Product details
Overview
TLC072IDR from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), single-supply operational amplifier with high-output drive (±55 mA), 16 V/μs positive slew rate, and ultralow shutdown current (125 μA/channel). It operates from 4.5 V to 16 V and delivers low input offset voltage (60 μV typ) and low input noise (7 nV/√Hz at 1 kHz), making it suitable for precision audio line drivers and industrial sensor signal conditioning.
For engineers reviewing the TLC072IDR datasheet, TLC072IDR pinout, TLC072IDR application, or TLC072IDR equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options - all grounded in TI's SLOS219F datasheet and official packaging documentation.
Technical Context
The TLC072IDR uses TI's patented LBC3 BiCMOS process, combining a high-impedance CMOS front end for low noise and bias current with a bipolar output stage enabling ±55 mA drive into heavy loads. Its rail-to-rail input common-mode range (0.5 V to VDD − 0.8 V) and fast turn-on time (0.47 μs at VDD = 12 V) support robust performance in dynamic single-supply systems.
It features no internal shutdown control on the TLC072 variant (per family table), distinguishing it from TLC070/TLC073/TLC075. The device is rated for −40°C to 125°C operation and exhibits stable phase margin (≥37°) across load capacitances up to 100 pF when properly compensated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - supports stable unity-gain buffering of signals up to ~8 MHz with <0.1% settling error. |
| Slew Rate | +16 V/μs / −19 V/μs - enables clean 10-Vpp output at 100 kHz without slewing distortion in driving 600-Ω loads. |
| Output Drive | IOH = 57 mA at VDD − 1.5 V; IOL = 55 mA at 0.5 V - drives demanding loads like relay coils, LED strings, or low-Z audio lines directly. |
| Input Offset Voltage | 60 μV typical (25°C), ≤2 mV max over full temperature range - ensures sub-mV DC accuracy in precision transducer amplifiers. |
| Supply Range | 4.5 V to 16 V single supply - compatible with 5 V, 12 V, and wide-input industrial rails without level-shifting circuitry. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and strain-gauge bridge amplifiers where signal levels are <100 μV. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, motor control feedback, and industrial PLC analog I/O modules. |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel (R suffix), RoHS-compliant, 150°C max junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of sourcing/sinking ±55 mA; requires local 0.1-μF bypass capacitor near VDD pin. |
| 2 | IN− A | Inverting input for channel A - high-impedance CMOS node (1 TΩ typical); sensitive to PCB leakage and EMI coupling. |
| 3 | IN+ A | Non-inverting input for channel A - common-mode range extends to within 0.5 V of GND and VDD − 0.8 V. |
| 4 | GND | Analog ground reference - must be low-impedance star point; separate from digital ground if mixed-signal layout used. |
| 5 | IN+ B | Non-inverting input for channel B - electrically identical to Pin 3; supports independent dual-channel configurations. |
| 6 | IN− B | Inverting input for channel B - matched to Pin 2; differential pair tracking ensures <10 μV inter-channel offset drift. |
| 7 | OUT B | Amplifier B output - fully independent of OUT A; supports split-load or parallel-output configurations. |
| 8 | VDD | Positive supply rail - accepts 4.5–16 V; thermal pad not present (SOIC-8 D package has no PowerPAD). |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS architecture | Combines CMOS input stage (low Ib, low In) with bipolar output (high Iout, low Zo) - eliminates need for external driver stages. |
| Rail-to-rail input range | Operates with inputs as low as 0.5 V above GND and as high as VDD − 0.8 V - simplifies level translation in 3.3 V/5 V interfacing. |
| High PSRR & CMRR | 130 dB PSRR and ≥95 dB CMRR at DC - rejects power supply ripple and common-mode interference in noisy industrial environments. |
| Low THD+N | 0.005% at 1 kHz, 8 Vpp, RL = 10 kΩ - meets Class AB audio line-driver requirements without post-filtering. |
| Stable with capacitive loads | Maintains ≥37° phase margin up to 100 pF CL - allows direct connection to long cables or ADC input capacitors without isolation resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel general-purpose op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Lower bandwidth (3 MHz), higher input offset (3 mV max), no guaranteed 125°C operation - BiFET architecture, higher input bias current (200 pA vs 100 pA). | Acceptable for cost-sensitive audio preamps or non-critical industrial monitoring where speed and precision are relaxed. | Select TL072CDR only if design tolerates 3× lower bandwidth and 50× higher input offset; verify thermal derating at >85°C. |
| OPA2340UA | Rail-to-rail input/output, lower noise (4.5 nV/√Hz), but lower output drive (25 mA), narrower supply (2.7–5.5 V), and no 125°C rating. | Better suited for portable battery-powered instrumentation, not for 12 V industrial or automotive use. | Choose OPA2340UA only for low-voltage, low-noise, RRO applications - incompatible with 12 V supplies or high-current loads required by TLC072IDR use cases. |
Compared with TL072CDR, TLC072IDR delivers 3.3× higher bandwidth and 50× lower input offset for precision closed-loop control; versus OPA2340UA, it supports wider supply range and 2.2× higher output current but lacks rail-to-rail output swing - critical for low-voltage signal chains.

FAQ
What is the operating temperature range for the TLC072IDR?
The TLC072IDR is specified for operation from −40°C to +125°C, matching the "I" temperature grade per TI's SLOS219F datasheet. This makes it suitable for under-hood automotive, industrial motor drives, and outdoor equipment where ambient temperatures exceed standard commercial limits. The device maintains full parameter performance across this range, including input offset voltage ≤2 mV and output drive ≥50 mA at 125°C.
Does the TLC072IDR have a shutdown pin?
No, the TLC072IDR does not include a shutdown function. Per the family package table and pinout diagrams in the SLOS219F datasheet, shutdown capability is only present on TLC070, TLC073, and TLC075 variants - the TLC072 and TLC074 lack SHDN pins entirely. Therefore, power management for TLC072IDR must be implemented externally via supply switching or enable circuitry.
What package type is used for the TLC072IDR?
The TLC072IDR uses the SOIC-8 (D) package - an 8-pin small-outline integrated circuit with 1.27 mm pitch, 3.9 mm body width, and tape-and-reel (R) packaging. It is distinct from MSOP or PowerPAD variants (e.g., TLC072IDGN); the "D" suffix confirms SOIC-8, and the "R" denotes reel packaging per TI's ordering conventions.
Can the TLC072IDR drive a 600-Ω load at 10 Vpp?
Yes, the TLC072IDR can drive a 600-Ω load at 10 Vpp. At VDD = 12 V, its high-level output voltage remains ≥10.3 V with 50 mA sink/source (Figures 7–8), and its 16 V/μs slew rate supports distortion-free 10 Vpp sine waves up to ~160 kHz. Total harmonic distortion plus noise stays below 0.022% at 1 kHz under these conditions, meeting professional audio line-driver standards.
How does the TLC072IDR compare to the TL072 in terms of input bias current?
The TLC072IDR specifies a maximum input bias current of 100 pA over temperature (−40°C to 125°C), whereas the TL072CDR has a typical value of 200 pA but no guaranteed max over temperature. This 2× lower and bounded Ib enables higher-impedance sensor interfaces (e.g., pH electrodes or piezoelectric sensors) without significant DC error, especially in designs operating across wide temperature ranges where TL072 bias current can increase significantly.
