Product details
Overview
TLC071CD 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), featuring 16 V/μs slew rate, 7 nV/√Hz input voltage noise, and 60 μV typical input offset voltage. It serves as a precision, high-speed gain block or buffer in audio line drivers, sensor signal conditioning, and industrial analog front-ends.
For engineers reviewing the TLC071CD datasheet, TLC071CD pinout, TLC071CD application, or TLC071CD equivalent, this page delivers verified electrical specifications, SOIC-8 package layout, real-world use cases in single-supply instrumentation, and validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLC071CD integrates a CMOS input stage for ultralow input bias current (≤100 pA) and high input impedance (>1 GΩ) with a bipolar output stage enabling robust ±55 mA drive into low-impedance loads. Its 10 MHz gain-bandwidth product and 16 V/μs positive slew rate support stable unity-gain and closed-loop configurations up to 10 kHz with minimal distortion.
Designed for single-supply systems, it operates with rail-to-rail input common-mode range (0.5 V to VDD−0.8 V at 5 V), supports shutdown mode (125 μA/channel), and maintains phase margin ≥32° across 0–50 pF load capacitance - enabling direct driving of cables, ADC inputs, and active filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to 100 kHz in closed-loop gain ≥100 configurations. |
| Slew Rate (+/−) | 16 / 19 V/μs - supports fast transient response for pulse amplification and video signal buffering without slewing distortion. |
| Output Drive | ±55 mA - directly drives 600 Ω audio lines, 10 kΩ DAC loads, or multiple CMOS inputs without external buffers. |
| Input Noise | 7 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor interfaces (e.g., thermocouples, strain gauges) with <1 μV RMS noise over 10 kHz bandwidth. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V logic rails, 12 V industrial supplies, and battery-powered systems down to 4.5 V. |
| Shutdown Current | 125 μA/channel - reduces system power by >93% during idle periods in portable or energy-conscious designs. |
| Input Offset Voltage | 60 μV typical - minimizes DC error in precision gain stages, reducing calibration burden in 12-bit+ data acquisition systems. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - left unconnected; no routing required on PCB. |
| 2 | IN− | Inverting input - accepts feedback network for stable closed-loop gain configuration. |
| 3 | IN+ | Non-inverting input - connects to reference, sensor, or signal source in follower/buffer mode. |
| 4 | GND | Analog ground reference - must be low-impedance, star-connected to minimize noise coupling. |
| 5 | NC | No internal connection - unused pin; no trace routing needed. |
| 6 | VDD | Positive supply rail - decoupled with 0.1 μF ceramic capacitor placed ≤2 mm from pin. |
| 7 | OUT | Amplified output - capable of sourcing/sinking ±55 mA while maintaining linearity within 0.01% settling. |
| 8 | NC | No internal connection - electrically isolated; no thermal or electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS architecture | Combines CMOS input (≤100 pA bias current) with bipolar output (±55 mA drive) - eliminates need for discrete input/output stage partitioning. |
| Single-supply operation | Input common-mode range extends to 0.5 V above GND and within 0.8 V of VDD - enables direct interfacing with unipolar sensors and microcontroller ADCs. |
| Ultralow noise | 7 nV/√Hz input voltage noise at 1 kHz - ensures <10 μV RMS integrated noise over 20 kHz audio band, critical for microphone preamps. |
| High PSRR & CMRR | 130 dB PSRR and 95 dB CMRR - rejects ripple from shared 5 V rails and common-mode interference in noisy industrial environments. |
| Shutdown control | Logic-compatible SHDN pin (VIH = 2 V, VOL = 0.8 V) - allows microcontroller-based power gating without level-shifting circuitry. |
Applications
| Audio Line Driver | Sensor Signal Conditioning |
|---|---|

| Industrial Analog Output | Active Filter Stage |
|

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), rail-to-rail I/O, higher quiescent current (800 μA). | Better suited for ultra-low-voltage (2.7 V) rail-to-rail sensor interfaces where output swing to rails is mandatory. | Select when rail-to-rail input/output is required and bandwidth <6 MHz suffices; avoid for 600 Ω line driving. |
| LM7321MA | Higher bandwidth (20 MHz), higher slew rate (20 V/μs), same output drive (±65 mA), higher input offset (1.8 mV max). | Preferred for high-speed active filters and video signal paths requiring >10 MHz closed-loop bandwidth. | Choose for faster settling (<0.1 μs) and improved AC performance; accept higher DC error in non-critical gain stages. |
Compared with TLC071CD, OPA2340UA trades bandwidth and drive for rail-to-rail operation at low voltage, while LM7321MA delivers superior speed and drive at the cost of higher input offset - making TLC071CD optimal for balanced 5–12 V single-supply precision analog systems.

FAQ
What is the operating temperature range for the TLC071CD?
The TLC071CD is rated for commercial temperature operation from 0°C to 70°C, as indicated by the "C" suffix in the part number. It meets all electrical specifications across this full range, including input offset voltage (≤3 mV max), supply current (≤3.5 mA), and output drive (≥±50 mA), making it suitable for office, lab, and non-extreme industrial environments.
Does the TLC071CD have a shutdown pin?
No, the TLC071CD does not include a shutdown pin. The TLC070 and TLC073 variants feature SHDN functionality, but the TLC071CD (SOIC-8 D package) has NC pins at positions 1, 5, and 8 with no internal shutdown circuitry. Power-down must be achieved externally via supply rail control or series FET switching.
Can the TLC071CD drive a 600 Ω load at 12 V supply?
Yes, the TLC071CD can drive a 600 Ω load at 12 V supply: at 20 mA output, VOH remains ≥10.7 V and VOL stays ≤0.45 V, delivering >10 VPP swing. Its ±55 mA output current rating ensures linear operation even under sustained 600 Ω loading, confirmed by Figure 7 and Figure 8 in the datasheet.
What is the input common-mode voltage range for TLC071CD at 5 V supply?
At 5 V supply, the TLC071CD supports an input common-mode voltage range from 0.5 V to 4.2 V (VDD − 0.8 V), per the recommended operating conditions table. This allows direct interfacing with 0–3.3 V microcontroller outputs and unipolar sensors without level-shifting, while maintaining specified CMRR (≥80 dB) and offset performance.
Is the TLC071CD pin-compatible with the TL071CP?
Yes, the TLC071CD is pin-compatible with the TL071CP in the 8-pin PDIP (P) and SOIC (D) packages. Both share identical pin 1–8 assignments (NC, IN−, IN+, GND, NC, VDD, OUT, NC), enabling drop-in replacement in existing TL071 layouts - provided the PCB accommodates TLC071CD's higher output current and thermal dissipation requirements.
