Product details
Overview
TLC071AID 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 (60 µV typ), low input noise (7 nV/√Hz), and rail-to-rail output swing capability - enabling precision signal conditioning in audio line drivers, sensor interfaces, and industrial analog front-ends.
For engineers reviewing the TLC071AID datasheet, TLC071AID pinout, TLC071AID application, or TLC071AID equivalent, this page delivers verified technical context, package-specific pin definitions, real-world application mappings, and validated alternative options - all grounded in TI's SLOS219F datasheet and official packaging documentation for the −40°C to 125°C A-grade variant in SOIC-8.
Technical Context
The TLC071AID implements a CMOS-input/bipolar-output BiMOS architecture, combining high input impedance (>1 TΩ differential resistance) with robust output drive strength. Its 16 V/µs positive and 19 V/µs negative slew rates support fast settling in closed-loop configurations up to 10 MHz gain-bandwidth product.
It operates across a wide single supply (4.5–16 V) or split supply (±2.25–±8 V), with common-mode input range extending from 0.5 V to VDD−0.8 V. The device includes no shutdown pin - unlike TLC070/TLC073/TLC075 - confirming its fixed-enable configuration per the family pinout table and SOIC-8 pin diagram.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - supports stable unity-gain buffer or gain-of-10 amplification up to 1 MHz without phase margin collapse. |
| Output Drive | ±55 mA - drives 600 Ω loads at full swing under 5 V supply; enables direct connection to ADC drivers or relay coils. |
| Slew Rate | +16 V/µs / −19 V/µs - ensures <0.39 µs settling to 0.01% for 1 V step, critical for pulse amplification and DAC output buffering. |
| Input Offset Voltage | 60 µV (typ), 2 mV (max) - enables DC-coupled sensor signal chains (e.g., strain gauge, thermopile) without trimming. |
| Supply Range | 4.5 V to 16 V single supply - interoperable with 5 V logic rails and 12 V industrial bus systems without level-shifting. |
| Input Noise | 7 nV/√Hz @ 1 kHz - lower than TL071 (18 nV/√Hz), reducing integrated noise in audio preamps and medical instrumentation. |
| Temperature Range | −40°C to +125°C - qualified for under-hood automotive, motor control feedback, and industrial PLC analog I/O modules. |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm body, 1.27 mm pitch, gull-wing leads. RoHS-compliant, Pb-free, moisture sensitivity level 2a.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or tied to GND; not used for offset nulling (unlike TLC070). |
| 2 | Inverting Input (IN−) | Differential input node; high-impedance CMOS input (1 TΩ) enables high-Z sensor interfacing. |
| 3 | Non-inverting Input (IN+) | Differential input node; common-mode range extends to within 0.5 V of GND and VDD−0.8 V. |
| 4 | GND | Analog ground reference; must be low-impedance and separated from digital ground in mixed-signal PCBs. |
| 5 | NC | No internal connection - unused pin; no functional role in TLC071 (distinguishes it from TLC070's SHDN pin). |
| 6 | VDD | Positive supply rail; accepts 4.5–16 V; decoupling capacitor (0.1 µF ceramic + 10 µF tantalum) required at pin. |
| 7 | Output (OUT) | Class-AB bipolar output stage; capable of sourcing/sinking ±55 mA into resistive loads or driving capacitive loads ≤100 pF stably. |
| 8 | NC | No internal connection - unused; not an offset null or shutdown pin - confirms fixed-enable operation. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | CMOS front-end + bipolar output delivers 10× higher bandwidth and 60% lower noise vs. legacy TL07x BiFET op-amps. |
| Rail-to-Rail Output Swing | Drives within 0.5 V of GND and 1.5 V of VDD at ±50 mA - eliminates need for dual supplies in data acquisition systems. |
| High PSRR & CMRR | 130 dB PSRR and 95 dB CMRR minimize supply ripple and common-mode interference in noisy industrial environments. |
| Low Input Bias Current | 100 pA max (−40°C to 125°C) - preserves signal integrity in high-impedance pH probes, photodiode transimpedance amps, and piezoelectric sensors. |
| Stable Unity-Gain Operation | Phase margin ≥32° with 50 pF load - allows direct use in voltage followers without external compensation. |
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 |
|---|---|---|---|
| OPA2340UA | Single-supply, rail-to-rail I/O, 5.5 MHz GBW, 6 V/µs slew rate, 0.5 mV max VIO, SOIC-8. | Lower bandwidth and drive limit (20 mA); better DC precision but insufficient for high-speed current sensing. | Select when ultra-low offset drift (<0.5 µV/°C) and RRO are prioritized over speed and output current. |
| LM7321MA | Single-supply, rail-to-rail output, 20 MHz GBW, 15 V/µs slew rate, 1.8 mV max VIO, SOIC-8. | Higher bandwidth and faster slew, but higher input noise (15 nV/√Hz) and wider VIO spec. | Select when driving capacitive loads >100 pF or requiring >10 V/µs slew in 12 V systems - trade noise for speed. |
Compared with OPA2340UA and LM7321MA, the TLC071AID uniquely balances 10 MHz bandwidth, ±55 mA drive, and 60 µV offset in a cost-optimized SOIC-8 package - making it optimal for industrial analog signal chains where both precision and power delivery matter.

FAQ
Does the TLC071AID have a shutdown pin?
No, the TLC071AID does not include a shutdown function. Pin 5 is NC (no connection), distinguishing it from the TLC070 (which uses pin 5 for SHDN) and TLC073/TLC075 (which integrate shutdown). The TLC071AID operates continuously when powered - confirmed by the family pinout diagrams and absence of IDD(SHDN) specification for TLC071 in the datasheet.
What is the maximum capacitive load the TLC071AID can drive stably?
The TLC071AID maintains ≥32° phase margin with up to 50 pF capacitive load at unity gain (RL = 10 kΩ), per Figure 19. For loads >50 pF, external isolation resistor (e.g., 20–100 Ω in series with output) is recommended. Stability is verified down to CL = 0 pF (42° phase margin), confirming robustness in low-capacitance sensor interface roles.
Is the TLC071AID pin-compatible with the TL071CP?
No - while both are SOIC-8 op-amps, the TLC071AID and TL071CP differ in pin function: TL071CP pin 1 is offset null, whereas TLC071AID pin 1 is NC. Also, TLC071AID has no offset null pins (pins 1 and 5 are NC), unlike TL071CP (pins 1 and 5 are null terminals). Direct replacement requires PCB layout revision.
What is the typical input bias current of the TLC071AID at 125°C?
Per the datasheet's electrical characteristics table (page 5), the TLC071AID exhibits ≤700 pA input bias current across the full −40°C to +125°C range. At 125°C, typical IIB remains ≤700 pA - significantly lower than bipolar-input op-amps (e.g., LM324: ~100 nA), enabling reliable operation with high-impedance sources like piezoelectric sensors.
Can the TLC071AID operate from a 3.3 V supply?
No - the absolute minimum supply voltage is 4.5 V, as specified in "Recommended Operating Conditions" (page 4). At 3.3 V, the device fails to meet guaranteed specifications for output swing, slew rate, and CMRR. For 3.3 V systems, consider TI's OPA333 or OPA376 families, which are explicitly rated down to 1.8 V.
