Product details
Overview
TLC072QDRQ1 from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier qualified for automotive applications (–40°C to 125°C), operating from single supplies of 4.5 V to 16 V, with 16 V/µs positive slew rate and 7 nV/√Hz input voltage noise - used in precision sensor signal conditioning and automotive audio front-ends.
For engineers reviewing the TLC072QDRQ1 datasheet, TLC072QDRQ1 pinout, TLC072QDRQ1 application, or TLC072QDRQ1 equivalent, this page delivers verified electrical parameters, automotive-grade thermal performance, SOIC-8 package layout guidance, and real-world drive capability data for single-supply op-amp selection in safety-critical systems.
Technical Context
The TLC072QDRQ1 employs TI's LBC3 BiCMOS process, integrating a low-noise CMOS input stage (1000 GΩ differential input resistance, 0.7 pA typical input bias current) with a high-current bipolar output stage capable of sourcing 57 mA and sinking 55 mA at rail-to-rail load conditions. Its 10 MHz gain-bandwidth product and 19 V/µs negative slew rate support fast settling in active filter and driver circuits.
Designed for single-supply operation, it features rail-to-rail common-mode input range (VDD – 0.8 V max), 60 µV typical input offset voltage, and 130 dB supply voltage rejection ratio - enabling accurate DC-coupled amplification in battery-powered automotive ECUs and industrial analog I/O modules without dual-rail complexity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - supports stable unity-gain buffer operation up to audio and ultrasonic frequencies in sensor interfaces. |
| Slew Rate (+/−) | 16 V/µs / 19 V/µs - enables <0.4 µs settling to 0.1% for 1-V step signals, critical for fast pulse amplification. |
| Output Drive | ±55 mA - drives 600 Ω loads directly without external buffers, reducing BOM count in audio line drivers. |
| Input Noise | 7 nV/√Hz @ 1 kHz - preserves SNR in low-level thermocouple or strain gauge signal chains. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and wide-range automotive battery rails including cold-crank transients. |
| Temp Range | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and ADAS subsystems. |
| Offset Voltage | 60 µV typ - minimizes DC error in precision instrumentation amplifiers and closed-loop motor control feedback paths. |
Pinout & Package
Package: 8-pin SOIC (D package), surface-mount, 3.91 mm × 4.90 mm footprint, 1.75 mm height, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | High-current output node; capable of ±55 mA drive into resistive or capacitive loads up to 100 pF. |
| 2 (IN−1) | Channel 1 inverting input | CMOS input with 22.9 pF common-mode capacitance; requires careful PCB layout to avoid instability with large feedback resistors. |
| 3 (IN+1) | Channel 1 noninverting input | High-impedance node (1000 GΩ); used for reference or sensor input; benefits from guard ring and low-noise routing. |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must connect to low-impedance ground plane beneath device. |
| 5 (IN+2) | Channel 2 noninverting input | Independent high-Z input; shares same noise and offset characteristics as Pin 3. |
| 6 (IN−2) | Channel 2 inverting input | Matches Pin 2 electrically; supports dual-channel configurations like differential receivers or stereo preamps. |
| 7 (OUT2) | Channel 2 output | Functionally identical to Pin 1; enables independent dual-amplifier operation without crosstalk degradation (–70 dB typical). |
| 8 (VDD) | Positive supply rail | Accepts 4.5–16 V; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling per channel for stability. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS architecture | Combines CMOS input (ultra-low IB, high Z) with bipolar output (high drive, low Zo) - eliminates need for discrete input/output stage partitioning. |
| Rail-to-rail input range | Common-mode extends to VDD – 0.8 V and GND + 0.5 V - enables direct interfacing with 0–5 V sensors and microcontroller ADC references. |
