Product details
Overview
TLC070IDR 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 (60 µV typ), low input noise (7 nV/√Hz), and integrated shutdown control - enabling precision signal conditioning in audio line drivers, sensor front-ends, and industrial analog I/O modules.
For engineers reviewing the TLC070IDR datasheet, TLC070IDR pinout, TLC070IDR application, or TLC070IDR equivalent, this page delivers verified electrical specs, validated pin functions, real-world use cases in single-supply systems, and confirmed alternative options with documented functional trade-offs - all aligned to TI's SLOS219F revision December 2011 production data.
Technical Context
The TLC070IDR employs TI's patented LBC3 BiCMOS process, combining a CMOS front-end for high input impedance (>1 GΩ) and low input bias current (<100 pA) with a bipolar output stage delivering ±55 mA drive into resistive loads. Its rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and fast slew rates (16 V/µs positive, 19 V/µs negative) support dynamic signal integrity in active filters and buffer stages.
Integrated shutdown logic (active-low SHDN pin) reduces supply current to 125 µA/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, meeting extended industrial temperature requirements without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - supports stable unity-gain buffers and 2nd-order active filters up to ~1.6 MHz. |
| Output Drive | ±55 mA continuous output current - drives 600 Ω audio loads or multiple CMOS inputs without external buffering. |
| Slew Rate | +16 V/µs / −19 V/µs - preserves fidelity of 1–2 VPP signals above 1 MHz in pulse and video applications. |
| Input Offset Voltage | 60 µV typical (25°C), ≤2 mV max over full temperature range - enables DC-coupled sensor amplification with <0.01% error. |
| Supply Range | 4.5 V to 16 V single supply - compatible with 5 V, 12 V, and 15 V industrial rails without split-supply circuitry. |
| Shutdown Current | 125 µA/channel - reduces system standby power by >93% vs active mode (1.9 mA), critical for battery-backed instrumentation. |
| Input Noise | 7 nV/√Hz at 1 kHz - maintains SNR >90 dB in 20 kHz audio paths with 10 kΩ source impedances. |
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); requires matched trace routing to minimize offset drift. |
| 3 | IN+ | Non-inverting input - same high-impedance interface as IN−; common-mode range extends to within 0.5 V of GND. |
| 4 | GND | Analog ground reference - connects to PCB ground plane under PowerPAD for optimal thermal and noise performance. |
| 5 | SHDN | Active-low shutdown control - pulls supply current to 125 µA when ≤0.8 V; must be pulled high (>2 V) for normal operation. |
| 6 | VDD | Positive supply rail - accepts 4.5–16 V; decoupling capacitor (0.1 µF ceramic + 10 µF tantalum) required within 5 mm. |
| 7 | OUT | Amplifier output - capable of sourcing/sinking ±55 mA; phase margin ≥32° with 50 pF capacitive load. |
| 8 | NULL | No internal connection - unused pin; no routing or soldering required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Lower bandwidth (5.5 MHz), lower output drive (±30 mA), no shutdown pin, rail-to-rail output only. | Better for ultra-low-power (750 µA) battery-operated devices where full rail-to-rail input and shutdown are not required. | Select OPA2340UA when supply current <1 mA is mandatory and output swing to rails is critical; avoid if >50 mA drive or shutdown control needed. |
| TLV2771CDR | Higher quiescent current (1.3 mA), lower slew rate (10.5 V/µs), no shutdown, wider temp range (−40°C to 125°C). | Optimized for cost-sensitive industrial controls where moderate speed and robustness outweigh low-noise needs. | Select TLV2771CDR for non-critical signal paths with 12 V supplies and no power cycling; avoid for audio or fast-settling applications. |
Compared with OPA2340UA and TLV2771CDR, the TLC070IDR uniquely balances 10 MHz bandwidth, ±55 mA drive, and shutdown capability in an SOIC-8 package - making it the only option among the three suitable for high-fidelity, power-gated, single-supply analog stages.

FAQ
What is the maximum output current capability of the TLC070IDR?
The TLC070IDR delivers ±55 mA continuous output current - 57 mA sourcing (VOH at VDD−1.5 V) and 55 mA sinking (VOL at 0.5 V) - verified per TI's SLOS219F datasheet at 25°C and VDD = 5 V or 12 V. This enables direct driving of 600 Ω audio loads, LED strings, or multiple logic inputs without external buffers.
Does the TLC070IDR support rail-to-rail input operation?
Yes, the TLC070IDR supports rail-to-rail input common-mode voltage from 0.5 V to VDD−0.8 V, allowing direct interfacing with DAC outputs, ADC references, and unipolar sensors operating near GND or VDD. Input offset voltage remains stable across this range, with typical VIO = 60 µV at 25°C.
How does the shutdown feature of the TLC070IDR function?
The TLC070IDR's SHDN pin is active-low: pulling it ≤0.8 V reduces supply current to 125 µA/channel, while >2 V enables normal operation (IDD = 1.9 mA). Turn-on time is 0.47 µs and turn-off time is 2.5 µs at VDD = 12 V - enabling rapid power cycling in multi-channel sensor systems.
What is the gain-bandwidth product and stability behavior of the TLC070IDR?
The TLC070IDR has a guaranteed 10 MHz gain-bandwidth product and is unity-gain stable. Phase margin is ≥32° with 50 pF capacitive load and ≥42° with no load (RL = 10 kΩ), ensuring robust stability in buffer, active filter, and gain configurations without external compensation.
Is the TLC070IDR pin-compatible with legacy TL071 op-amps?
No - the TLC070IDR is not pin-compatible with TL071. While both are SOIC-8 single op-amps, TLC070IDR uses pins 1 and 8 as NULL (no connect), whereas TL071 uses pin 1 for offset null and pin 5 for offset null. Direct replacement requires PCB modification to accommodate the different pin functions.
