Product details
Overview
TLC082QDGNRQ1 from Texas Instruments is a dual-channel automotive-grade operational amplifier using BiCMOS process technology, delivering 10 MHz bandwidth, ±57 mA output drive capability, and 8.5 nV/√Hz input voltage noise - enabling high-fidelity signal conditioning in car audio preamps and ADAS sensor interfaces.
For engineers reviewing the TLC082QDGNRQ1 datasheet, TLC082QDGNRQ1 pinout, TLC082QDGNRQ1 application, or TLC082QDGNRQ1 equivalent, key selection criteria include single-supply operation (4.5 V to 16 V), rail-to-rail input common-mode range (GND to VDD–2 V), 16 V/μs slew rate, and AEC-Q100 Grade 1 qualification for under-hood automotive use.
Technical Context
The TLC082QDGNRQ1 integrates a high-impedance, low-noise CMOS front end with a high-current bipolar output stage, enabling simultaneous high AC performance and robust load driving. Its BiCMOS architecture supports stable operation with capacitive loads up to 11 pF while maintaining ≥32° phase margin across temperature.
It operates over –40°C to +125°C junction temperature with guaranteed input offset voltage ≤3.3 mV (max), supply current ≤3.5 mA per channel, and CMRR ≥70 dB - meeting stringent requirements for engine control unit analog front ends and blind spot detection 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 radar IF amplification. |
| Slew Rate | +16 V/μs / –19 V/μs - supports fast transient response in collision warning pulse amplifiers without distortion. |
| Output Drive | ±57 mA (source/sink) - drives 600 Ω audio loads directly without external buffers in infotainment systems. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signals from HVAC temperature sensors or steering torque transducers. |
| Supply Range | 4.5 V to 16 V single supply - accommodates battery voltage fluctuations in 12 V automotive systems without regulation. |
| Input Offset | 60 μV typical (3.3 mV max) - minimizes DC error in precision ECU current-sense amplifiers. |
| Temp Range | –40°C to +125°C operating junction temperature - qualified for placement near engine compartments or powertrain modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7332QMA/NOPB | Higher 24 MHz GBW but lower output drive (±60 mA typ), no AEC-Q100 Grade 1 rating; 10-pin VSSOP package. | Not qualified for under-hood use; better suited for cabin-mounted infotainment vs. ECU-integrated designs. | Select when higher bandwidth is critical and temperature grade can be relaxed to industrial. |
| TSV912IQ2T | Lower 8 MHz GBW, 5.5 V max supply, 1.1 mA/ch supply current; AEC-Q100 Grade 1, 8-pin DFN. | Optimized for ultra-low-power body electronics (e.g., mirror controls), not high-drive radar or audio applications. | Select for space-constrained, low-voltage nodes where drive strength and bandwidth are secondary to quiescent current. |
Compared with LM7332QMA/NOPB and TSV912IQ2T, the TLC082QDGNRQ1 uniquely balances 10 MHz bandwidth, ±57 mA drive, and full AEC-Q100 Grade 1 qualification in an 8-pin MSOP-PowerPAD - making it the only option among the three qualified for direct integration into engine bay signal chains.

FAQ
What is the maximum capacitive load the TLC082QDGNRQ1 can drive while maintaining stability?
The TLC082QDGNRQ1 maintains ≥32° phase margin with capacitive loads up to 11 pF when configured as a unity-gain follower, as verified in Figure 19 of the SLOS510E datasheet. For loads exceeding 11 pF, external series resistance (Rnull) is required at the output to preserve stability - a design detail confirmed in the "Phase Margin vs Load Capacitance" characterization data for the TLC082QDGNRQ1.
Does the TLC082QDGNRQ1 support dual-supply operation?
Yes, the TLC082QDGNRQ1 supports dual-supply operation with ±2.25 V to ±8 V rails, as specified in Section 6.3 "Recommended Operating Conditions" of the SLOS510E datasheet. This flexibility allows use in legacy test equipment or hybrid systems alongside single-supply automotive domains - a capability explicitly validated for the TLC082QDGNRQ1 across its full temperature range.
What is the thermal resistance (RθJA) of the TLC082QDGNRQ1 in its MSOP-PowerPAD package?
The TLC082QDGNRQ1 has a junction-to-ambient thermal resistance (RθJA) of 58.1°C/W in the 8-pin MSOP-PowerPAD (DGN) package, per Table 6-4 "Thermal Information" in the SLOS510E datasheet. This value assumes standard JEDEC 2-layer board conditions and confirms the device's suitability for thermally constrained automotive PCBs without forced airflow.
Is the TLC082QDGNRQ1 pin-compatible with the legacy TL082-Q1?
No, the TLC082QDGNRQ1 is not pin-compatible with the TL082-Q1. While both are dual op-amps, the TLC082QDGNRQ1 uses an 8-pin MSOP-PowerPAD (DGN) footprint with PowerPAD thermal pad, whereas TL082-Q1 variants commonly use SOIC-8 or TSSOP-8 packages without exposed pads - requiring PCB layout revision for migration. This mechanical incompatibility is documented in TI's orderable addendum for the TLC082QDGNRQ1.
What is the input common-mode voltage range for the TLC082QDGNRQ1 at 12 V supply?
At VDD = 12 V, the TLC082QDGNRQ1 supports an input common-mode voltage range of 0 V to 10.5 V, as specified in Section 6.5 "Electrical Characteristics" of the SLOS510E datasheet. This rail-to-rail input capability - extending to GND and within 1.5 V of VDD - enables direct interfacing with 0–10 V sensor outputs in HVAC and chassis control systems without external level-shifting circuitry.
