Product details
Overview
TLC070AIDRG4 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 1.4 mV), low input noise (7 nV/√Hz), and integrated shutdown functionality - enabling precision signal conditioning in audio line drivers, sensor interfaces, and industrial analog front-ends.
For engineers reviewing the TLC070AIDRG4 datasheet, TLC070AIDRG4 pinout, TLC070AIDRG4 application, or TLC070AIDRG4 equivalent, this page delivers verified technical context, package-specific pin mapping, real-world application cards, and validated alternative options - all grounded in TI's SLOS219F production data sheet and official device family documentation.
Technical Context
The TLC070AIDRG4 implements a CMOS-input/bipolar-output BiMOS architecture that combines >1 GΩ differential input resistance with ±55 mA output drive capability. Its 16 V/μs positive and 19 V/μs negative slew rates support fast settling in unity-gain stable configurations, while its rail-to-rail output swing (within 0.5 V of rails at 50 mA load) enables full dynamic range utilization in 5 V and 12 V systems.
Designed for extended temperature operation (−40°C to +125°C), the device integrates a dedicated SHDN pin enabling 125 μA per-channel shutdown current. Its common-mode input range extends from 0.5 V to VDD − 0.8 V, supporting direct interfacing with ADCs and microcontroller I/O without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - supports stable closed-loop operation up to 10× gain at 1 MHz. |
| Output Drive | ±55 mA continuous output current - drives heavy loads including 600 Ω audio lines and capacitive DAC buffers. |
| Slew Rate | +16 V/μs / −19 V/μs - enables <0.39 μs settling to 0.01% for 1 V step with 10 kΩ//10 pF load. |
| Input Offset Voltage | Max 1.4 mV over full temperature range - reduces DC error in precision transimpedance and instrumentation amplifiers. |
| Supply Range | 4.5 V to 16 V single supply - operates directly from 5 V logic rails or 12 V industrial bus without regulators. |
| Shutdown Current | 125 μA per channel - cuts quiescent power by >93% during system sleep modes. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signal amplification stages. |
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 - high-impedance CMOS node (1 TΩ typical) for feedback network attachment. |
| 3 | IN+ | Non-inverting input - accepts common-mode voltages from 0.5 V to VDD − 0.8 V. |
| 4 | GND | Analog ground reference - connects to PCB ground plane; critical for noise immunity and thermal dissipation via PowerPAD. |
| 5 | SHDN | Active-low shutdown control - pulls below 0.8 V to disable amplifier and reduce IDD to 125 μA. |
| 6 | VDD | Positive supply rail - supports 4.5–16 V; PowerPAD enhances thermal performance at high output currents. |
| 7 | OUT | Amplifier output - delivers ±55 mA into resistive loads and drives ≥100 pF capacitive loads stably. |
| 8 | NULL | No internal connection - unused pin; no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS front-end (low IB, high Zin) with bipolar output stage (high Iout, low Zo) - eliminates trade-off between input precision and output drive. |
| Wide Supply Range | Operates from 4.5 V to 16 V single supply - eliminates need for dual-rail supplies in portable and industrial systems. |
| Rail-to-Rail Output Swing | Swings within 0.5 V of rails at ±50 mA - maximizes dynamic range when driving ADCs or analog switches. |
| Integrated Shutdown | Reduces supply current to 125 μA per channel - enables low-power wake-on-event architectures in battery-powered sensors. |
| Enhanced AC Performance | 10 MHz GBW and 19 V/μs negative slew rate - outperforms TL07x predecessors by 300% bandwidth and 60% lower noise. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA/2K5 | Lower bandwidth (5.5 MHz), higher quiescent current (800 μA), no shutdown pin. | Lacks power-gating capability; unsuitable for intermittent-sampling sensor nodes. | Choose when ultra-low input bias current (0.2 pA) outweighs shutdown and drive requirements. |
| TLC27L2CD | Lower output drive (10 mA), slower slew rate (0.06 V/μs), wider VIO range (10 mV max). | Cannot drive low-impedance loads or support fast transient response. | Choose only for ultra-low-power (125 μA) legacy designs where bandwidth and drive are secondary. |
Compared with OPA2340UA/2K5 and TLC27L2CD, the TLC070AIDRG4 uniquely balances 10 MHz bandwidth, ±55 mA drive, and 125 μA shutdown current - making it the only option among the three capable of simultaneously meeting high-speed, high-fidelity, and low-duty-cycle system requirements.

FAQ
What is the operating temperature range for the TLC070AIDRG4?
The TLC070AIDRG4 is rated for operation from −40°C to +125°C, matching the "I" temperature suffix designation. This extended range is confirmed in the Recommended Operating Conditions table of the SLOS219F datasheet and supports deployment in under-hood automotive modules, factory-floor PLCs, and outdoor industrial sensors without derating.
Does the TLC070AIDRG4 require external compensation for unity-gain stability?
No, the TLC070AIDRG4 is internally compensated for unity-gain stability across its full operating range. The datasheet specifies phase margin ≥32° with 50 pF load and confirms stable pulse response in follower configurations - eliminating need for external compensation components in standard gain-of-one applications.
How does the SHDN pin function on the TLC070AIDRG4?
The SHDN pin on the TLC070AIDRG4 is an active-low control: pulling it ≤0.8 V disables the amplifier and reduces supply current to 125 μA per channel; driving it ≥2 V enables normal operation. This behavior is explicitly defined in the Recommended Operating Conditions table and verified in shutdown timing measurements (toff = 2.5 μs at 12 V).
Can the TLC070AIDRG4 drive capacitive loads, and if so, up to how much?
Yes, the TLC070AIDRG4 can drive capacitive loads up to 100 pF while maintaining ≥32° phase margin, as shown in Figure 19 (Phase Margin vs Load Capacitance) of the SLOS219F datasheet. For loads >100 pF, external isolation resistor (e.g., 20–100 Ω) is recommended to preserve stability.
What is the maximum output current specification for the TLC070AIDRG4?
The TLC070AIDRG4 delivers ±55 mA continuous output current - 55 mA sourced (VOH at VDD − 1.5 V) and 55 mA sunk (VOL at 0.5 V), per the Absolute Maximum Ratings and Electrical Characteristics tables in SLOS219F. Short-circuit current exceeds ±100 mA, but continuous operation is limited to ±55 mA for thermal reliability.
