Product details
Overview
LMV324IPWRG4Q1 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 at 2.7 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 LMV324IPWRG4Q1 datasheet, LMV324IPWRG4Q1 pinout, LMV324IPWRG4Q1 application, or LMV324IPWRG4Q1 equivalent, key selection criteria include its AEC-Q100 qualification, TSSOP-14 package thermal performance (θJA = 113°C/W), rail-to-rail output capability under light load (±100 mV from rails at 10 kΩ), and guaranteed operation over −40°C to 125°C.
Technical Context
The LMV324IPWRG4Q1 implements a CMOS-input, rail-to-rail output op-amp architecture optimized for single-supply automotive systems. Its input stage supports common-mode voltages down to ground (−0.2 V at 5 V supply), enabling direct interfacing with resistive sensors and DAC outputs without level-shifting.
Each of the four amplifiers delivers 1-MHz gain-bandwidth product and 60° phase margin into 100-pF capacitive loads, with internal compensation ensuring stability across temperature and supply voltage variations from 2.7 V to 5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - Enables direct interface with 3.3 V and 5 V automotive microcontrollers and sensors. |
| Unity-Gain Bandwidth | 1 MHz - Supports audio pre-amplification, battery monitoring, and medium-speed sensor signal conditioning. |
| Slew Rate | 1 V/µs - Sufficient for 100-kHz full-power sine wave output at 1-V peak amplitude. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324QPWRQ1 | Same silicon, identical electrical specs, but RoHS-compliant finish without Sb/Br exemption (Green vs CU NIPDAU). | No functional difference; both qualified for −40°C to +125°C automotive use. | Select LMV324QPWRQ1 if full Green (RoHS + no Sb/Br) compliance is mandated by OEM specification. |
| TSV914IQDT | Higher GBW (8 MHz), lower input offset (1.5 mV max), but higher supply current (820 µA) and not AEC-Q100 qualified. | Not suitable for safety-critical automotive applications requiring qualification evidence. | Choose TSV914IQDT only for non-automotive industrial designs needing higher speed and precision at cost of qualification and power. |
Compared with LMV324QPWRQ1, LMV324IPWRG4Q1 offers identical performance with TI's legacy CU NIPDAU finish; versus TSV914IQDT, it trades bandwidth and offset for guaranteed automotive qualification and 47% lower quiescent current-critical for always-on modules.

FAQ
What is the operating temperature range for LMV324IPWRG4Q1?
The LMV324IPWRG4Q1 is qualified for operation from −40°C to +125°C, meeting AEC-Q100 Grade 1 requirements for automotive under-hood and powertrain applications. This range is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and output swing, with no derating required at temperature extremes.
Does LMV324IPWRG4Q1 support rail-to-rail input?
No, LMV324IPWRG4Q1 does not support rail-to-rail input. Its common-mode input voltage range extends to ground (−0.2 V at 5 V supply) but stops 1.3 V below VCC. However, it does provide true rail-to-rail output swing-within 100 mV of both VCC and GND under 10-kΩ load-making it ideal for single-supply sensor interfaces where input referencing is controlled.
What is the maximum capacitive load LMV324IPWRG4Q1 can drive stably?
LMV324IPWRG4Q1 maintains ≥60° phase margin and stable operation with up to 100 pF capacitive load when driving a 2-kΩ resistive load, as verified in Figure 3 of the datasheet. For loads exceeding 100 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to prevent peaking or oscillation in high-impedance sensor buffering applications.
Is LMV324IPWRG4Q1 pin-compatible with standard LM324 variants?
No, LMV324IPWRG4Q1 is not pin-compatible with legacy LM324 variants. While both are quad op-amps in 14-pin packages, LMV324IPWRG4Q1 uses the industry-standard TSSOP-14 pinout (identical to LMV324IPWRQ1), whereas LM324 uses DIP/SOIC-14 with different pin assignments-for example, LM324 places GND on pin 4 and VCC on pin 8, while LMV324IPWRG4Q1 places GND on pin 4 and VCC on pin 14.
What packaging and environmental compliance does LMV324IPWRG4Q1 meet?
LMV324IPWRG4Q1 is supplied in a green (RoHS & 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 complies with AEC-Q100 Grade 1 stress testing and TI's corporate environmental policy, with no halogenated flame retardants and lead content below 100 ppm in homogeneous materials.
