Product details
Overview
TLC071CDG4 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 capability - enabling precision signal conditioning in audio line drivers, sensor front-ends, and industrial analog I/O modules.
For engineers reviewing the TLC071CDG4 datasheet, TLC071CDG4 pinout, TLC071CDG4 application, or TLC071CDG4 equivalent, this device is selected where high slew rate (16 V/µs), robust output drive into heavy loads, and stable performance across −40°C to 125°C are required - especially in space-constrained designs using SOIC-8 packaging.
Technical Context
The TLC071CDG4 employs TI's patented LBC3 BiCMOS process, combining a high-impedance CMOS input stage with a bipolar output stage to deliver both low noise (7 nV/√Hz) and high current drive (57 mA sourcing / 55 mA sinking). Its architecture supports stable unity-gain operation with phase margin ≥32° at 50 pF load and exhibits excellent PSRR (100 dB) and CMRR (95 dB) over frequency.
Unlike legacy TL07x predecessors, the TLC071CDG4 achieves 3× higher bandwidth (10 MHz vs. ~3 MHz), 60% lower voltage noise, and 4× reduced input offset voltage - while maintaining compatibility with standard op-amp feedback topologies and supporting shutdown mode (125 µA/channel) for power-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable closed-loop operation up to 100 kHz at AV = 100 without compensation. |
| Slew Rate | +16 V/µs / −19 V/µs - supports fast settling of large-signal transients in active filters and DAC buffers. |
| Output Drive | ±55 mA continuous - drives 600 Ω loads directly, eliminating external buffer stages in line-driver circuits. |
| Input Offset Voltage | 60 µV typical (25°C) - reduces DC error in precision instrumentation amplifiers and sensor signal chains. |
| Supply Range | 4.5 V to 16 V single supply - operates from 5 V logic rails or 12 V industrial buses without dual supplies. |
| Shutdown Current | 125 µA per channel - enables low-power sleep modes in battery-backed data acquisition systems. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level audio and medical sensor amplification paths. |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - left unconnected; no routing or thermal tie required. |
| 2 | Inverting Input (IN−) | Differential input node for feedback networks; high impedance (>1 TΩ) minimizes loading on source. |
| 3 | Non-inverting Input (IN+) | Reference input for follower or summing configurations; common-mode range extends to 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 | SHDN | Active-high shutdown control (VIH ≥ 2 V) - disables amplifier and reduces IDD to 125 µA; compatible with 3.3 V/5 V logic. |
| 6 | VDD | Positive supply rail - accepts 4.5 V to 16 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm. |
| 7 | OUT | Class-AB output stage - delivers ±55 mA into resistive loads; capable of driving capacitive loads ≤100 pF stably. |
| 8 | NC | No internal connection - electrically isolated; may be used as thermal pad anchor if grounded externally. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input (low IB, low noise) with bipolar output (high drive, low Zo) - eliminates trade-off between precision and power delivery. |
| Rail-to-Rail Output Swing | Swings within 0.5 V of GND and 1.5 V of VDD at 50 mA - maximizes dynamic range in single-supply data converters and ADC drivers. |
| Wide Common-Mode Range | 0.5 V to VDD−0.8 V - supports direct sensing of signals referenced to GND or mid-supply in industrial 4–20 mA receivers. |
| Integrated Shutdown Mode | Reduces quiescent current to 125 µA/channel - enables rapid power cycling in portable test equipment and IoT edge nodes. |
| Stable Unity-Gain Operation | Phase margin ≥32° with 50 pF load - eliminates need for external compensation in most buffer and gain-of-one applications. |

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, lower bandwidth (5.5 MHz), lower output drive (30 mA), higher supply current (800 µA). | Better for ultra-low-power, low-frequency (<100 kHz) precision apps; unsuitable for 600 Ω line driving or fast settling. | Select when power budget <1 mA/channel is critical and bandwidth ≤5 MHz suffices. |
| LM7321MA | Higher slew rate (20 V/µs), wider supply range (2.7–36 V), but higher input offset (1.8 mV max) and noise (15 nV/√Hz). | Better for high-voltage industrial sensors; less suitable for low-noise audio or µV-level DC measurements. | Select when >16 V operation or faster transient response is needed, and offset/noise specs are relaxed. |
Compared with OPA2340UA and LM7321MA, the TLC071CDG4 uniquely balances 10 MHz bandwidth, ±55 mA drive, and 60 µV offset in an SOIC-8 package - making it optimal for cost-sensitive, performance-critical single-supply analog signal paths where both speed and precision matter.

FAQ
What is the maximum capacitive load the TLC071CDG4 can drive without oscillation?
The TLC071CDG4 maintains stability with capacitive loads up to 100 pF when configured as a unity-gain buffer, as verified by phase margin ≥32° at 50 pF and ≥25° at 100 pF (per Figure 19–20). For loads >100 pF, a series isolation resistor (20–100 Ω) between OUT and the capacitor is recommended to preserve stability in driving cables or ADC input capacitance.
Does the TLC071CDG4 support true rail-to-rail input operation?
No - the TLC071CDG4 has a common-mode input voltage range of 0.5 V to VDD−0.8 V, meaning it does not accept inputs at GND or VDD. However, its output swings within 0.5 V of GND and 1.5 V of VDD at full load, providing near rail-to-rail output capability essential for maximizing dynamic range in single-supply systems.
How does the shutdown feature of the TLC071CDG4 behave during power-up?
The TLC071CDG4 enters normal operation at power-on because SHDN defaults to inactive (high-impedance pull-down not integrated). To ensure defined startup behavior, tie SHDN to VDD via a 10 kΩ resistor or actively drive it high after VDD stabilizes. During shutdown, output goes high-impedance and supply current drops to 125 µA/channel - no output clamping or leakage occurs.
Can the TLC071CDG4 replace the TL071CP in existing designs?
Yes - the TLC071CDG4 is pin-compatible with TL071CP in SOIC-8 (D) package and offers superior performance: 3× higher bandwidth (10 MHz vs. 3 MHz), 60% lower noise (7 vs. 18 nV/√Hz), and 4× lower input offset (60 µV vs. 250 µV typ). No layout changes are required, but verify that the improved slew rate and output drive do not induce unintended ringing in high-Z feedback networks.
What is the thermal resistance (θJA) of the TLC071CDG4 in SOIC-8 package?
The TLC071CDG4 in SOIC-8 (D) package has a junction-to-ambient thermal resistance (θJA) of 176°C/W under standard JEDEC 2-layer board conditions. With 25°C ambient and 1.9 mA supply current (9.5 mW dissipation), junction temperature rise is ~1.7°C - well within safe limits. For continuous 55 mA output, power dissipation increases to ~300 mW, raising junction temperature by ~53°C above ambient.
