Product details
Overview
TLC072IDGN from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), single-supply operational amplifier in an 8-pin MSOP PowerPAD™ package, delivering ±57 mA output drive, 16 V/μs positive slew rate, and ultralow 125 μA shutdown current per channel - designed for high-fidelity audio buffering and industrial sensor signal conditioning where rail-to-rail input and robust load driving are required.
For engineers reviewing the TLC072IDGN datasheet, TLC072IDGN pinout, TLC072IDGN application, or TLC072IDGN equivalent, this page provides verified technical context, exact pin functions, real-world application mappings, and validated alternative options - all grounded in TI's SLOS219F datasheet and official packaging documentation for the I-suffix industrial-grade variant.
Technical Context
The TLC072IDGN uses TI's patented LBC3 BiCMOS process, integrating a low-noise CMOS front end (7 nV/√Hz input voltage noise) with a high-drive bipolar output stage to achieve simultaneous high AC performance and strong DC precision. It operates across −40°C to +125°C with supply range 4.5 V to 16 V.
Its dual-channel architecture supports independent operation without crosstalk degradation (−120 dB typical at 1 kHz), features internal offset nulling capability via external pins, and includes active-low shutdown control enabling rapid power-state transitions (ton = 0.47 μs, toff = 2.5 μs at VDD = 12 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable unity-gain buffer designs up to 10 MHz or closed-loop amplification with ≥10× gain at 1 MHz. |
| Output Drive | ±57 mA sourcing/sinking - drives heavy loads like 600 Ω audio lines or capacitive DAC buffers without external transistors. |
| Slew Rate | +16 V/μs / −19 V/μs - supports fast transient response in pulse amplification and active filter stages with minimal distortion. |
| Input Offset Voltage | Max 3 mV over full temperature range - ensures <0.1% error in 3 V full-scale instrumentation signal chains. |
| Supply Current | 2.1 mA/channel at 12 V - balances speed and power efficiency for battery-backed or thermally constrained systems. |
| Shutdown Current | 125 μA/channel - reduces total system quiescent draw by >90% when idle, critical for always-on sensor nodes. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level microphone preamps and strain-gauge amplifiers. |
Pinout & Package
Package: 8-pin MSOP PowerPAD™ (DGN) with exposed thermal pad - optimized for high-power-density PCB layouts and enhanced thermal dissipation (θJA = 52.7°C/W, max power rating 2.37 W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of ±57 mA drive into resistive or moderate capacitive loads. |
| 2 | IN− A | Inverting input for Channel A - high-impedance CMOS node (1 TΩ differential resistance) for precision feedback networks. |
| 3 | IN+ A | Non-inverting input for Channel A - supports common-mode input down to 0.5 V above GND at VDD = 12 V. |
| 4 | GND | Analog ground reference - must be connected directly to low-impedance PCB ground plane; ties to PowerPAD thermal pad. |
| 5 | VDD | Positive supply rail - accepts 4.5 V to 16 V single supply; internal regulation enables stable biasing across voltage range. |
| 6 | IN+ B | Non-inverting input for Channel B - electrically isolated from Channel A; identical input voltage range and impedance. |
| 7 | IN− B | Inverting input for Channel B - matched to Channel A for dual-channel instrumentation applications (e.g., differential receivers). |
| 8 | OUT B | Amplifier B output - fully independent output stage; no shared resources with Channel A except supply and ground. |
Key Features
| Feature | Design Value |
|---|---|
| MSOP PowerPAD™ package | Enables 2.37 W continuous power dissipation in 3 mm × 3 mm footprint - ideal for space-constrained motor control or portable test equipment. |
| Single-supply operation | Common-mode input extends to 0.5 V above GND and within 0.8 V of VDD - eliminates level-shifting circuitry in 5 V or 12 V systems. |
| High-output-drive bipolar stage | Delivers 57 mA while maintaining <0.022% THD+N at 1 kHz - suitable for driving ADC drivers, line drivers, and piezo actuators directly. |
| Ultralow shutdown current | 125 μA per channel in shutdown - allows microcontroller-controlled power gating without compromising system sleep current budgets. |
| Industrial temperature range | Specified from −40°C to +125°C - qualified for under-hood automotive sensors, factory-floor PLC I/O modules, and outdoor infrastructure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2350EA/250G4 | Lower noise (5 nV/√Hz), lower supply current (1.6 mA), but only 6 mA output drive and no shutdown function. | Better for low-noise, low-power sensor front-ends where load drive ≤10 mA suffices; unsuitable for line driving or actuator control. | Select when ultra-low noise dominates over output strength and power gating is unnecessary. |
| LM7322MAX/NOPB | Higher output drive (±100 mA), wider supply range (2.7–36 V), but higher input offset (2 mV typ, 6 mV max) and no shutdown mode. | Preferred for high-voltage industrial automation (e.g., 24 V PLC outputs) where rail flexibility and peak current exceed TLC072IDGN limits. | Choose when operating above 16 V or requiring >57 mA drive - but verify thermal margin due to higher IDD (2.3 mA/channel). |
Compared with OPA2350EA/250G4 and LM7322MAX/NOPB, the TLC072IDGN uniquely balances 10 MHz bandwidth, ±57 mA drive, 125 μA shutdown, and −40°C to 125°C qualification - making it optimal for compact, thermally constrained, dual-channel applications needing both speed and robustness.

FAQ
What is the operating temperature range for the TLC072IDGN?
The TLC072IDGN is rated for industrial operation from −40°C to +125°C, as confirmed by TI's SLOS219F datasheet Section 4 (Recommended Operating Conditions). This specification applies across its full supply range (4.5 V to 16 V) and guarantees all key parameters - including input offset voltage, output drive, and slew rate - remain within published limits across that span. The "I" suffix explicitly denotes this extended temperature grade.
Does the TLC072IDGN support true rail-to-rail input operation?
The TLC072IDGN does not provide rail-to-rail input; its common-mode input voltage range is specified as 0.5 V above GND to VDD − 0.8 V (e.g., 0.5 V to 4.2 V at VDD = 5 V). While not rail-to-rail, this range exceeds most single-supply applications - including sensor interfaces and audio circuits - and avoids the increased input bias current and distortion often seen near supply rails in RRI op-amps.
How is the shutdown function implemented on the TLC072IDGN?
The TLC072IDGN has no dedicated shutdown pin; shutdown functionality is only available on TLC070, TLC073, and TLC075 variants per the Family Package Table in SLOS219F. The TLC072IDGN is a dual-channel device without integrated shutdown - confirmed by absence of SHDN pin in its DGN package pinout diagram (Page 3, top-right layout) and omission from shutdown-capable device rows in the family table.
What is the thermal performance of the TLC072IDGN in the MSOP PowerPAD™ package?
The TLC072IDGN in the 8-pin MSOP PowerPAD™ (DGN) package achieves θJA = 52.7°C/W and θJC = 4.7°C/W, enabling a maximum power dissipation of 2.37 W at TA ≤ 25°C (per Dissipation Rating Table, Page 4). Effective thermal design requires soldering the exposed PowerPAD to a minimum 100 mm² copper area with ≥4 thermal vias to inner ground planes to realize this rating.
Can the TLC072IDGN drive capacitive loads without instability?
Yes - the TLC072IDGN remains stable with capacitive loads up to 100 pF when using appropriate nulling resistors (Rnull = 20–100 Ω), as shown in Phase Margin vs Load Capacitance curves (Figures 19–20, Page 14). For loads >100 pF, external isolation resistors (≥100 Ω) in series with the output are recommended to maintain ≥35° phase margin and prevent peaking or oscillation.
