Product details
Overview
LMV824QPWRQ1 from Texas Instruments is a quad-channel, rail-to-rail output operational amplifier designed for automotive-grade signal conditioning in low-voltage systems. It operates from 2.5 V to 5.5 V, delivers 5.5 MHz gain bandwidth and 1.9 V/µs slew rate at 5 V, and supports –40°C to 125°C ambient operation with no crossover distortion - used in engine control sensor interfaces and body electronics analog front-ends.
For engineers reviewing the LMV824QPWRQ1 datasheet, LMV824QPWRQ1 pinout, LMV824QPWRQ1 application, or LMV824QPWRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, 1 mA typical supply current across all four amplifiers, rail-to-rail output swing within 10 mV of rails (at 2 kΩ load), and TSSOP-14 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The LMV824QPWRQ1 implements a CMOS input stage with rail-to-rail output stage, enabling full-swing operation in single-supply configurations down to 2.5 V. Its internal architecture supports high common-mode rejection (72 dB min at 5 V) and supply voltage rejection (75 dB min positive SVR), critical for noisy automotive power domains.
It features amplifier-to-amplifier isolation of 135 dB at 1 kHz, minimizing crosstalk in multi-channel sensing applications such as multi-axis position feedback or redundant sensor monitoring. The device maintains stable phase margin (64.2° typ) with 600 Ω–100 kΩ loads and up to 200 pF capacitive loading, supporting direct driving of ADC inputs or long trace routing without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - enables direct interface with 3.3 V and 5 V microcontrollers and sensors without level-shifting. |
| Gain Bandwidth Product | 5.5 MHz typ at 5 V - supports closed-loop bandwidth >1 MHz for fast-response sensor amplification (e.g., knock detection). |
| Slew Rate | 1.9 V/µs typ at 5 V - ensures faithful reproduction of 100 kHz signals with ≤0.1% distortion in active filter stages. |
| Input Offset Voltage | 6 mV max over –40°C to 125°C - maintains <±10 mV error in precision current-sense amplification at full temperature range. |
| Rail-to-Rail Output Swing | Within 10 mV of VCC+ and GND at 2 kΩ load - maximizes dynamic range for 12-bit ADC interfacing in battery-monitoring circuits. |
| Quiescent Current | 1.3 mA max (all four amps) at 125°C - enables always-on sensor nodes with sub-2 µA standby when combined with enable logic. |
| Common-Mode Rejection | 70 dB min over full temp range - rejects coupled noise from shared ground paths in motor driver feedback loops. |
Pinout & Package
TSSOP-14 (PW) package: 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant green finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives low-impedance loads (≤600 Ω) directly; requires local 100 nF bypass to GND. |
| 2 | IN1– | Inverting input of Amp1 - high-impedance node; layout symmetry critical for CMRR preservation. |
| 3 | IN1+ | Non-inverting input of Amp1 - referenced to system ground or bias network; accepts input common-mode down to –0.3 V. |
| 4 | GND / VCC– | Power return and negative supply rail - must be low-inductance plane; shared with other analog sections only if isolated via ferrite bead. |
| 5 | IN2+ | Non-inverting input of Amp2 - independent channel; usable for differential pair with IN2– (Pin 6). |
| 6 | IN2– | Inverting input of Amp2 - matches IN1– electrical characteristics; supports unity-gain stable configuration. |
| 7 | OUT2 | Amplifier 2 output - electrically isolated from OUT1; suitable for separate feedback networks. |
| 8 | VCC+ | Positive supply rail - requires dedicated 10 µF + 100 nF decoupling at package edge; not shared with digital VCC. |
| 9 | OUT3 | Amplifier 3 output - identical drive capability to OUT1/OUT2; routed separately to avoid coupling into sensitive nodes. |
| 10 | IN3– | Inverting input of Amp3 - pin-compatible with IN1–/IN2–; supports matched resistor networks for gain-setting. |