| Ultralow power shutdown | 125 µA/channel quiescent current in shutdown - reduces system standby power in always-on automotive modules. |
| High PSRR & CMRR | 130 dB supply rejection and 100 dB common-mode rejection - maintains accuracy in noisy engine-bay environments with shared power rails. |
| Offset null compatibility | Supports external nulling via pins 1/8 (per channel) using 20 kΩ potentiometer - allows trimming of residual offset in precision measurement bridges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, automotive-grade op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7332QMA/NOPB | Higher supply current (2.5 mA/ch), lower bandwidth (20 MHz), no shutdown mode, same SOIC-8 package. | Better for high-speed active filters but less suitable for ultra-low-power wake-up circuits due to lack of shutdown. | Select when >15 MHz bandwidth is required and shutdown is unnecessary; verify thermal dissipation at 125°C. |
| TSV912IQ2T | Lower drive (60 mA sink only), lower noise (5.5 nV/√Hz), wider supply (2.7–16 V), same temp grade and SOIC-8. | Optimized for low-voltage sensor nodes; lacks symmetric sourcing/sinking capability needed for AC-coupled audio. | Prefer for battery-powered ADAS subsystems below 5 V; avoid where bidirectional 50 mA drive into 600 Ω is required. |
Compared with LM7332QMA/NOPB and TSV912IQ2T, the TLC072QDRQ1 uniquely balances 10 MHz bandwidth, symmetric ±55 mA output drive, and 125 µA shutdown current - making it optimal for automotive analog front-ends requiring both speed and power efficiency across wide supply and temperature ranges.

FAQ
What is the maximum capacitive load the TLC072QDRQ1 can drive without oscillation?
The TLC072QDRQ1 remains stable driving up to 100 pF directly, but for loads >10 pF, TI recommends adding a 20–100 Ω series resistor (RNULL) between the output pin and the capacitive load. This isolates the output stage from phase shift introduced by the load capacitance, preserving ≥35° phase margin per the datasheet's Figure 19 and 20. The TLC072QDRQ1's robust bipolar output stage makes it significantly more tolerant than standard CMOS op-amps.
Does the TLC072QDRQ1 support true rail-to-rail output swing?
No - the TLC072QDRQ1 does not provide rail-to-rail output. Its output typically swings to within 1.5 V of VDD (VOH ≈ VDD – 1.5 V at 50 mA) and to within 0.5 V of GND (VOL ≈ 0.5 V at 50 mA), as specified in the Electrical Characteristics table for VDD = 5 V and 12 V. This limited swing is inherent to its bipolar output stage and must be accounted for in signal chain headroom planning.
How does the TLC072QDRQ1 handle input overvoltage beyond the supply rails?
The TLC072QDRQ1 has absolute maximum differential input voltage rating of ±VDD, meaning inputs may exceed either rail by up to the full supply voltage (e.g., ±16 V for VDD = 16 V). However, continuous operation outside the common-mode range (GND + 0.5 V to VDD – 0.8 V) risks increased offset drift and reduced CMRR. Internal ESD protection diodes clamp inputs to rails, but sustained overvoltage requires external limiting resistors per TI's Application Report SLOA086.
Can the TLC072QDRQ1 be used in single-supply photodiode transimpedance amplifiers?
Yes - the TLC072QDRQ1 is well-suited for single-supply photodiode TIA designs due to its 22.9 pF common-mode input capacitance, 7 nV/√Hz voltage noise, and 1000 GΩ input resistance. For optimal performance, bias the photodiode cathode at VDD/2 using a low-noise resistor divider, use a feedback capacitor (e.g., 1–10 pF) to control bandwidth and peaking, and keep traces short to minimize stray capacitance at the inverting input.
Is the TLC072QDRQ1 pin-compatible with the standard TLC072?
Yes - the TLC072QDRQ1 uses the identical SOIC-8 (D) package and pinout as the commercial-grade TLC072, including identical terminal functions (Pins 1–8) and footprint dimensions. The "Q1" suffix denotes AEC-Q100 qualification and extended temperature screening (–40°C to +125°C), but all electrical and mechanical interfaces remain fully compatible for drop-in replacement in automotive redesigns.
