Product details
Overview
TLC070AIP 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 (max 1400 µV), low input noise (7 nV/√Hz at 1 kHz), and integrated shutdown functionality - enabling precision signal conditioning in audio line drivers, industrial sensor interfaces, and automotive body control modules.
For engineers reviewing the TLC070AIP datasheet, TLC070AIP pinout, TLC070AIP application, or TLC070AIP 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 TLC070AIP 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 positive slew rate, 10 MHz GBW) and robust DC accuracy (1.2 µV/°C input offset drift).
It operates across −40°C to +125°C with rail-to-rail input common-mode range (0.5 V to VDD−0.8 V) and supports active shutdown (125 µA/channel quiescent current), making it suitable for thermally demanding, power-sensitive systems requiring fast settling (0.17 µs to 0.1%) and low THD+N (0.005% at 1 kHz, AV=10, VDD=12 V).
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 without phase margin collapse. |
| Slew Rate | +16 V/µs / −19 V/µs - enables clean reproduction of fast transient signals (e.g., 1-V step in <0.2 µs) without slewing distortion in audio or pulse-amplifier stages. |
| Output Drive | ±55 mA continuous - drives heavy loads including 600-Ω audio lines, capacitive DAC buffers, or relay drivers without external boost circuitry. |
| Input Offset Voltage | Max 1400 µV over full temperature range - ensures sub-mV DC error in precision transducer amplifiers and low-gain instrumentation paths. |
| Supply Range | 4.5 V to 16 V single supply - eliminates dual-rail complexity in battery-powered (e.g., 2S Li-ion) and industrial 12-V systems. |
| Shutdown Current | 125 µA/channel - reduces system standby power by >93% vs active mode (1.9 mA), critical for always-on sensor nodes. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and low-level sensor signal chains where thermal noise dominates. |
Pinout & Package
Package: 8-pin PDIP (Plastic Dual In-line Package), 0.3-inch width, through-hole mounting. Compatible with standard DIP sockets and wave-solder processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - electrically isolated; may be left unconnected or grounded per layout best practice. |
| 2 | IN− | Inverting input - accepts feedback network; high impedance (>1 TΩ differential) minimizes loading on preceding stage. |
| 3 | IN+ | Non-inverting input - high common-mode rejection (80–100 dB) enables accurate sensing in noisy environments. |
| 4 | GND | Analog ground reference - must be tied to low-impedance system ground plane to maintain PSRR (≥80 dB) and minimize offset drift. |
| 5 | SHDN | Active-high shutdown control - driven ≥2 V to enable, ≤0.8 V to disable; transitions in <2.5 µs (toff) and <0.47 µs (ton). |
| 6 | VDD | Positive supply rail - supports 4.5–16 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability. |
| 7 | OUT | Amplified output - capable of sourcing/sinking ±55 mA into resistive or moderately capacitive loads (≤100 pF). |
| 8 | NULL | No internal connection - identical to Pin 1; no routing or soldering required. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS architecture | Combines CMOS input stage (ultra-low bias current: 100 pA max) with bipolar output (high drive: ±55 mA), eliminating trade-offs between input precision and output strength. |
| Wide supply range | Operates from 4.5 V (2×Li-ion) to 16 V (industrial 12-V bus with ripple), reducing need for LDOs in multi-voltage systems. |
| Shutdown mode | Reduces total supply current to 125 µA/channel - enables rapid power cycling in battery-operated data loggers without sacrificing wake-up speed (<0.5 µs). |
| High slew rate asymmetry | Negative slew rate (19 V/µs) exceeds positive (16 V/µs), improving fidelity of asymmetric waveforms like PWM-derived analog signals. |
| Low THD+N | 0.005% at 1 kHz (VDD = 12 V, RL = 10 kΩ, AV = 10) - meets Class-D amplifier feedback and high-fidelity line-driver requirements. |
Applications
| Audio Line Driver | Industrial Sensor Signal Conditioning |

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), lower output drive (±10 mA), no shutdown, higher input offset (6 mV max), same 8-pin PDIP package. | Not suitable for high-speed or high-current applications; lacks power management for battery systems. | Select TL071CP only when cost sensitivity outweighs performance needs and shutdown is unnecessary. |
| OPA1671AIP | Higher precision (50 µV offset), lower noise (4.5 nV/√Hz), rail-to-rail output, but lower output drive (±35 mA) and no shutdown. | Better for ultra-low-noise audio preamps; insufficient for driving 600-Ω lines at full swing or relay coils. | Choose OPA1671AIP when SNR and DC accuracy are paramount and load current remains <35 mA. |
Compared with TL071CP, TLC070AIP delivers 3.3× higher bandwidth and 5.5× greater output current, enabling faster response and direct drive of heavier loads; versus OPA1671AIP, it trades some noise/offset performance for robust output drive and integrated shutdown - making it optimal for mixed-signal industrial actuators and power-aware analog subsystems.

FAQ
What is the operating temperature range for the TLC070AIP?
The TLC070AIP is rated for −40°C to +125°C, matching the "I" temperature suffix. This extended industrial range allows deployment in under-hood automotive sensors, motor control feedback loops, and outdoor industrial equipment without derating or thermal protection circuitry. The TLC070AIP maintains specified performance-including input offset voltage, slew rate, and output drive-across this full range.
Does the TLC070AIP support rail-to-rail input operation?
Yes, the TLC070AIP supports rail-to-rail input common-mode voltage from 0.5 V above GND to VDD−0.8 V. At VDD = 5 V, this spans 0.5 V to 4.2 V; at VDD = 12 V, it covers 0.5 V to 11.2 V. This enables direct interfacing with SAR ADCs, DACs, and microcontroller I/O pins without level-shifting, preserving dynamic range in single-supply systems.
How does the shutdown feature of the TLC070AIP function?
The TLC070AIP's SHDN pin (Pin 5) is active-high: applying ≥2 V enables normal operation; ≤0.8 V places the device in ultralow-power shutdown (125 µA/channel). Turn-on time is 0.47 µs and turn-off time is 2.5 µs at 25°C. This allows rapid power gating in portable instruments and sensor nodes without compromising responsiveness.
Can the TLC070AIP drive a 600-Ω load at 12 V supply?
Yes - the TLC070AIP delivers ±55 mA continuously, enabling ±6.6 V output swing into 600 Ω (11 Vpp) at VDD = 12 V. Measured THD+N is 0.005% at 1 kHz under these conditions. Its high slew rate (16–19 V/µs) prevents distortion on fast transients, making it suitable for professional audio line drivers without external buffers.
What is the typical input bias current of the TLC070AIP?
The TLC070AIP exhibits typical input bias current of 1.5 pA at 25°C (max 100 pA over full temperature range), enabled by its CMOS input stage. This ultra-low bias current minimizes voltage errors across high-impedance feedback networks (e.g., >1 MΩ) and prevents significant DC error in photodiode transimpedance amplifiers or high-Z sensor interfaces.
