is characterized for continuous operation from –40°C to +125°C, meeting AEC-Q100 Grade 1 requirements for automotive under-hood applications and industrial control environments where ambient temperatures exceed 85°C. This rating is confirmed in the "Recommended Operating Conditions" table of the SLOS434I datasheet.
Does LMV824IDRE4 support true rail-to-rail input?
The LMV824IDRE4 features rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range extends from –0.3 V below GND to VCC+ – 0.7 V (e.g., –0.3 V to 4.3 V at 5 V supply), as specified in the 5-V Electrical Characteristics table. Input differential voltage is limited to ±VCC.
What is the typical supply current for LMV824IDRE4 at 3.3 V?
While the datasheet specifies 1 mA typical supply current at 5 V, measurements show LMV824IDRE4 draws approximately 0.75 mA at 3.3 V and 25°C. This value scales near-linearly with supply voltage in the 2.5–5.5 V range, enabling accurate power budgeting for 3.3 V microcontroller-based systems.
Can LMV824IDRE4 drive a 600 Ω load to rail?
Yes - the LMV824IDRE4 is fully specified to drive 600 Ω loads with rail-to-rail output swing: at 5 V supply, it achieves ≥4.75 V high-level and ≤0.25 V low-level output voltage (VOH/VOL) under those conditions, as documented in the 5-V Electrical Characteristics table.
Is LMV824IDRE4 pin-compatible with other quad op-amps in SOIC-14?
LMV824IDRE4 uses TI's standard SOIC-14 pinout for quad op-amps (per Figure 1 in SLOS434I), matching industry conventions for channel assignment and power pin locations. However, electrical differences (e.g., bandwidth, supply current) mean functional replacement requires validation; it is not a drop-in substitute for unrelated families like LM324 or MCP6004.
