Product details
Overview
LMV824QDRQ1 from Texas Instruments is a quad, rail-to-rail output operational amplifier qualified for automotive applications and operating from –40°C to 125°C. 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 automotive sensor interfaces and body control modules.
For engineers reviewing the LMV824QDRQ1 datasheet, LMV824QDRQ1 pinout, LMV824QDRQ1 application, or LMV824QDRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, rail-to-rail output swing down to 100 mV from rails (at 2 kΩ load), low input offset voltage (≤6 mV over temperature), and SOIC-14 packaging compatible with standard automotive PCB assembly processes.
Technical Context
The LMV824QDRQ1 integrates four independent amplifiers on a single die with fully rail-to-rail output stage architecture, supporting single-supply operation from 2.5 V to 5.5 V. Its input common-mode range extends from VCC– to VCC+, includes ground, and exhibits no crossover distortion - critical for accurate low-voltage signal acquisition in automotive microcontroller analog front-ends.
Designed for stability with capacitive loads up to 22 pF and resistive loads as low as 600 Ω, the device maintains ≥64.2° phase margin at 5 V with 600 Ω load, and achieves 135 dB amplifier-to-amplifier isolation - enabling multi-channel sensing without crosstalk in shared power domains.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824QPWRQ1 | TSSOP-14 package (4.4 mm × 5 mm); 113°C/W θJA vs. SOIC's 97°C/W; identical electrical specs. | Better suited for high-density PCB layouts where SOIC footprint is prohibitive; requires tighter reflow profile control. | Select when board space is constrained and thermal management via copper pour is feasible. |
| TSV914IQDT | Higher GBW (8 MHz), lower input offset (1.5 mV max), but higher ICC (1.5 mA typ); not AEC-Q100 qualified. | Applicable in non-safety-critical industrial or consumer designs needing higher precision or speed. | Choose only for non-automotive use cases where AEC-Q100 compliance is not required. |
Compared with LMV824QPWRQ1, LMV824QDRQ1 offers superior thermal performance in SOIC packaging and drop-in compatibility with legacy automotive designs; versus TSV914IQDT, it trades bandwidth and offset for guaranteed automotive qualification and lower quiescent power - making it the sole option for ASIL-compliant systems requiring quad op-amp functionality.

FAQ
What is the maximum operating temperature range for LMV824QDRQ1?
The LMV824QDRQ1 is qualified for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and output swing - ensuring reliable performance in under-hood and cabin-mounted automotive applications where thermal cycling is severe.
Does LMV824QDRQ1 support true rail-to-rail input operation?
LMV824QDRQ1 features rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range extends from VCC– (ground in single-supply) to VCC+, meaning it accepts signals at ground potential and up to the positive rail - a key advantage over traditional op-amps that exclude the rails. However, differential input voltage must remain within ±VCC, and inputs should not exceed supply rails.
Can LMV824QDRQ1 drive a 600 Ω load while maintaining rail-to-rail output swing?
Yes - at 5 V supply, LMV824QDRQ1 delivers output swing within 170 mV of VCC+ and 250 mV of GND when sourcing/sinking into a 600 Ω load, as specified in the 5-V Electrical Characteristics table. This capability enables direct interfacing with legacy analog inputs or low-impedance transducers without external buffer stages, reducing component count in automotive signal chains.
Is LMV824QDRQ1 pin-compatible with other LMV82x-Q1 variants?
No - LMV824QDRQ1 (SOIC-14) is not pin-compatible with LMV822QDGKRQ1 (MSOP-8) or LMV821QDBVRQ1 (SOT-23-5). While all share identical amplifier core characteristics, their pin counts and layouts differ fundamentally. The LMV824QDRQ1 pinout is unique to the quad SOIC package and matches only LMV824QPWRQ1 (TSSOP-14) in functional pin assignment, though physical layout differs.
What is the typical supply current consumption of LMV824QDRQ1 at 3.3 V operation?
At 3.3 V supply and 25°C, LMV824QDRQ1 draws approximately 0.85 mA typical total supply current for all four amplifiers - interpolated from the 2.7 V (0.72 mA typ) and 5 V (1.0 mA typ) data points in the Electrical Characteristics tables. This value remains stable across the –40°C to 125°C range, with maximum ICC ≤1.5 mA, supporting low-power always-on vehicle subsystems.
