Product details
Overview
TLC084QPWPRQ1 from Texas Instruments is a quad-channel automotive-grade operational amplifier using BiCMOS process technology, delivering 10 MHz bandwidth, ±55 mA output drive capability, and 8.5 nV/√Hz input voltage noise across –40°C to 125°C. It operates from single 4.5 V to 16 V supplies and serves as a high-output-drive signal conditioner in engine control units and ADAS sensor interfaces.
For engineers reviewing the TLC084QPWPRQ1 datasheet, TLC084QPWPRQ1 pinout, TLC084QPWPRQ1 application, or TLC084QPWPRQ1 equivalent, key selection criteria include guaranteed ground-sensing input common-mode range (VICR = GND to VDD–2 V), low 60 μV typical input offset voltage, high slew rate (16 V/μs positive, 19 V/μs negative), and AEC-Q100 Grade 1 qualification for automotive systems.
Technical Context
The TLC084QPWPRQ1 integrates a high-impedance, low-noise CMOS front end with a high-current bipolar output stage-enabling simultaneous high AC performance (10 MHz GBW, 19 V/μs slew) and robust DC precision (3300 μV max VIO over temperature). Its rail-to-rail input stage supports single-supply operation down to 4.5 V while maintaining full common-mode range to ground.
Designed specifically for automotive environments, it features AEC-Q100 qualified thermal performance (RθJA = 40°C/W in HTSSOP), ±2000 V HBM ESD rating, and stable operation into capacitive loads up to 100 pF without external compensation-critical for driving long traces in body electronics and radar signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable closed-loop operation at unity gain up to 10 MHz for fast sensor signal conditioning. |
| Output Drive | ±55 mA continuous output current - drives heavy loads such as 600 Ω audio lines or capacitive ADC inputs without external buffers. |
| Slew Rate | 16 V/μs (positive), 19 V/μs (negative) - supports clean amplification of fast transients in collision warning pulse signals. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - preserves SNR in low-level analog front-ends like blind spot radar IF stages. |
| Supply Range | 4.5 V to 16 V single supply - accommodates wide battery voltage variation in automotive 12 V systems including cold-crank conditions. |
| Input Offset Voltage | 60 μV typical (3300 μV max over temp) - ensures accurate DC-coupled amplification in HVAC temperature sensing circuits. |
| Common-Mode Range | GND to VDD–2 V - allows direct interfacing with ground-referenced sensors without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2902QPWRQ1 | Lower bandwidth (1.2 MHz), lower output drive (±40 mA), higher input offset (7000 μV max), no guaranteed ground-sensing VICR. | Targeted for cost-sensitive, low-speed automotive functions (e.g., basic lighting control) where precision and speed are secondary. | Select when budget constraints outweigh performance requirements and full ground-sensing input is not needed. |
| TSV914IQDT | Higher bandwidth (20 MHz), lower supply current (800 μA/ch), but only rated to 105°C and lacks AEC-Q100 Grade 1 certification. | Suitable for industrial or consumer-grade infotainment displays-not qualified for under-hood or safety-critical chassis applications. | Choose for non-automotive or cabin-only designs requiring higher speed and lower power, where extended temperature and automotive qualification are unnecessary. |
Compared with LM2902QPWRQ1 and TSV914IQDT, the TLC084QPWPRQ1 uniquely balances automotive-grade reliability (–40°C to 125°C, AEC-Q100), high output drive (±55 mA), and precision (60 μV VIO typ) - making it optimal for ADAS sensor signal chains and powertrain control where both speed and ruggedness are mandatory.

FAQ
What is the maximum operating temperature range for the TLC084QPWPRQ1?
The TLC084QPWPRQ1 is qualified per AEC-Q100 Grade 1 and operates reliably from –40°C to +125°C ambient temperature. This rating applies to the full device functionality-including bandwidth, output drive, and input offset specifications-as verified across temperature and voltage corners in TI's production test flow. The TLC084QPWPRQ1 maintains its 10 MHz gain-bandwidth and ±55 mA output capability across this entire range.
Does the TLC084QPWPRQ1 support true rail-to-rail input operation?
The TLC084QPWPRQ1 supports input common-mode voltage from GND to VDD–2 V, enabling true ground-sensing operation but not full rail-to-rail input. Its CMOS input stage allows direct interfacing with ground-referenced sensors such as thermistors and bridge circuits without level-shifting components. However, the upper limit remains VDD–2 V-not VDD-so signals near the positive rail require attenuation or biasing.
Can the TLC084QPWPRQ1 drive capacitive loads without oscillation?
Yes-the TLC084QPWPRQ1 is designed for stability into capacitive loads up to 100 pF with appropriate layout (short traces, proper grounding). Data sheet Figure 19–22 confirm stable phase margin (>32°) and gain margin (>2.2 dB) at CL = 50 pF across temperature and supply voltage. For loads >100 pF, TI recommends adding a small series resistor (Rnull) between output and load per Figure 37 in the datasheet.
What is the typical supply current per channel for the TLC084QPWPRQ1?
The TLC084QPWPRQ1 draws 1.9 mA per channel at VDD = 5 V and 25°C, increasing to 2.9 mA per channel at VDD = 12 V and 25°C. Total quiescent current for all four channels is therefore 7.6 mA at 5 V and 11.6 mA at 12 V. These values remain within ±20% over the full –40°C to 125°C temperature range, as specified in Section 6.5 and 6.6 of the SLOS510E datasheet.
Is the TLC084QPWPRQ1 pin-compatible with any industry-standard quad op-amp packages?
No-the TLC084QPWPRQ1 uses a proprietary 20-pin HTSSOP (PWP) package with non-standard pinout optimized for thermal performance and channel separation. It is not pin-compatible with SOIC-14, TSSOP-14, or VSSOP-14 quad op-amps. Layout redesign is required when migrating from standard packages; refer to TI's PWP mechanical drawing SLMS204 for footprint and solder mask details.
