Product details
Overview
TLV3544QPWRQ1 from Texas Instruments is a quad-channel, rail-to-rail input/output, 250-MHz unity-gain stable CMOS operational amplifier optimized for automotive video and high-speed signal conditioning. It delivers 150 V/µs slew rate, 7.5 nV/√Hz input voltage noise, >100 mA output drive, and 0.02% differential gain error - enabling precision RGB video buffering and SAR ADC driving in engine management and surround-view camera systems.
For engineers reviewing the TLV3544QPWRQ1 datasheet, TLV3544QPWRQ1 pinout, TLV3544QPWRQ1 application, or TLV3544QPWRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to +125°C), 2.5 V to 5.5 V supply range, 100-mV rail-to-rail output swing, and channel-to-channel crosstalk of –84 dB at 5 MHz - all critical for safety-critical automotive signal chains.
Technical Context
The TLV3544QPWRQ1 employs a complementary N/P-channel input stage enabling rail-to-rail common-mode input range extending 100 mV beyond both supply rails, paired with a class-AB output stage delivering 100-mV rail-to-rail swing into high-impedance loads. Its voltage-feedback architecture achieves unity-gain stability while maintaining 250-MHz small-signal bandwidth and 100-MHz gain-bandwidth product.
Designed explicitly for single-supply automotive operation (2.5 V to 5.5 V), it integrates thermal shutdown (trip at 160°C, reset at 140°C) and supports back-terminated 75-Ω video cable driving without external level-shifting. Four fully independent amplifier channels minimize inter-channel crosstalk to –84 dB at 5 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 250 MHz - enables stable +1-V/V video follower operation with minimal phase margin degradation. |
| Slew Rate | 150 V/µs - supports clean 4-V step response in ≤11 ns, critical for fast transient video and sensor signals. |
| Input Voltage Noise | 7.5 nV/√Hz at 1 MHz - ensures low-noise amplification of weak signals from automotive sensors and photodiodes. |
| Rail-to-Rail I/O | Input extends (V−) −0.1 V to (V+) +0.1 V; output swings within 100 mV of rails - maximizes dynamic range on 3.3 V or 5 V supplies. |
| Differential Gain/Phase | 0.02% / 0.09° (NTSC, RL = 150 Ω) - meets broadcast-grade video fidelity requirements for backup camera processing. |
| Supply Range | 2.5 V to 5.5 V - compatible with automotive 3.3 V and 5 V domains, including battery-supplied ADAS modules. |
| Quiescent Current | 5.2 mA per channel - balances high-speed performance with power efficiency in always-on vision systems. |

Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation, HBM ±1000 V, CDM ±250 V - suitable for powertrain and ADAS ECUs. |
| 0.1-dB gain flatness to 40 MHz | Ensures amplitude consistency across NTSC/PAL video bandwidth without post-processing equalization. |
| Channel-to-channel crosstalk –84 dB @ 5 MHz | Prevents interference between adjacent video channels or sensor signals in compact multi-amplifier layouts. |
| Thermal shutdown with hysteresis | Shuts down at 160°C junction; resumes at 140°C - protects against sustained overloads in enclosed enclosures. |
| Low input bias current (3 pA) | Minimizes voltage error in high-impedance sensor interfaces (e.g., urea concentration sensors, piezoresistive elements). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4350EA/2K5 | Lower GBW (38 MHz), rail-to-rail I/O, higher quiescent current (8 mA/ch), no AEC-Q100 Grade 1 rating | Better DC precision (125 µV VOS), suited for low-frequency sensor front-ends where speed is secondary | Select when ultra-low offset and drift outweigh bandwidth needs; requires external qualification for automotive use. |
| LMH6629MA/NOPB | Higher bandwidth (1.5 GHz), higher noise (1.9 nV/√Hz), no rail-to-rail output, non-automotive grade | Targeted at RF/IF signal chains and high-frequency test equipment, not video or sensor conditioning | Choose only for >500 MHz small-signal applications; unsuitable for automotive temperature or reliability requirements. |
Compared with OPA4350EA/2K5 and LMH6629MA/NOPB, TLV3544QPWRQ1 uniquely balances 250-MHz bandwidth, AEC-Q100 Grade 1 compliance, rail-to-rail I/O, and 7.5-nV/√Hz noise - making it the only qualified solution for production automotive video and high-speed sensor signal conditioning.

FAQ
What automotive temperature range does the TLV3544QPWRQ1 support?
The TLV3544QPWRQ1 is AEC-Q100 Grade 1 qualified for continuous operation from –40°C to +125°C ambient temperature. Its electrical specifications, including offset voltage drift (±4.5 µV/°C), gain-bandwidth, and output drive, are guaranteed across this full range - essential for engine control units and radar modules exposed to under-hood thermal extremes.
Can TLV3544QPWRQ1 drive 75-Ω back-terminated video cables directly?
Yes, TLV3544QPWRQ1 is explicitly characterized for 75-Ω video cable driving in single-supply configurations. Its output stage delivers 0.02% differential gain and 0.09° differential phase error into 150-Ω resistive loads (simulating properly terminated 75-Ω lines), meeting NTSC broadcast standards without external level-shifting or AC-coupling components.
Does TLV3544QPWRQ1 include thermal protection?
Yes, TLV3544QPWRQ1 integrates an on-chip thermal shutdown circuit that disables all four amplifiers when junction temperature reaches 160°C. Operation automatically resumes once the die cools to 140°C, providing hysteresis to prevent oscillation near trip point - critical for sustained high-current operation in compact automotive enclosures.
What is the maximum continuous output current per channel of TLV3544QPWRQ1?
TLV3544QPWRQ1 delivers >100 mA continuous output current per channel at 5 V supply, with typical output swing of 4.9 V (within 100 mV of rails) into 1-kΩ load. At 3 V supply, output current capability drops to 50 mA. Peak short-circuit current reaches 200 mA, triggering thermal shutdown if sustained.
How does TLV3544QPWRQ1 achieve rail-to-rail input operation?
TLV3544QPWRQ1 uses a complementary input stage: parallel N-channel and P-channel differential pairs. The N-pair operates near V+, the P-pair near V−, with overlapping conduction across a ~600-mV transition region. This architecture extends the common-mode input range to (V−) −0.1 V to (V+) +0.1 V - enabling direct interface to sensors and ADC references without external biasing.
