Product details
Overview
TLC072CD from Texas Instruments is a dual-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 TLC072CD datasheet, TLC072CD pinout, TLC072CD application, or TLC072CD equivalent, this page delivers verified specifications, SOIC-8 package layout, real-world use cases in industrial sensing and audio line drivers, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLC072CD integrates a high-impedance CMOS front end with a bipolar output stage, enabling both low input bias current (≤100 pA) and high output current drive (57 mA sourcing / 55 mA sinking). Its 16 V/µs positive slew rate and 19 V/µs negative slew rate support fast settling in active filters and precision buffer stages.
Designed for single-supply systems, it operates across 0°C to 70°C with common-mode input range extending from 0.5 V to VDD − 0.8 V and supports shutdown mode (125 µA/channel) - though the TLC072CD variant lacks dedicated SHDN pins per its SOIC-8 pinout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product enables stable unity-gain buffering up to 10 MHz without phase margin degradation. |
| Output Drive | ±55 mA output current allows direct driving of 600 Ω audio loads or 10 kΩ instrumentation inputs without external buffers. |
| Slew Rate | 16 V/µs (SR+) and 19 V/µs (SR−) ensure <0.39 µs settling to 0.01% for 1 V step at AV = −1 with 10 kΩ/47 pF load. |
| Input Offset Voltage | 60 µV typical (max 1.4 mV) reduces DC error in precision transducer amplification and 16-bit ADC front ends. |
| Supply Range | 4.5 V to 16 V single supply supports battery-powered (5 V) and industrial (12 V) rails without dual-supply complexity. |
| Input Noise | 7 nV/√Hz at 1 kHz enables clean amplification of low-level signals from piezoelectric sensors or microphone capsules. |
| CMRR | 95 dB typical common-mode rejection maintains accuracy in noisy industrial environments with ground offsets. |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm, surface-mount, tape-and-reel compatible (TLC072CDR).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output; capable of ±55 mA drive into resistive or capacitive loads. |
| 2 | IN− A | Inverting input; high-impedance CMOS node (≥1 TΩ) for precision feedback networks. |
| 3 | IN+ A | Non-inverting input; accepts common-mode voltages from 0.5 V to VDD − 0.8 V. |
| 4 | GND | Analog ground reference; must be low-impedance return path for both channels. |
| 5 | IN+ B | Non-inverting input for second channel; independent of Channel A, no crosstalk (−140 dB @ 10 kHz). |
| 6 | IN− B | Inverting input for second channel; matched offset and bias performance to Channel A. |
| 7 | OUT B | Second amplifier output; fully symmetrical AC/DC specs to OUT A. |
| 8 | VDD | Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS architecture | Combines CMOS input stage (low IB, low noise) with bipolar output stage (high IOUT, low Zo) - no external compensation needed. |
| Rail-to-rail output swing | Drives within 0.5 V of GND and within 1.5 V of VDD at full load, maximizing dynamic range in 5 V systems. |
| High PSRR | 100 dB supply rejection minimizes ripple coupling from shared 12 V rails in mixed-signal PCBs. |
| Low THD+N | 0.005% at 1 kHz, 8 VPP, RL = 10 kΩ enables high-fidelity audio line driver implementation. |
| Thermal stability | 1.2 µV/°C offset drift ensures <120 µV total drift over 0°C–70°C, critical for uncalibrated sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel general-purpose op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CD | Lower bandwidth (3 MHz), higher input noise (18 nV/√Hz), no BiMOS output drive (±10 mA). | Acceptable for low-frequency (<100 kHz), low-current (<5 mA) applications like basic comparators or slow integrators. | Select TL072CD only when cost sensitivity outweighs bandwidth, noise, and drive requirements. |
| OPA2340UA | Rail-to-rail input/output, lower offset (125 µV max), lower supply current (750 µA/ch), but limited output drive (25 mA). | Better for ultra-low-voltage (2.7 V) or battery-critical designs where rail-to-rail I/O is mandatory. | Choose OPA2340UA when operating below 4.5 V or requiring true rail-to-rail input swing - not for high-current loads. |
Compared with TL072CD and OPA2340UA, the TLC072CD uniquely balances 10 MHz bandwidth, ±55 mA drive, and 7 nV/√Hz noise - making it optimal for 5–12 V industrial signal chains where fidelity and load capability coexist.

FAQ
What is the maximum supply voltage for the TLC072CD?
The TLC072CD has an absolute maximum supply voltage rating of 17 V, but its recommended operating range is 4.5 V to 16 V. Operating at 16 V maximizes output swing and drive capability, while 4.5 V enables compatibility with Li-ion battery systems. Exceeding 17 V risks permanent damage per TI's Absolute Maximum Ratings table.
Does the TLC072CD support shutdown mode?
No, the TLC072CD does not include shutdown functionality. Shutdown capability is present only in TLC070, TLC073, and TLC075 variants (e.g., TLC073CDGQ), which feature dedicated SHDN pins. The TLC072CD SOIC-8 pinout omits shutdown control - all eight pins are assigned to power, inputs, outputs, and ground for dual-channel operation.
What is the input common-mode voltage range for the TLC072CD at 5 V supply?
At VDD = 5 V, the TLC072CD supports a common-mode input voltage range of 0.5 V to 4.2 V - i.e., from 0.5 V above GND to 0.8 V below VDD. This allows interfacing directly with 0–3.3 V microcontroller DACs or sensors without level-shifting, provided the signal stays within these bounds.
Can the TLC072CD drive a 600 Ω load at 10 VPP?
Yes, the TLC072CD can deliver 10 VPP into 600 Ω with ≤0.012% THD+N at 1 kHz (per datasheet Figure 28). Its 55 mA sinking and 57 mA sourcing capability exceeds the 16.7 mA peak current required, and its 19 V/µs negative slew rate prevents slew-induced distortion during fast transitions.
Is the TLC072CD pin-compatible with the TL072CD?
Yes, the TLC072CD is pin-compatible with the TL072CD in SOIC-8 (D) packages - same pin 1 orientation, identical pin functions (OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, VDD). This enables drop-in replacement to upgrade bandwidth, noise, and output drive without PCB changes.
