Product details
Overview
TLV9044QPWRQ1 from Texas Instruments is a quad-channel AEC-Q100 Grade 1 automotive operational amplifier optimized for ultra-low-voltage, micro-power sensing and signal conditioning in battery-constrained systems. It operates from 1.2V to 5.5V supply, draws only 10µA per channel, delivers rail-to-rail input/output swing, and features 350kHz gain-bandwidth product - enabling precision analog front-ends in HEV/EV on-board chargers and thermal management modules.
For engineers reviewing the TLV9044QPWRQ1 datasheet, TLV9044QPWRQ1 pinout, TLV9044QPWRQ1 application, or TLV9044QPWRQ1 equivalent, key selection criteria include its 1.2V minimum supply operation, ±0.6mV typical input offset voltage, 1pA typical input bias current, integrated RFI/EMI filtering, and robust 100pF capacitive load drive - all validated across –40°C to +125°C.
Technical Context
The TLV9044QPWRQ1 employs a complementary input stage (N- and P-channel differential pairs) to achieve true rail-to-rail input operation down to 1.2V supply, with the P-channel pair active up to (V+) – 0.7V - significantly extending high-linearity input range versus legacy low-voltage op amps. Its unity-gain stable architecture supports direct connection to SAR ADCs without external compensation.
Internal EMI/RFI filtering on input pins, no-phase-reversal behavior under overdrive, and 65° phase margin at 10pF load ensure robust performance in noisy automotive environments. The class AB output stage drives ≥2kΩ resistive loads and sustains 40mA short-circuit current at 5.5V, supporting fault-tolerant sensor interface designs.
Key Specifications

|---|---|
| Supply Voltage Range | 1.2V to 5.5V - enables direct operation from single-cell LiFePO₄ or dual-cell alkaline batteries without regulation. |
| Quiescent Current / Channel | 10µA typical - reduces system standby power by >50% vs comparable 350kHz op amps. |
| Input Offset Voltage | ±0.6mV typical - supports <0.1% accuracy in 12-bit sensor signal chains without trimming. |
| Gain-Bandwidth Product | 350kHz - sufficient for anti-aliasing filters and DC–10kHz sensor conditioning with stable unity-gain response. |
| Input Bias Current | 1pA typical - preserves signal integrity in high-impedance pH, thermopile, or piezoelectric sensor interfaces. |
| Rail-to-Rail I/O | Full swing from V– to V+ - maximizes dynamic range in 1.2V–3.3V MCU-based systems, improving ADC utilization. |

Pinout & Package
TSSOP-14 (PW) package: 5.00mm × 6.40mm body, 0.65mm pitch, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1, OUT2, OUT3, OUT4 | Amplifier outputs - each independently drives loads up to 100pF with 0.2V/μs slew rate and no phase reversal. |
| 2, 6, 9, 13 | IN1–, IN2–, IN3–, IN4– | Inverting inputs - high-impedance (100GΩ || 0.5pF), EMI-filtered, compatible with high-Z sensors. |
| 3, 5, 10, 12 | IN1+, IN2+, IN3+, IN4+ | Noninverting inputs - rail-to-rail common-mode range (V– to V+), enabling single-supply level-shifting. |
| 4 | V+ | Positive supply - accepts 1.2V–5.5V; requires local 0.01µF ceramic bypass capacitor. |
| 11 | V– | Negative supply or ground - supports single-supply (V– = GND) or split-supply (V– = –VS/2) configurations. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - suitable for engine bay and powertrain control units. |
| Integrated RFI/EMI filtering | On-chip input filtering rejects 1GHz cellular/WiFi noise - eliminates need for external ferrite beads or RC networks. |
| No phase reversal on overdrive | Output remains monotonic when input exceeds rails - prevents latch-up or false triggering in safety-critical comparators. |
| Low 0.1Hz–10Hz noise | 6.5µVP-P - enables stable DC-coupled amplification of slow thermal or pressure signals without 1/f noise corruption. |
| High channel separation | –5.6µV/V crosstalk at 10kHz - maintains signal integrity in multi-sensor monitoring (e.g., cabin temp + seat occupancy). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9004QPWRQ1 | Lower GBW (1MHz), higher IQ (60µA/ch), same 1.2V–5.5V range and AEC-Q100 Grade 1 rating. | Better for higher-speed sensor interfaces (e.g., ultrasonic parking assist); less suitable for ultra-low-power always-on nodes. | Choose TLV9004QPWRQ1 when bandwidth >350kHz is required and 6× higher quiescent current is acceptable. |
| LMV324QDRQ1 | Higher IQ (120µA/ch), wider offset range (±3mV), no 1.2V operation - min supply 2.7V; AEC-Q100 Grade 1. | Compatible with legacy 3.3V/5V domains but cannot operate during cold-crank or low-battery conditions. | Choose LMV324QDRQ1 only if existing 2.7V+ supply infrastructure exists and micro-power operation is not required. |
Compared with TLV9044QPWRQ1, TLV9004QPWRQ1 trades 6× higher power for 3× more bandwidth, while LMV324QDRQ1 lacks sub-2.7V capability entirely - making TLV9044QPWRQ1 uniquely suited for next-generation 12V battery–direct, always-on automotive subsystems.