| 11 | IN3+ | Non-inverting input of Amp3 - accepts same input voltage range as IN1+/IN2+ (–0.3 V to VCC+ + 0.3 V). |
| 12 | IN4+ | Non-inverting input of Amp4 - enables simultaneous 4-channel signal conditioning without inter-channel timing skew. |
| 13 | IN4– | Inverting input of Amp4 - fully characterized for AC/DC performance matching other channels. |
| 14 | OUT4 | Amplifier 4 output - verified for 135 dB isolation from OUT1–OUT3; validated for use in dual-redundant safety-critical paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824QDRQ1 | SOIC-14 package (3.9 mm × 4.9 mm); higher thermal resistance (97°C/W vs. 113°C/W); identical electrical specs. | Preferred for through-hole prototyping or legacy board designs requiring SOIC footprint. | Select when board assembly uses wave soldering or requires larger pad geometry for manual rework. |
| TSV914IQDT | Higher GBW (8 MHz), lower noise (14 nV/√Hz), but only qualified to AEC-Q100 Grade 2 (–40°C to 105°C); 1.2 mA supply current. | Suitable for ADAS camera ISPs needing wider bandwidth, but not for under-hood engine control. | Choose for vision-processing front-ends where extended temperature range is not required and bandwidth is prioritized. |
Compared with LMV824QDRQ1 and TSV914IQDT, the LMV824QPWRQ1 offers optimal balance of automotive temperature compliance, compact TSSOP packaging, and proven stability in noisy powertrain environments - making it the default choice for new AEC-Q100 Grade 1 designs requiring four matched amplifiers.

FAQ
What is the maximum operating temperature range for the LMV824QPWRQ1?
The LMV824QPWRQ1 is qualified for continuous operation from –40°C to +125°C ambient temperature per AEC-Q100 Grade 1 requirements. This rating is validated across all electrical parameters including input offset voltage, supply current, and gain bandwidth - ensuring reliable performance in engine compartment and transmission control applications where junction temperatures may exceed 140°C under worst-case power dissipation.
Does the LMV824QPWRQ1 support single-supply operation?
Yes, the LMV824QPWRQ1 supports true single-supply operation from 2.5 V to 5.5 V. Its input common-mode range extends from –0.3 V below GND to VCC+ + 0.3 V, and its rail-to-rail output swings within 10 mV of both supply rails at 2 kΩ load. This enables direct interfacing with 3.3 V microcontrollers and sensors without level-shifting circuitry - a key feature confirmed in the 2.5-V, 2.7-V, and 5-V electrical characteristics tables of the LMV824QPWRQ1 datasheet.
What is the quiescent current consumption of the LMV824QPWRQ1 at 125°C?
The LMV824QPWRQ1 draws a maximum of 1.5 mA total supply current across all four amplifiers at 125°C and 5 V supply, as specified in the 5-V Electrical Characteristics table. At 25°C and 5 V, typical consumption is 1.0 mA. This low-power profile enables use in always-on automotive subsystems such as intrusion detection or battery monitoring, where sustained operation at elevated temperature must not compromise system-level power budgets.
Is the LMV824QPWRQ1 pin-compatible with other devices in the LMV82x-Q1 family?
The LMV824QPWRQ1 shares identical pinout and functionality with the LMV824QDRQ1 (SOIC-14), as both implement the same TSSOP/SOIC-14 quad op-amp topology shown in the "LMV824…D OR PW PACKAGE" diagram. However, it is not pin-compatible with LMV822-Q1 (8-pin DGK) or LMV821-Q1 (5-pin DBV). Pin mapping is strictly defined in the top-view package drawings - confirming that Pins 1–14 serve identical amplifier channel and power functions across D and PW packages.
What packaging and environmental compliance does the LMV824QPWRQ1 meet?
The LMV824QPWRQ1 is supplied in a RoHS-compliant, green (Pb-free, Sb/Br-free) TSSOP-14 (PW) 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 reliability standards and is manufactured in TI's ISO/TS 16949-certified facilities - ensuring traceability, lot control, and automotive-grade process consistency required for safety-critical vehicle systems.
