Product details
Overview
LMV824DE4 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, 1 mA typical supply current at 5 V, rail-to-rail output swing, and operates across –40°C to 85°C - used in portable sensor signal conditioning and battery-powered analog front-ends.
For engineers reviewing the LMV824DE4 datasheet, LMV824DE4 pinout, LMV824DE4 application, or LMV824DE4 equivalent, key selection considerations include its SOIC-14 package, quad-channel integration, rail-to-rail output capability under 2.5–5.5 V supply, and suitability for space-constrained, low-noise, single-supply signal amplification tasks.
Technical Context
The LMV824DE4 implements a CMOS input stage with rail-to-rail output architecture, enabling full-swing operation into high-impedance loads and moderate resistive loads (e.g., 2 kΩ). Its 5.5 MHz gain bandwidth and 64.2° phase margin support stable unity-gain and closed-loop configurations up to 100 kHz with minimal overshoot.
It features no crossover distortion, 42 nV/√Hz input voltage noise at 1 kHz, and amplifier-to-amplifier isolation of 135 dB - critical for multi-channel systems where crosstalk must be minimized, such as in multi-sensor data acquisition or audio preamplifier banks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to Li-ion, 3.3 V, or 5 V rails without level-shifting. |
| Gain Bandwidth Product | 5.5 MHz typ at 5 V - enables stable amplification of signals up to ~100 kHz with gain ≥10. |
| Slew Rate | 1.9 V/μs typ at 5 V - supports 100-kHz full-scale sine output up to ~1.2 VPP without distortion. |
| Output Swing | Rail-to-rail - delivers 0.1 V from VCC+ and 0.17 V from GND at 600 Ω load, maximizing dynamic range. |
| Input Offset Voltage | 1 mV typ, 4 mV max (–40°C to 85°C) - ensures ≤2 mV error in 1× gain sensor buffers. |
| Supply Current per Channel | 0.25 mA typ (1 mA total for all four amps at 5 V) - enables ultra-low quiescent power in always-on monitoring circuits. |
| Common-Mode Input Range | Includes ground (–0.2 V to 4.2 V at 5 V) - accepts single-ended signals referenced to system GND. |

Applications
| Portable Sensor Signal Conditioning | Battery-Powered Data Acquisition |
|---|---|
Use Scenario: Amplifying low-level outputs from MEMS accelerometers or thermistors in handheld medical devices. IC Role / Device Role / Timing Role: Quad buffer and gain stage - each amplifier conditions one sensor channel with matched DC performance. Use Value: Rail-to-rail output preserves full dynamic range into 12-bit SAR ADCs; 1 mA total quiescent current extends battery life beyond 1 year in sleep-active cycling. | Use Scenario: Simultaneous analog front-end for 4-channel environmental monitor (temp/humidity/pressure/gas). IC Role / Device Role / Timing Role: Four independent instrumentation-grade signal conditioners driving multiplexed ADC input. Use Value: 135 dB channel isolation prevents cross-talk between sensors; 5.5 MHz GBW supports fast settling for 10 kSPS sampling. |
| Single-Supply Audio Preamp | Industrial Process Monitoring |
Use Scenario: Low-noise microphone preamplifier in voice-controlled smart speakers operating from 3.3 V. IC Role / Device Role / Timing Role: First-stage AC-coupled gain block with biasing network; uses rail-to-rail output to maximize headroom. Use Value: 42 nV/√Hz input noise ensures SNR >85 dB for 20–20 kHz audio; no crossover distortion avoids harmonic artifacts. | Use Scenario: 4-channel 4–20 mA loop receiver in PLC I/O modules with local signal conditioning. IC Role / Device Role / Timing Role: Transimpedance and level-shifting amplifier per channel before isolation and digitization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324DR | Lower 1 MHz GBW, 0.6 V/μs slew rate, higher 1.25 mA total ICC, but wider –40°C to 125°C temp range. | Preferred for cost-sensitive industrial controls where bandwidth <100 kHz suffices and extended temperature is mandatory. | Select LMV324DR when thermal robustness outweighs speed; avoid if >200 kHz small-signal response is required. |
| TLV2464CDR | Higher 6.4 MHz GBW, 1.6 V/μs slew rate, 1.2 mA total ICC, rail-to-rail I/O, and 1.8 V min supply - broader voltage range. | Better suited for ultra-low-voltage designs (e.g., coin-cell powered devices) requiring same-speed performance below 2.5 V. | Choose TLV2464CDR when operating below 2.5 V or needing tighter offset (0.6 mV typ) - verify layout for higher PSRR sensitivity. |
Compared with LMV324DR and TLV2464CDR, LMV824DE4 offers optimal balance of speed (5.5 MHz), low power (1 mA), and rail-to-rail output at 2.5–5.5 V - making it the preferred choice for portable, battery-constrained systems requiring clean, wideband signal conditioning without over-spec'ing supply voltage range.

FAQ
What is the operating temperature range for LMV824DE4?
The LMV824DE4 is characterized for operation from –40°C to +85°C. This range is specified in the official Texas Instruments SLOS434I datasheet and applies to all electrical parameters unless otherwise noted. The LMV824DE4 variant does not support the extended –40°C to +125°C range offered by the LMV824I-series parts. Designers should ensure ambient and junction temperatures remain within this window during full-load operation.
Is LMV824DE4 pin-compatible with other LMV824 variants?
Yes, LMV824DE4 is pin-compatible with all SOIC-14 packaged LMV824 variants including LMV824D, LMV824DR, and LMV824ID. All share identical pinout, footprint, and terminal functions per TI's D-package drawing. However, note that LMV824DE4 and LMV824D are both rated for –40°C to 85°C, while LMV824ID supports –40°C to 125°C - thermal derating must be verified separately.
Does LMV824DE4 support true rail-to-rail input?
No, LMV824DE4 does not feature rail-to-rail input. Its common-mode input voltage range extends from –0.2 V to 4.2 V at VCC+ = 5 V - meaning it includes ground but does not reach the positive rail. The input stage is CMOS-based and optimized for single-supply use with ground-referenced signals, but cannot accept inputs equal to VCC+. For full rail-to-rail input, consider alternatives like TLV2464.
What is the maximum capacitive load LMV824DE4 can drive stably?
LMV824DE4 maintains stability with capacitive loads up to 22 pF when configured for 40-dB closed-loop gain, as confirmed in the datasheet's phase margin characterization (Figure 17–21). Driving larger capacitive loads (e.g., >100 pF) requires external isolation resistance (e.g., 10–100 Ω in series with the output) or gain adjustment to preserve ≥60° phase margin and prevent peaking or oscillation.
Why is LMV824DE4 marked "Not Recommended for New Designs"?
LMV824DE4 is marked "Not Recommended for New Designs" per Texas Instruments' 2016 packaging addendum due to obsolescence status - all orderable variants (including LMV824DE4) are listed as OBSOLETE. TI recommends migrating to newer alternatives such as TLV9064 or OPA4991 for enhanced specs, active support, and guaranteed long-term availability. LMV824DE4 remains available through authorized distributors for legacy repair and continuity, but no new design-in is advised.
