Product details
Overview
TLC071CDGN from Texas Instruments is a single-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V). It features ultralow input offset voltage (60 µV typ), low input noise (7 nV/√Hz), and integrated shutdown mode (125 µA per channel). It is used in precision audio line drivers, industrial sensor signal conditioning, and high-current analog output stages.
For engineers reviewing the TLC071CDGN datasheet, TLC071CDGN pinout, TLC071CDGN application, or TLC071CDGN equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The TLC071CDGN employs TI's patented LBC3 BiCMOS process, combining a high-impedance, low-noise CMOS front end with a high-current bipolar output stage. This architecture enables simultaneous high AC performance (16 V/µs slew rate, 10 MHz GBW) and strong DC precision (60 µV VIO, 1.2 µV/°C drift).
It operates across commercial (0°C to 70°C) and extended industrial (−40°C to 125°C) temperature ranges, supports rail-to-rail output swing under load, and includes an active-low shutdown pin enabling fast turn-off (1.3 µs) and ultra-low quiescent current (125 µA) - critical for power-sensitive instrumentation and portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - supports stable unity-gain buffering up to 10 MHz or closed-loop amplification at higher gains with predictable phase margin. |
| Slew Rate | +16 V/µs / −19 V/µs - enables clean reproduction of fast 10–20 VPP signals at >100 kHz without slewing distortion in audio or pulse applications. |
| Output Drive | ±55 mA continuous - drives 600 Ω loads directly (e.g., professional audio lines) without external buffers or heat-sinking concerns. |
| Input Offset Voltage | 60 µV typical (25°C), ≤2 mV max over full range - minimizes DC error in precision transducer interfaces and low-level signal amplification. |
| Supply Range | 4.5 V to 16 V single supply - eliminates dual-rail complexity while supporting battery-powered (5 V) and industrial (12 V) systems. |
| Shutdown Current | 125 µA per channel - reduces system standby power by >93% vs active mode (1.9 mA), enabling efficient duty-cycled sensor front ends. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and strain-gauge bridges where signal levels are sub-mV. |
Pinout & Package
Package: 8-pin MSOP (DGN) with PowerPAD™ thermal pad - provides 2.37 W power dissipation capability and enhanced thermal performance in space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or tied to GND; no routing or trace required. |
| 2 | IN− | Inverting input - connects to feedback network; high impedance (1 TΩ) minimizes loading on preceding stage. |
| 3 | IN+ | Non-inverting input - accepts high-impedance sensor or reference signals; common-mode range extends to 0.5 V above GND and VDD − 0.8 V. |
| 4 | GND | Analog ground reference - requires low-impedance local decoupling (0.1 µF ceramic + 10 µF tantalum) adjacent to pin. |
| 5 | SHDN | Active-low shutdown control - driven low (<0.8 V) to disable amplifier; high (>2 V) to enable; compatible with 3.3 V/5 V logic. |
| 6 | VDD | Positive supply - supports 4.5–16 V; PowerPAD™ enhances thermal transfer to PCB copper pour for sustained 55 mA output. |
| 7 | OUT | Amplifier output - capable of sourcing/sinking ±55 mA into resistive or capacitive loads; short-circuit protected to 150 mA. |
| 8 | NC | No internal connection - same as Pin 1; no electrical function or thermal role. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS architecture | Combines CMOS input stage (low IB, low VIO) with bipolar output (high IO, fast SR) - eliminates trade-offs between precision and drive strength. |
| MSOP PowerPAD™ package | Thermal resistance θJA = 52.7°C/W - enables 2.37 W dissipation at 25°C ambient, supporting continuous high-current operation without heatsinks. |
| Single-supply rail-to-rail output | Swings within 0.5 V of GND and 1.5 V of VDD at ±50 mA - simplifies level-shifting in 5 V/12 V systems and improves dynamic range vs legacy op-amps. |
| Low-noise, low-distortion | 7 nV/√Hz input noise + 0.002% THD+N at 1 kHz - meets fidelity requirements for Class-D predriver stages and medical signal chains. |
| Fast enable/disable timing | Turn-on time = 0.15 µs, turn-off time = 1.3 µs - supports microsecond-scale power gating in time-multiplexed sensor arrays or burst-mode systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2771IDBVR | Lower bandwidth (2 MHz), lower output drive (±25 mA), but rail-to-rail input/output and lower supply current (1.2 mA). | Better suited for ultra-low-power, low-frequency sensor interfaces where drive strength is not critical. | Select when minimizing quiescent power is prioritized over speed and current delivery. |
| OPA2350UA | Higher bandwidth (38 MHz), lower noise (5 nV/√Hz), but no shutdown pin and limited output drive (±50 mA). | Ideal for high-fidelity audio preamplifiers and wideband data acquisition requiring minimal phase error. | Choose when maximum small-signal fidelity and settling speed outweigh shutdown functionality and thermal robustness. |
Compared with TLV2771IDBVR and OPA2350UA, the TLC071CDGN uniquely balances high-speed (10 MHz), high-current (±55 mA), and low-power shutdown (125 µA) in a thermally enhanced MSOP package - making it optimal for industrial analog I/O where reliability, drive, and power management coexist.

FAQ
What is the operating temperature range for the TLC071CDGN?
The TLC071CDGN is rated for the commercial temperature range of 0°C to 70°C, as indicated by the "C" suffix in the part number. Its absolute maximum junction temperature is 150°C, and it maintains specified performance across this full range - including parameters like input offset voltage (≤2 mV), supply current (≤3.5 mA), and output drive (≥±50 mA).
Does the TLC071CDGN support rail-to-rail input operation?
No, the TLC071CDGN does not support rail-to-rail input. Its common-mode input voltage range is specified as 0.5 V to VDD − 0.8 V (e.g., 0.5 V to 4.2 V at 5 V supply). While it operates well with inputs near GND or mid-supply, it cannot accept signals within 0.5 V of GND or 0.8 V below VDD - unlike true rail-to-rail input amplifiers such as the OPA333.
How does the shutdown pin (Pin 5) function on the TLC071CDGN?
The SHDN pin on the TLC071CDGN is active-low: driving it below 0.8 V disables the amplifier, reducing supply current to 125 µA per channel; pulling it above 2 V enables normal operation. The turn-off time is 1.3 µs and turn-on time is 0.15 µs - enabling rapid power cycling in time-division multiplexed systems without compromising stability.
Can the TLC071CDGN drive capacitive loads reliably?
Yes, the TLC071CDGN is designed for moderate capacitive loads. Phase margin remains ≥32° with 50 pF load capacitance and 10 kΩ load resistance. For heavier loads (>100 pF), external isolation resistance (e.g., 20–100 Ω in series with output) is recommended to maintain stability - as confirmed by Figure 19 and 20 in the datasheet showing phase margin vs. CL.
What is the thermal performance advantage of the MSOP PowerPAD™ package used by the TLC071CDGN?
The MSOP PowerPAD™ package of the TLC071CDGN achieves θJA = 52.7°C/W and θJC = 4.7°C/W, enabling a maximum power dissipation of 2.37 W at 25°C ambient. This is over 3× higher than standard SOIC-8 (θJA ≈ 176°C/W), allowing sustained ±55 mA output without thermal derating - critical for compact industrial modules where airflow is limited.