FAQ
What is the minimum supply voltage for reliable operation of the TLV9044QPWRQ1?
The TLV9044QPWRQ1 is fully specified to operate from 1.2V to 5.5V supply voltage. At 1.2V, it maintains rail-to-rail input/output swing, 350kHz gain-bandwidth product, and 10µA per channel quiescent current - enabling direct interface with single-cell LiFePO₄ batteries or energy-harvesting sources. Performance parameters such as offset voltage and CMRR are guaranteed across this full range per AEC-Q100 Grade 1 testing.
Does the TLV9044QPWRQ1 support single-supply operation?
Yes, the TLV9044QPWRQ1 supports true single-supply operation with V– connected to ground. Its rail-to-rail input common-mode range extends from V– to V+, and output swings within 1mV of both rails at 5.5V supply (and <8mV at 1.2V). This allows direct interfacing with 1.2V–3.3V MCUs and ADCs without level-shifting circuitry - critical for compact, low-cost automotive sensor nodes.
How does the TLV9044QPWRQ1 handle electromagnetic interference in automotive environments?
The TLV9044QPWRQ1 integrates on-die RFI and EMI filtering on all input pins, achieving 70dB rejection at 1GHz. This is validated per AEC-Q100 test methods and eliminates the need for external RC filters or ferrite beads in applications like car access systems exposed to Bluetooth, WiFi, or UWB emissions. Measured channel separation of –5.6µV/V at 10kHz further isolates adjacent amplifier channels from coupled noise.
Is the TLV9044QPWRQ1 pin-compatible with other devices in the TLV904x-Q1 family?
No - the TLV9044QPWRQ1 (quad, TSSOP-14) has a distinct pinout from TLV9041-Q1 (single, SOT-23-5/SC70-5) and TLV9042-Q1 (dual, SOIC-8/VSSOP-8/TSSOP-8). Pin functions are defined per channel count and package; for example, TSSOP-14 assigns dedicated pins for all four outputs (1,7,8,14) and eight inputs (2,3,5,6,9,10,12,13), unlike the dual-channel variants. Migration requires PCB redesign.
What thermal performance can be expected from the TLV9044QPWRQ1 in TSSOP-14 package?
In the PW (TSSOP-14) package, the TLV9044QPWRQ1 has a junction-to-ambient thermal resistance (RθJA) of 127.6°C/W. At maximum 125°C ambient and 40µA total quiescent current (4 × 10µA), self-heating is negligible (<0.5°C), ensuring stable offset and drift performance. For high-power transient conditions, the junction-to-board (RθJB = 83.8°C/W) and junction-to-case (top) (RθJC(top) = 60.6°C/W) values support effective PCB copper pour or heatsink design.
