Product details
Overview
TLC070AID from Texas Instruments is a single-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation from 4.5 V to 16 V. It features ultralow input offset voltage (max 1400 μV over full temperature range), 16 V/μs positive slew rate, and integrated shutdown functionality - enabling precision signal conditioning in audio line drivers, sensor front-ends, and industrial analog I/O modules.
For engineers reviewing the TLC070AID datasheet, TLC070AID pinout, TLC070AID application, or TLC070AID equivalent, this page delivers verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options - all grounded in TI's SLOS219F production data sheet and family documentation.
Technical Context
The TLC070AID employs TI's patented LBC3 BiCMOS process, combining a high-input-impedance CMOS front end (1000 GΩ differential resistance) with a bipolar output stage capable of ±55 mA drive into low-impedance loads. Its rail-to-rail input common-mode range (0.5 V to VDD−0.8 V at 5 V supply) and 10 MHz gain-bandwidth product support stable unity-gain buffer and active filter configurations.
Shutdown mode reduces supply current to 125 μA per channel while maintaining fast enable/disable timing (ton = 0.47 μs, toff = 2.5 μs at VDD = 12 V). The device operates across −40°C to +125°C, with guaranteed performance including 7 nV/√Hz input voltage noise at 1 kHz and 80 dB minimum CMRR over frequency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - supports stable closed-loop operation up to 100 kHz with ≥60° phase margin into 10 kΩ//47 pF loads. |
| Output Drive | ±55 mA - drives 600 Ω audio loads or multiple logic inputs without external buffers. |
| Slew Rate | +16 V/μs / −19 V/μs - enables clean 10 VPP output at 100 kHz with <0.022% THD+N at 12 V supply. |
| Input Offset Voltage | Max 1400 μV (−40°C to +125°C) - ensures ≤1.4 mV DC error in precision gain stages without trimming. |
| Supply Range | 4.5 V to 16 V single supply - eliminates dual-rail complexity in battery-powered or industrial 12 V systems. |
| Shutdown Current | 125 μA per channel - reduces system standby power by >93% vs active mode (1.9 mA). |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouple, strain gauge). |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm body, 1.27 mm pitch, PowerPAD™ thermal pad on underside (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - unused pin; must be left floating or tied to GND for mechanical stability. |
| 2 | IN− | Inverting input - accepts feedback network for closed-loop gain configuration. |
| 3 | IN+ | Non-inverting input - connects to reference, sensor, or signal source in follower or summing topologies. |
| 4 | GND | Analog ground reference - primary return path for input bias currents and output load current. |
| 5 | SHDN | Active-high shutdown control - drives ≥2 V to enable, ≤0.8 V to disable amplifier and reduce IDD to 125 μA. |
| 6 | VDD | Positive supply rail - powers internal circuitry; requires local 0.1 μF ceramic decoupling to GND. |
| 7 | OUT | Amplified output - delivers ±55 mA into resistive or capacitive loads; thermal pad improves power dissipation. |
| 8 | NULL | No internal connection - unused pin; same handling as Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS architecture | Combines CMOS input stage (pA-level bias current) with bipolar output (high current drive), eliminating trade-offs between input impedance and output capability. |
| Wide supply range | Operates from 4.5 V to 16 V single supply - supports direct integration into 5 V microcontroller systems or 12 V industrial PLC analog modules. |
| Integrated shutdown | Reduces quiescent current to 125 μA while preserving fast wake-up (<0.5 μs), enabling power-gated sensor nodes and portable instrumentation. |
| High slew rate & bandwidth | 16 V/μs slew rate + 10 MHz GBW enables accurate reproduction of fast transients in motor control feedback or ultrasound signal paths. |
| Low input noise | 7 nV/√Hz at 1 kHz allows sub-10 μV RMS noise contribution in 20 kHz bandwidth applications like medical ECG front-ends. |
| Extended temperature range | Specified from −40°C to +125°C - qualified for under-hood automotive sensors, factory-floor transmitters, and outdoor telecom equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Single-supply rail-to-rail I/O, lower bandwidth (5.5 MHz), higher input bias current (0.5 pA vs 100 pA), no shutdown pin. | Better for ultra-low-power sensor nodes where shutdown is unnecessary; less suitable for high-current line driving. | Select when rail-to-rail output swing is critical and load current ≤20 mA; avoid if >50 mA drive or shutdown control required. |
| TLC27L2CD | Lower power (110 μA/channel), lower bandwidth (1.7 MHz), no shutdown, higher input offset (2 mV max), BiFET process. | Targeted at battery-powered metering where speed and drive are secondary to quiescent current. | Choose only for cost-sensitive, low-speed applications with <10 mA output needs; not a functional replacement for TLC070AID's drive or speed. |
Compared with OPA2340UA and TLC27L2CD, the TLC070AID uniquely delivers 10 MHz bandwidth with ±55 mA output drive and integrated shutdown - making it the only option among the three suitable for high-fidelity audio buffering and industrial analog output stages requiring both speed and robust load capability.

FAQ
What is the operating temperature range for the TLC070AID?
The TLC070AID is rated for operation from −40°C to +125°C, as confirmed by TI's SLOS219F datasheet Section 4 (Recommended Operating Conditions) and Section 5 (Electrical Characteristics). This extended industrial temperature range makes the TLC070AID suitable for under-hood automotive sensors, factory automation controllers, and outdoor telecom infrastructure where ambient temperatures exceed commercial-grade limits.
Does the TLC070AID support true rail-to-rail input operation?
The TLC070AID supports rail-to-rail input common-mode voltage range from 0.5 V above GND to VDD − 0.8 V (e.g., 0.5 V to 4.2 V at 5 V supply), as specified in the "Common-mode input voltage" parameter in Section 5 of the SLOS219F datasheet. While not extending fully to the rails, this range exceeds most single-supply op-amps and accommodates signals near GND or VDD in precision sensor and DAC buffer applications.
How does the shutdown function work on the TLC070AID?
The TLC070AID's SHDN pin (Pin 5) is an active-high control: applying ≥2 V enables normal operation, while ≤0.8 V places the amplifier in shutdown mode, reducing supply current to 125 μA per channel. Enable/disable timing is characterized at 0.47 μs (ton) and 2.5 μs (toff) under 12 V supply conditions, per Section 7 of the SLOS219F datasheet - enabling rapid power cycling in battery-operated systems.
Can the TLC070AID drive a 600 Ω load at 20 kHz with low distortion?
Yes. At VDD = 12 V, the TLC070AID delivers 0.005% THD+N into a 10 kΩ load at 1 kHz and 0.022% at 100 kHz (Section 7, SLOS219F). When driving 600 Ω, Figure 30 confirms <0.01% THD+N for VO(PP) ≤ 6 V at 1 kHz. Combined with its 16 V/μs slew rate, the TLC070AID cleanly reproduces 20 kHz sine waves at ≥2 VPP into 600 Ω without slewing-induced distortion.
What is the thermal performance of the TLC070AID in SOIC-8 (D) package?
In the SOIC-8 (D) package, the TLC070AID has a junction-to-ambient thermal resistance (θJA) of 176°C/W and junction-to-case (θJC) of 38.3°C/W, supporting a maximum power dissipation of 710 mW at TA ≤ 25°C (Section 4, Dissipation Rating Table, SLOS219F). The exposed PowerPAD™ enhances heat transfer to PCB copper, enabling sustained ±55 mA output into heavy loads without thermal shutdown in properly laid-out designs.
