Product details
Overview
LMV324QPWRG4Q1 from Texas Instruments is a quad-channel, automotive-grade operational amplifier with rail-to-rail output swing, 1-MHz unity-gain bandwidth, 1-V/µs slew rate, and 410-µA typical supply current per amplifier at 5 V. It operates from 2.7 V to 5.5 V and features ground-sensing input common-mode range, making it suitable for low-voltage sensor signal conditioning in engine control units and body electronics.
For engineers reviewing the LMV324QPWRG4Q1 datasheet, LMV324QPWRG4Q1 pinout, LMV324QPWRG4Q1 application, or LMV324QPWRG4Q1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (−40°C to +125°C), TSSOP-14 package thermal performance (θJA = 113°C/W), rail-to-rail output capability under 2-kΩ load, and absence of crossover distortion in single-supply configurations.
Technical Context
The LMV324QPWRG4Q1 implements a CMOS-input, rail-to-rail output architecture optimized for low-voltage operation. Its input stage supports common-mode voltage down to ground (−0.2 V at 5 V), enabling direct interfacing with resistive sensors and DAC outputs without level-shifting circuitry.
Each of the four amplifiers delivers 1-MHz unity-gain bandwidth and 60° phase margin into 2-kΩ/200-pF loads, ensuring stable operation in closed-loop configurations such as active filters and transimpedance amplifiers across the full automotive temperature range.
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 |
|---|---|---|---|
| LMV324QDRQ1 | SOIC-14 package (θJA = 86°C/W); same electrical specs and AEC-Q100 Grade 1 rating | Better thermal dissipation in high-ambient environments; larger PCB footprint | Select when board layout allows SOIC and thermal management requires lower junction rise |

FAQ
What is the operating temperature range for LMV324QPWRG4Q1?
The LMV324QPWRG4Q1 is qualified per AEC-Q100 Grade 1, with a specified operating free-air temperature range of −40°C to +125°C. This rating is validated across all electrical parameters in the datasheet's "electrical characteristics at specified free-air temperature range" tables and applies to the TSSOP-14 (PW) package variant shipped as LMV324QPWRG4Q1.
Does LMV324QPWRG4Q1 support true rail-to-rail input operation?
LMV324QPWRG4Q1 does not provide rail-to-rail input common-mode range. Its input common-mode voltage range extends from −0.2 V to VCC + 0.2 V (at 5 V supply), which includes ground but does not reach VCC. However, the output is rail-to-rail: it swings within 100 mV of VCC and 180 mV of GND under 10-kΩ load conditions, as confirmed in the "electrical characteristics" tables for LMV324-Q1.
What is the maximum capacitive load LMV324QPWRG4Q1 can drive stably?
LMV324QPWRG4Q1 maintains stability with up to 500 pF capacitive load when driving a 2-kΩ resistive load (Figure 3), exhibiting ≤25% overshoot. For loads exceeding 500 pF, external compensation (e.g., series resistor at output) is recommended. The device's phase margin remains ≥60° under these conditions, per typical characterization data in Figures 1–4 of the SLOS415E datasheet.
Is LMV324QPWRG4Q1 pin-compatible with standard LM324 variants?
No, LMV324QPWRG4Q1 is not pin-compatible with legacy LM324 variants. While both are quad op-amps in 14-pin packages, LMV324QPWRG4Q1 uses the industry-standard TSSOP-14 pinout (identical to LMV324IPWRQ1), whereas LM324 typically uses DIP-14 or SOIC-14 with different pin assignments (e.g., VCC on pin 4, GND on pin 11). Direct replacement requires PCB redesign.
What packaging and environmental compliance does LMV324QPWRG4Q1 meet?
LMV324QPWRG4Q1 is supplied in a green (RoHS-compliant, Pb-free, no Sb/Br) TSSOP-14 package with CU NIPDAU lead finish and JEDEC MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH). It meets AEC-Q100 Grade 1 stress testing requirements and is rated for automotive under-hood and cabin applications per TI's qualified versions documentation.
