Product details
Overview
TLC071ID 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 rail-to-rail output swing in audio preamplifier and sensor signal conditioning circuits.
For engineers reviewing the TLC071ID datasheet, TLC071ID pinout, TLC071ID application, or TLC071ID equivalent, this page delivers verified electrical parameters, industrial-temperature-rated package details (SOIC-8), shutdown functionality, and real-world design context for precision analog signal paths in automotive and industrial systems.
Technical Context
The TLC071ID uses TI's patented LBC3 BiCMOS process, combining a CMOS front end for high input impedance and low noise with a bipolar output stage for high current drive. Its architecture supports stable unity-gain operation with phase margin ≥32° at 50 pF load and gain-bandwidth product of 10 MHz across supply voltages.
It integrates an active shutdown mode (125 µA/channel) controlled by a logic-level SHDN pin, enabling power management in battery-powered instrumentation. Input common-mode range extends from 0.5 V to VDD − 0.8 V, supporting direct interfacing with microcontroller ADCs and DACs operating on the same rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and ultrasonic frequencies without gain roll-off. |
| Output Drive | ±55 mA - drives heavy loads such as 600 Ω audio lines or multiple parallel inputs without external buffers. |
| Slew Rate | +16 V/µs / −19 V/µs - preserves fast transient fidelity in pulse and video applications with minimal distortion. |
| Input Offset Voltage | 60 µV typical - reduces DC error in precision transducer interfaces and closed-loop control feedback paths. |
| Supply Range | 4.5 V to 16 V single supply - eliminates need for dual-rail supplies in industrial sensors and automotive ECUs. |
| Shutdown Current | 125 µA per channel - extends battery life in portable test equipment during idle periods. |
| Input Noise | 7 nV/√Hz at 1 kHz - maintains signal integrity in low-level sensor amplification (e.g., thermocouples, strain gauges). |
Pinout & Package
TLC071ID is packaged in an 8-pin SOIC (D package) with exposed pad thermal enhancement, rated for −40°C to +125°C operation. Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplified output node capable of sourcing/sinking ±55 mA into resistive or capacitive loads. |
| 2 | IN− | Inverting input with 1000 GΩ differential resistance; connects to feedback network in standard configurations. |
| 3 | IN+ | Non-inverting input with 1000 GΩ differential resistance; accepts high-impedance sensor or reference signals. |
| 4 | GND | Analog ground reference for single-supply biasing; must be low-impedance and separated from digital ground. |
| 5 | NC | No internal connection - left unconnected; not used for signal or power routing. |
| 6 | VDD | Positive supply rail (4.5–16 V); powers both input and output stages; requires local 0.1 µF bypass capacitor. |
| 7 | SHDN | Active-high shutdown control (VIH ≥ 2 V); reduces IDD to 125 µA when asserted, disabling output and bias currents. |
| 8 | NULL | No internal connection - electrically isolated; no routing required. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (low IB, low noise) with bipolar output stage (high IOUT, low Zo) for optimal AC/DC performance. |
| Rail-to-Rail Output Swing | Drives within 0.5 V of GND and within 1.5 V of VDD under 50 mA load - maximizes dynamic range in single-supply systems. |
| Industrial Temperature Range | Specified from −40°C to +125°C - qualified for under-hood automotive and factory-floor industrial environments. |
| Low THD+N | 0.005% at 1 kHz, AV = 10, VO(PP) = 8 V - meets fidelity requirements for audio line drivers and data acquisition front ends. |
| High PSRR & CMRR | 100 dB PSRR and 100 dB CMRR - rejects supply ripple and common-mode interference in noisy ECU or motor-control PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLC071ID's 1.2 µV/°C; lower quiescent current (17 µA) but lower output drive (25 mA). | Better for ultra-low-drift DC-coupled systems (e.g., medical sensors); unsuitable for high-current loads like audio drivers. | Select OPA2333AIDR only when long-term DC stability outweighs output current needs. |
| LM7321IMX/NOPB | Higher slew rate (20 V/µs), wider supply range (2.7–36 V), but higher input noise (15 nV/√Hz) and no shutdown pin. | Preferred for wide-input-voltage industrial sensors; lacks power-gating capability needed in portable instruments. | Choose LM7321IMX/NOPB when extended supply range and speed are critical, and shutdown is managed externally. |
Compared with OPA2333AIDR and LM7321IMX/NOPB, the TLC071ID uniquely balances high output drive, industrial temperature rating, integrated shutdown, and low noise-making it optimal for cost-sensitive, high-fidelity analog signal chains where power efficiency and robustness coexist.

FAQ
What is the operating temperature range of the TLC071ID?
The TLC071ID is rated for operation from −40°C to +125°C, meeting industrial and automotive under-hood requirements. This specification is confirmed in the "Recommended Operating Conditions" table of the SLOS219F datasheet, where the "I-suffix" designation explicitly defines this extended range.
Does the TLC071ID support rail-to-rail input or output?
The TLC071ID supports rail-to-rail output swing (within 0.5 V of GND and 1.5 V of VDD at full load) but does not feature rail-to-rail input. Its common-mode input voltage range is specified as 0.5 V to VDD − 0.8 V, meaning it cannot accept signals at the negative rail (GND) or within 0.8 V of VDD.
What is the purpose of the SHDN pin on the TLC071ID?
The SHDN pin on the TLC071ID is an active-high logic input that places the amplifier into ultralow-power shutdown mode (125 µA per channel) when driven ≥2 V. When deasserted (<0.8 V), normal operation resumes with typical turn-on time of 0.47 µs at VDD = 12 V - enabling precise power gating in portable instrumentation.
Can the TLC071ID drive a 600 Ω load at full output swing?
Yes, the TLC071ID can drive a 600 Ω load while maintaining full output swing: at VDD = 12 V, it delivers VOH ≥ 10.3 V and VOL ≤ 0.65 V under 50 mA load (per datasheet Figure 7 and 8). This satisfies professional audio line-driving standards and eliminates need for external buffer stages.
How does the TLC071ID compare to the TL071 in terms of bandwidth and noise?
The TLC071ID offers 10 MHz bandwidth - a 300% increase over the TL071's 3 MHz - and 7 nV/√Hz input voltage noise - a 60% improvement over TL071's 18 nV/√Hz. These enhancements stem from its BiMOS LBC3 process, making it a direct performance upgrade for single-supply designs replacing TL071-based circuits.
