Product details
Overview
TLC071IDR 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 TLC071IDR datasheet, TLC071IDR pinout, TLC071IDR application, or TLC071IDR equivalent, this page delivers verified electrical specifications, thermal performance data across −40°C to +125°C, shutdown-mode current (125 µA), slew rate (16 V/µs), and package-specific layout guidance for SOIC-8 (D) packaging - all critical for robust single-supply op-amp selection in automotive and industrial control systems.
Technical Context
The TLC071IDR employs TI's patented LBC3 BiCMOS process, integrating a high-impedance CMOS input stage with a bipolar output stage to simultaneously achieve low input bias current (≤700 pA), high AC bandwidth (10 MHz GBW), and strong output drive (57 mA sourcing / 55 mA sinking). Its internal architecture supports stable unity-gain operation with ≥32° phase margin at 50 pF load capacitance.
Designed for single-supply systems, it operates with common-mode input range extending from 0.5 V above ground to VDD − 0.8 V, and includes an active-low shutdown pin (SHDN) that reduces supply current to 125 µA per channel. The device is rated for extended industrial temperature range (−40°C to +125°C) and meets stringent PSRR (100 dB) and CMRR (95 dB) requirements under varying supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable closed-loop operation up to 10× gain at 1 MHz or unity-gain buffer applications at full audio bandwidth. |
| Slew Rate | +16 V/µs / −19 V/µs - supports fast transient response in pulse amplification and active filter stages without slew-induced distortion. |
| Output Drive | ±55 mA continuous output current - drives low-impedance loads (e.g., 600 Ω audio lines, capacitive DAC buffers) without external boost circuitry. |
| Input Offset Voltage | 60 µV typical (25°C), ≤2 mV max over full temperature range - ensures DC accuracy in precision instrumentation and sensor signal chains. |
| Supply Range | 4.5 V to 16 V single supply - compatible with 5 V, 12 V, and 15 V industrial rails; eliminates need for dual supplies in legacy designs. |
| Shutdown Current | 125 µA per channel - enables power gating in battery-powered or energy-conscious systems without compromising wake-up latency (ton = 0.47 µs @ 12 V). |
| Input Noise | 7 nV/√Hz @ 1 kHz - preserves SNR in low-level signal amplification (e.g., thermocouple, strain gauge, microphone preamps). |
Pinout & Package
Package: SOIC-8 (D), 8-pin plastic small-outline integrated circuit, surface-mount, tape-and-reel compatible (R suffix). Thermal resistance θJA = 176°C/W; rated for 710 mW power dissipation at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or grounded per layout best practice; no functional role. |
| 2 | IN− | Inverting input - high-impedance CMOS node; requires matched trace impedance and guard ring for low-noise applications. |
| 3 | IN+ | Non-inverting input - same high-impedance CMOS node; used for unity-gain follower or differential input configurations. |
| 4 | GND | Analog ground reference - must connect to clean, low-impedance system ground plane; separate from digital ground if mixed-signal PCB. |
| 5 | SHDN | Active-low shutdown control - logic low (≤0.8 V) disables amplifier and reduces IDD to 125 µA; pulled high internally when unused. |
| 6 | VDD | Positive supply rail - accepts 4.5–16 V; requires local 0.1 µF ceramic decoupling capacitor placed within 2 mm of pin. |
| 7 | OUT | Amplifier output - capable of ±55 mA drive into resistive or capacitive loads; may require series resistor for stability with >100 pF cables. |
| 8 | NC | No internal connection - identical to Pin 1; no routing or connection required. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input (pA-level bias current) with bipolar output (high current drive), eliminating trade-off between input impedance and output strength. |
| Rail-to-Rail Output Swing | Drives within 0.5 V of GND and within 1.5 V of VDD - maximizes dynamic range in single-supply systems without level-shifting circuitry. |
| Extended Temperature Range | Specified from −40°C to +125°C - qualified for under-hood automotive, motor control feedback, and industrial PLC analog modules. |
| Low-Noise Input Stage | 7 nV/√Hz input voltage noise at 1 kHz - enables high-fidelity amplification of microvolt-level sensor signals without added filtering overhead. |
| High PSRR and CMRR | 100 dB supply rejection and 95 dB common-mode rejection - maintains accuracy in noisy environments (e.g., switch-mode power supply proximity). |

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), higher quiescent current (800 µA), no shutdown pin. | Limited to lower-speed precision applications; unsuitable for high-current or power-gated designs. | Choose OPA2340UA only when ultra-low offset drift (<0.5 µV/°C) outweighs bandwidth and power needs. |
| LM7321MA | Higher output current (±80 mA), wider supply range (2.7–36 V), but higher input noise (15 nV/√Hz) and no shutdown mode. | Better for high-voltage industrial actuator drivers; less suitable for low-noise sensor front-ends. | Select LM7321MA when driving >100 mA loads or operating beyond 16 V; avoid where noise floor <10 nV/√Hz is mandatory. |
Compared with OPA2340UA and LM7321MA, the TLC071IDR uniquely balances 10 MHz bandwidth, ±55 mA drive, 7 nV/√Hz noise, and 125 µA shutdown current in a single SOIC-8 package - making it optimal for cost-sensitive, thermally demanding, and power-aware industrial analog signal paths.

FAQ
What is the operating temperature range for the TLC071IDR?
The TLC071IDR is specified for operation from −40°C to +125°C, matching the "I" temperature grade designation. This extended industrial range is validated across all key parameters including input offset voltage, supply current, and output drive capability - making it suitable for under-hood automotive, motor control, and factory automation applications where ambient temperatures exceed standard commercial limits.
Does the TLC071IDR support rail-to-rail input or output?
The TLC071IDR supports rail-to-rail output swing - delivering within 0.5 V of GND and within 1.5 V of VDD - but its input common-mode range is limited to 0.5 V above GND to VDD − 0.8 V. It does not feature rail-to-rail input; therefore, input signals must remain within this defined VICR window to avoid phase reversal or increased distortion.
Can the TLC071IDR be used in a dual-supply configuration?
Yes, the TLC071IDR supports split-supply operation from ±2.25 V to ±8 V, as confirmed in the Recommended Operating Conditions table. When used in dual-supply mode, its input common-mode range extends symmetrically, and performance metrics (e.g., slew rate, noise, CMRR) remain consistent - enabling reuse in legacy ±5 V or ±12 V systems without redesign.
What is the purpose of the SHDN pin on the TLC071IDR?
The SHDN pin on the TLC071IDR is an active-low shutdown control that reduces supply current per channel from 1.9 mA to 125 µA when pulled ≤0.8 V. It features fast enable/disable timing (ton = 0.47 µs, toff = 2.5 µs @ 12 V), allowing dynamic power management in portable instruments, battery-backed sensors, or multi-channel systems where channel-by-channel sleep control is required.
Is the TLC071IDR pin-compatible with the TL071CP?
No, the TLC071IDR is not pin-compatible with the TL071CP. While both are single op-amps in SOIC-8 packages, the TLC071IDR includes a dedicated SHDN pin (Pin 5), whereas the TL071CP uses Pin 5 as the offset null pin. Substituting one for the other without PCB revision will result in incorrect shutdown behavior or loss of offset trimming capability.
