Product details
Overview
TLC070CD 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), featuring 16 V/μs positive slew rate, 7 nV/√Hz input voltage noise, and shutdown capability. It serves as a precision gain stage or buffer in audio line drivers, sensor signal conditioning, and industrial analog front-ends where rail-to-rail output swing and low distortion are required.
For engineers reviewing the TLC070CD datasheet, TLC070CD pinout, TLC070CD application, or TLC070CD equivalent, this page delivers verified electrical specifications, SOIC-8 package layout, real-world use cases in single-supply instrumentation, and validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLC070CD integrates a CMOS input stage for ultralow input bias current (≤100 pA) and high input impedance (>1 TΩ), paired with a bipolar output stage enabling ±55 mA drive into heavy loads while maintaining stability with capacitive loads up to 100 pF. Its BiMOS architecture delivers 300% higher bandwidth and 60% lower noise than legacy TL07x predecessors.
It supports active shutdown (SHDN pin) reducing supply current to 125 μA per channel, features offset nulling pins (1 and 8), and operates across 0°C to 70°C - confirmed by C-suffix designation. Input common-mode range extends from 0.5 V to VDD − 0.8 V, enabling direct interfacing with microcontroller ADCs and DACs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables stable closed-loop operation at unity gain up to 10 MHz, suitable for audio and medium-speed data acquisition. |
| Slew Rate (+/−) | 16 / 19 V/μs - supports fast settling of large-signal transients (e.g., 1-V step in <0.2 μs), critical for pulse amplification. |
| Output Drive | ±55 mA - drives 600-Ω audio loads or multiple logic inputs without external buffers, eliminating need for discrete output stages. |
| Input Noise | 7 nV/√Hz @ 1 kHz - ensures minimal added noise in low-level sensor amplification (e.g., thermocouple, strain gauge). |
| Supply Range | 4.5 V to 16 V single supply - compatible with 5 V and 12 V industrial rails; eliminates dual-supply complexity in embedded systems. |
| Shutdown Current | 125 μA - reduces system power by >93% during idle periods, extending battery life in portable instrumentation. |
| Input Offset Voltage | 60 μV (typ) - enables high-accuracy DC-coupled gain stages without trimming, e.g., in precision weigh-scale amplifiers. |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm body, 1.27 mm pitch, gull-wing leads. RoHS-compliant, tape-and-reel option available (TLC070CDR).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null | Connects to external potentiometer for manual input offset trimming; essential for sub-100-μV DC accuracy. |
| 2 | Inverting Input (IN−) | Differential input node; high-impedance CMOS input (≥1 TΩ) minimizes loading on source circuits. |
| 3 | Non-Inverting Input (IN+) | Differential input node; common-mode range extends to within 0.8 V of VDD, supporting high-side sensing. |
| 4 | GND | Analog ground reference; must be star-connected to minimize noise coupling in mixed-signal PCB layouts. |
| 5 | Shutdown (SHDN) | Active-high digital control: ≥2 V enables amplifier; ≤0.8 V disables output and reduces IDD to 125 μA. |
| 6 | VDD | Positive supply rail; accepts 4.5–16 V; internal regulation ensures stable biasing across full voltage range. |
| 7 | Output (OUT) | Class-AB output stage delivers ±55 mA; capable of rail-to-rail swing within 100 mV of rails under load. |
| 8 | Offset Null | Second terminal for offset nulling potentiometer; used with Pin 1 to balance input stage mismatch. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input (low IB, high Zin) with bipolar output (high Iout, low Zo) - eliminates compromise between precision and drive strength. |
| Wide Supply Range | Operates from 4.5 V to 16 V single supply - simplifies power design in 5 V/12 V systems without level-shifting or charge pumps. |
| Shutdown Mode | Reduces quiescent current to 125 μA while preserving pin states - enables rapid wake-up (<1.3 μs turn-on time) for duty-cycled sensors. |
| High Output Current | Delivers ±55 mA into resistive loads - directly drives LEDs, relays, or transmission lines without external transistors. |
| Low Input Voltage Noise | 7 nV/√Hz at 1 kHz - maintains signal integrity in low-amplitude, wideband applications like ECG front-ends or microphone preamps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | Lower bandwidth (3 MHz), higher input offset (3 mV max), no shutdown, 2× higher input noise (18 nV/√Hz). | Lacks rail-compatible output swing and single-supply optimization; requires dual supplies for full dynamic range. | Select when cost sensitivity outweighs performance needs and dual-supply infrastructure already exists. |
| OPA2134PA | Higher precision (25 μV VIO), lower noise (8 nV/√Hz), but lower output drive (±20 mA) and no shutdown mode. | Optimized for audio fidelity over drive strength; unsuitable for driving heavy or capacitive loads. | Prefer for ultra-low-distortion audio paths where load is light (≥10 kΩ) and shutdown is unnecessary. |
Compared with TL071CP and OPA2134PA, the TLC070CD uniquely balances wide bandwidth, high output current, and shutdown capability in a single SOIC-8 package - making it the only choice for space-constrained, battery-aware, single-supply systems requiring both precision and drive.

FAQ
What is the operating temperature range for the TLC070CD?
The TLC070CD is rated for commercial temperature operation from 0°C to 70°C, as indicated by its "C" suffix. This range is validated per TI's SLOS219F datasheet and applies to all electrical specifications unless otherwise noted. The device remains functional outside this range but guaranteed performance is limited to 0°C–70°C.
Does the TLC070CD support rail-to-rail input or output?
The TLC070CD does not feature rail-to-rail input; its common-mode input range is specified from 0.5 V to VDD − 0.8 V. However, its output swings within 100 mV of both rails under light loads and sustains ±55 mA drive - making it a near-rail-to-rail output amplifier ideal for single-supply systems where full rail usage isn't required at the input.
How does the shutdown function work on the TLC070CD?
The TLC070CD's SHDN pin (Pin 5) is active-high: applying ≥2 V enables normal operation, while ≤0.8 V places the amplifier in shutdown mode, reducing supply current to 125 μA per channel. Turn-on time is 0.15 μs and turn-off time is 1.3 μs - enabling fast power cycling in battery-powered sensor nodes using the TLC070CD.
Can the TLC070CD drive capacitive loads, and what is the maximum stable value?
Yes, the TLC070CD is stable with capacitive loads up to 100 pF when used in unity-gain follower configuration, as confirmed by phase margin measurements (≥32° at CL = 50 pF). For loads >100 pF, external isolation resistance (e.g., 20–100 Ω in series with output) is recommended to maintain stability - a design consideration explicitly addressed in the TLC070CD datasheet.
Is the TLC070CD pin-compatible with other op-amps in the same package?
The TLC070CD uses a standard SOIC-8 footprint with offset-null pins (1 and 8), which differs from generic op-amps like LM358 or TL071 that lack null pins. While physical package dimensions match industry-standard SOIC-8, circuit-level pin compatibility requires verification of function mapping - especially for SHDN (Pin 5) and null pins, which are unique to the TLC070CD among TI's general-purpose op-amps.
