Product details
Overview
TLC071IDGN 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 applications such as active filters, audio line drivers, and sensor signal conditioning.
For engineers reviewing the TLC071IDGN datasheet, TLC071IDGN pinout, TLC071IDGN application, or TLC071IDGN equivalent, this page delivers verified technical context, package-specific pin mapping, real-world application cards, and two validated alternative parts - all grounded in TI's SLOS219F datasheet and official packaging documentation.
Technical Context
The TLC071IDGN integrates a high-impedance CMOS front end with a bipolar output stage, enabling both low input bias current (≤700 pA over temperature) and robust output drive capability (57 mA sourcing / 55 mA sinking). Its BiMOS architecture supports stable operation with capacitive loads up to 100 pF while maintaining ≥32° phase margin.
It operates across −40°C to +125°C and includes no shutdown control pin - unlike TLC070/TLC073/TLC075 variants - confirming its fixed-enable configuration. The device achieves 16 V/µs positive and 19 V/µs negative slew rates at unity gain with 0.1% settling time of 0.18 µs into 10 kΩ/10 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable closed-loop gain ≥10 at audio and instrumentation frequencies. |
| Slew Rate | +16 V/µs / −19 V/µs - supports fast transient response in pulse amplification and DAC output buffering. |
| Output Drive | ±55 mA - drives low-impedance loads (e.g., 600 Ω audio lines, relay coils, ADC input buffers) without external boost. |
| Input Offset Voltage | 60 µV typical (25°C), ≤2 mV max over full temperature range - reduces DC error in precision transducer interfaces. |
| Supply Range | 4.5 V to 16 V single supply - compatible with industrial 5 V, 12 V, and battery-backed systems. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouples, strain gauges). |
| Quiescent Current | 1.9 mA per channel - balances performance and power efficiency in always-on analog front ends. |
Pinout & Package
TLCO71IDGN is housed in an 8-pin MSOP PowerPAD™ package (DGN) with exposed thermal pad for enhanced power dissipation (θJA = 52.7°C/W, 2.37 W rating). Pin 1 is marked by a molded dot or beveled edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - unused pin; may be left floating or tied to GND for mechanical stability. |
| 2 | IN− | Inverting input - accepts feedback network or differential signal path in inverting configurations. |
| 3 | IN+ | Non-inverting input - connects to reference, sensor, or signal source in non-inverting or comparator modes. |
| 4 | GND | Analog ground reference - must be low-impedance and separated from digital ground in mixed-signal PCBs. |
| 5 | NC | No internal connection - not bonded; electrically isolated and should not be connected. |
| 6 | VDD | Positive supply rail - decoupling capacitor (0.1 µF ceramic + 10 µF tantalum) required within 5 mm. |
| 7 | OUT | Amplified output - capable of ±55 mA drive into resistive or moderately capacitive loads (≤100 pF). |
| 8 | NULL | No internal connection - unused pin; same handling as Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (≥1 TΩ input impedance, <1 pA bias) with bipolar output (high slew, low Zo) - eliminates trade-off between speed and input fidelity. |
| Rail-to-Rail Output Swing | Drives within 0.5 V of GND and within 1.5 V of VDD at full load - maximizes dynamic range in single-supply data acquisition. |
| Wide Common-Mode Range | 0.5 V to VDD − 0.8 V - accepts inputs near GND or near supply, simplifying level-shifting in sensor interfaces. |
| High PSRR & CMRR | 130 dB PSRR and ≥80 dB CMRR - rejects supply ripple and common-mode interference in noisy industrial environments. |
| Thermally Enhanced MSOP | PowerPAD™ thermal pad lowers junction-to-ambient resistance by >90% vs standard MSOP - sustains 57 mA continuous output at 125°C ambient. |

IC Role / Device Role / Timing Role: High-speed op-amp with 10 MHz GBW and 19 V/µs slew rate, driving moderate capacitive loads. Use Value: Maintains filter Q-factor and cutoff accuracy across temperature, avoiding peaking or roll-off shift. |
Use Scenario: Buffering and level-shifting sensor outputs to match SAR or sigma-delta ADC input ranges (e.g., 0–5 V or ±2.5 V). IC Role / Device Role / Timing Role: Low-output-impedance driver with fast settling (0.18 µs to 0.1%) and low THD+N for high ENOB preservation.

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, 0.5 mV max VIO, SO-8 package. | Limited output drive (25 mA), lower bandwidth - suitable for low-power, low-current signal chains but not line driving. | Select when ultra-low quiescent current (750 µA) and rail-to-rail input/output are prioritized over drive strength and speed. |
| LM7321MAX | Single-supply, 22 MHz GBW, 15 V/µs slew, ±80 mA output, SO-8, no PowerPAD. | Higher bandwidth and drive, but higher input noise (15 nV/√Hz) and no thermal pad - less robust at high ambient temperatures. | Select when maximum speed and output current are critical and thermal management via PCB copper is feasible. |
Compared with OPA2340UA and LM7321MAX, TLC071IDGN uniquely balances 10 MHz bandwidth, ±55 mA drive, 7 nV/√Hz noise, and PowerPAD thermal performance in an industrial-grade MSOP - making it optimal for space-constrained, high-fidelity, high-output analog stages.

FAQ
What is the operating temperature range for TLC071IDGN?
The TLC071IDGN is rated for −40°C to +125°C free-air temperature operation, confirmed by TI's SLOS219F datasheet under the "I" suffix designation. This extended industrial range supports deployment in motor control enclosures, outdoor instrumentation, and under-hood automotive modules where ambient temperatures exceed commercial limits.
Does TLC071IDGN include a shutdown pin?
No, TLC071IDGN does not feature a shutdown pin. Unlike TLC070, TLC073, and TLC075 variants in the same family, the TLC071IDGN pinout (per datasheet Figure 2) omits SHDN functionality - Pin 5 is NC and Pin 4 is GND. It operates continuously when powered, making it suitable for always-on signal paths.
What is the maximum capacitive load TLC071IDGN can drive stably?
TLC071IDGN maintains stability with capacitive loads up to 100 pF when configured as a unity-gain follower, as verified by phase margin ≥32° in Figure 19 of the SLOS219F datasheet. For loads >100 pF, external isolation resistor (e.g., 20–100 Ω) between OUT and CL is recommended to preserve stability.
How does the PowerPAD thermal pad on TLC071IDGN improve performance?
The exposed thermal pad on the TLC071IDGN MSOP package reduces θJA to 52.7°C/W (vs >100°C/W for standard MSOP), enabling 2.37 W power dissipation. This allows sustained ±55 mA output at high ambient temperatures (e.g., 125°C) without thermal shutdown - critical for high-current line drivers in compact industrial modules.
Is TLC071IDGN pin-compatible with other TLC07x variants in MSOP packages?
TLC071IDGN shares the same 8-pin MSOP (DGN) footprint and pinout with TLC070IDGN, but differs from TLC072IDGN (dual-channel, different pin 1–4 assignment) and TLC073IDGN (dual-channel with SHDN). Pin compatibility is limited to TLC070IDGN only; PCB layout reuse requires verification of channel count and shutdown requirements.
