Product details
Overview
LMV824IDE4 from Texas Instruments is a quad, low-voltage, rail-to-rail output operational amplifier optimized for 2.5 V to 5.5 V single-supply operation. 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 instrumentation and sensor interfaces.
For engineers reviewing the LMV824IDE4 datasheet, LMV824IDE4 pinout, LMV824IDE4 application, or LMV824IDE4 equivalent, this page provides verified technical context, SOIC-14 package mapping, real-world use cases in battery-powered analog front-ends, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The LMV824IDE4 integrates four independent high-fidelity amplifiers sharing a common 2.5–5.5 V supply. Each channel features rail-to-rail output swing (within 17 mV of rails at 5 V, RL = 600 Ω), no crossover distortion, and input common-mode range extending 0.3 V below ground - supporting true single-supply sensor biasing and level-shifting.
Its 5.5 MHz GBW and 1.9 V/μs slew rate support stable closed-loop operation up to unity gain with capacitive loads ≤22 pF, while amplifier-to-amplifier isolation exceeds 135 dB at 1 kHz - critical for multi-channel data acquisition where crosstalk must be minimized.
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 without level shifters |
| Gain Bandwidth Product | 5.5 MHz typ at 5 V - supports stable unity-gain buffers and 2nd-order active filters up to ~500 kHz |
| Slew Rate | 1.9 V/μs typ at 5 V - ensures <1% THD for 100-kHz, 2-Vpp signals in voltage-follower configuration |
| Input Offset Voltage | 1 mV typ, 4 mV max (–40°C to 85°C) - maintains <100 μV error in 100× gain sensor amplification |
| Output Swing | Within 17 mV of rails (high), 100 mV of rails (low) at 5 V, RL = 2 kΩ - maximizes dynamic range in single-supply ADC drivers |
| Quiescent Current | 1 mA typ (all four amps at 5 V) - allows 4-channel amplification in sub-10-mA system power budgets |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824DR | Same SOIC-14 package and electrical specs, but rated for –40°C to 85°C only; 1 mA ICC at 5 V matches LMV824IDE4 | Not suitable for under-hood or extended-temperature industrial deployments requiring 125°C operation | Select LMV824DR only when ambient temperature remains ≤85°C and cost sensitivity outweighs extended temp qualification |
| TLV2464IDR | Higher 6.4 MHz GBW and 1.6 V/μs slew rate; 1.25 mA ICC at 5 V; wider input common-mode range (to VCC+) | Better suited for higher-speed multi-pole filter designs but exhibits higher noise (28 nV/√Hz vs. 42 nV/√Hz) | Choose TLV2464IDR when >5.5 MHz bandwidth is required and thermal margin permits higher ICC; verify noise impact in low-level sensor paths |
Compared with LMV824DR, LMV824IDE4 adds guaranteed 125°C operation without sacrificing speed or power; versus TLV2464IDR, it trades 0.9 MHz bandwidth for lower noise and proven stability with 22-pF capacitive loads - making it preferable for precision, temperature-robust, multi-channel analog front-ends.

FAQ
What is the operating temperature range for LMV824IDE4?
The LMV824IDE4 is characterized for operation from –40°C to +125°C. This extended temperature range qualifies it for under-hood automotive applications, industrial control cabinets, and outdoor environmental monitoring systems where ambient temperatures exceed standard commercial-grade limits. All key parameters - including input offset voltage, gain bandwidth, and output swing - are guaranteed across this full range per the TI SLOS434I datasheet.
Does LMV824IDE4 support true single-supply operation with inputs referenced to ground?
Yes, LMV824IDE4 supports true single-supply operation with inputs referenced to ground. Its input common-mode voltage range extends to –0.3 V (below GND) and up to VCC–0.2 V, allowing direct connection of grounded-sensor outputs such as thermocouples, strain gauges, and bridge transducers without external level-shifting circuitry. This capability is confirmed in the "Common-mode input voltage range" specification table for both 2.7 V and 5 V supply conditions.
What is the maximum capacitive load LMV824IDE4 can drive while maintaining stability?
LMV824IDE4 maintains phase margin ≥64° and gain margin ≥8.7 dB when driving capacitive loads up to 22 pF with a 40-dB closed-loop gain configuration, as verified in Figure 17 of the SLOS434I datasheet. For loads exceeding 22 pF, external series resistance (≥100 Ω) at the output is recommended to preserve stability. The device is not unity-gain stable with heavy capacitive loading without compensation.
How does LMV824IDE4 compare to LMV824D in terms of performance and qualification?
LMV824IDE4 and LMV824D share identical electrical specifications (GBW, SR, VIO, ICC, etc.) and SOIC-14 packaging, but differ in temperature qualification: LMV824IDE4 is rated for –40°C to +125°C operation, whereas LMV824D is limited to –40°C to +85°C. Both parts use the same silicon die; the "I" suffix denotes extended temperature screening and testing per TI's automotive/industrial qualification standards.
Is LMV824IDE4 pin-compatible with other quad op-amps in SOIC-14 packages?
LMV824IDE4 follows the industry-standard SOIC-14 pinout for quad op-amps (pin 1 = Ch1 out, pin 2 = Ch1 −, pin 3 = Ch1 +, ..., pin 14 = Ch4 out), matching TI's own TLV2464, OPA4340, and generic quad op-amp footprints. However, absolute pin compatibility requires verification of input/output polarity and power pin locations - LMV824IDE4 places VCC+ on pin 8 and GND on pin 7, consistent with most TI quad op-amps but differing from some competitors' assignments.
