Product details
Overview
LMV824D from Texas Instruments is a quad, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 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, operating across –40°C to 85°C. It serves signal conditioning and sensor interface roles in portable instrumentation and battery-powered analog front-ends.
For engineers reviewing the LMV824D datasheet, LMV824D pinout, LMV824D application, or LMV824D equivalent, key selection criteria include rail-to-rail output swing (4.85 V at 5 V supply, RL = 2 kΩ), input common-mode range extending to ground, low input offset voltage (1 mV typ), and SOIC-14 package compatibility with space-constrained PCB layouts.
Technical Context
The LMV824D implements a CMOS input stage with rail-to-rail output stage, enabling full-swing operation from single-supply rails as low as 2.5 V. Its architecture supports unity-gain stable operation with capacitive loads up to 22 pF while maintaining ≥64.2° phase margin at 5 V.
It features no crossover distortion, achieves 135 dB amplifier-to-amplifier isolation, and maintains consistent performance across its specified temperature range without requiring external compensation components in standard configurations.

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 package; differs only in reel packaging (2500/reel vs. tube of 90 for LMV824D). | No functional difference; suitable for automated assembly where tape-and-reel is required. | Select LMV824DR for SMT production; LMV824D remains valid for prototyping or low-volume hand-soldered builds. |
| TLV2464CD | Higher supply current (1.4 mA typ), lower GBW (6.4 MHz), wider VCC range (2.7–6 V); pin-compatible but not drop-in due to different input bias current (1 pA vs. 30 nA). | Better for ultra-low-noise or higher-precision applications where input bias current matters less than noise floor. | Choose TLV2464CD only when sub-pA input bias is required; otherwise LMV824D offers better cost/performance for general-purpose use. |
Compared with LMV824DR, LMV824D offers identical performance in tube packaging for manual assembly, while TLV2464CD trades higher precision for increased power and cost-making LMV824D optimal for cost-sensitive, low-power industrial and portable designs.

FAQ
What is the operating temperature range for LMV824D?
The LMV824D is characterized for operation from –40°C to +85°C. This range is validated per the datasheet's recommended operating conditions and applies to all electrical specifications unless otherwise noted. The LMV824D is not rated for extended temperature operation (e.g., –40°C to +125°C), which is reserved for the LMV824ID variant. Thermal derating is not required within this range.
Does LMV824D support true rail-to-rail input?
No, LMV824D does not support rail-to-rail input. Its input common-mode voltage range extends to VCC– (GND) but only up to VCC+ – 0.3 V at 25°C. It accepts signals from ground but cannot reliably process inputs at the positive rail. However, its rail-to-rail output stage delivers swing within 100 mV of both supply rails under typical loads.
What is the maximum capacitive load LMV824D can drive while remaining stable?
The LMV824D is unity-gain stable with capacitive loads up to 22 pF when configured with a 40-dB closed-loop DC gain and tested per the datasheet methodology. Driving larger capacitive loads (e.g., >100 pF) may cause peaking or oscillation unless an isolation resistor (e.g., 10–50 Ω) is added in series with the output. Stability is confirmed at 5 V supply and 25°C ambient.
Is LMV824D pin-compatible with LMV822D or LMV821DBVR?
No, LMV824D is not pin-compatible with LMV822D or LMV821DBVR. LMV824D uses a 14-pin SOIC package with dedicated pins for four independent amplifiers. LMV822D is an 8-pin SOIC dual op-amp, and LMV821DBVR is a 5-pin SOT-23 single op-amp. Their pinouts, channel counts, and package footprints differ fundamentally-PCB layout changes are required for substitution.
What is the typical input offset voltage drift over temperature for LMV824D?
The LMV824D has an average input offset voltage temperature coefficient (αVIO) of 1 μV/°C, as specified in the 2.7-V and 5-V electrical characteristics tables. This value is measured at 25°C and reflects typical drift behavior across the –40°C to +85°C range. Measured VIO remains ≤4 mV across that full range, consistent with the 1 μV/°C drift model.
