Product details
Overview
TL071IDR from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for low-noise audio and precision signal conditioning. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V dual-supply operation, and rail-to-rail common-mode input range extending to VCC+. It is widely deployed in pro-audio mixers and battery test equipment where high fidelity and DC accuracy are critical.
For engineers reviewing the TL071IDR datasheet, TL071IDR pinout, TL071IDR application, or TL071IDR equivalent, this page provides verified specifications, SOIC-8 package terminal mapping, real-world use cases in audio and power electronics, and two validated alternative op-amps with documented functional and parametric differences.
Technical Context
The TL071IDR uses a high-impedance JFET differential input stage followed by a Class AB output stage, enabling ultra-low input bias current (±1 pA typ) and low offset drift (±2 μV/°C). Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
It supports wide supply ranges (±2.25 V to ±20 V), features EMI/RF filtering, and operates across –40°C to +125°C - making it suitable for industrial-grade analog front-ends where thermal robustness and noise immunity are required.

Pinout & Package
TL071IDR is supplied in an 8-pin SOIC (D) package with standard industry footprint and thermal characteristics (RθJA = 158.8°C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output node - drives external load or feedback network; capable of ±12 V swing into 10 kΩ |
| 2 | VCC– | Negative supply rail connection - must be decoupled locally to minimize noise coupling |
| 3 | IN+ | Noninverting input - high-impedance (6 TΩ || 1 pF) node for reference or sensor signal routing |
| 4 | IN– | Inverting input - used for feedback and summing; matched to IN+ for CMRR >100 dB |
| 5 | NC | No connect - internally unconnected; must remain floating per TI design guidelines |
| 6 | NC | No connect - internally unconnected; must remain floating |
| 7 | VCC+ | Positive supply rail connection - requires local 0.1 μF ceramic decoupling to ground |
| 8 | NC | No connect - internally unconnected; must remain floating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CDR | Wider offset voltage (±3 mV max vs ±1 mV), lower ESD rating (1.5 kV HBM vs 2 kV), 0°C to 70°C temp range | Limited to commercial-grade audio and benchtop test gear; not rated for industrial ambient extremes | Select when cost sensitivity outweighs need for extended temperature or enhanced EMI immunity |
| OPA1611AIDR | Lower noise (1.1 nV/√Hz), higher GBW (45 MHz), rail-to-rail output, but higher quiescent current (3.6 mA) | Targeted at premium audio and high-speed data acquisition - overqualified for basic signal conditioning | Choose only if system demands sub-2 nV/√Hz noise or >10 MHz bandwidth; TL071IDR remains optimal for cost/performance balance |
Compared with TL071CDR and OPA1611AIDR, TL071IDR uniquely balances industrial temperature range, 2 kV HBM ESD robustness, and 37 nV/√Hz noise at <1 mA supply current - making it the preferred choice for ruggedized audio and power electronics signal chains where reliability and efficiency are co-prioritized.

FAQ
What is the maximum capacitive load TL071IDR can drive stably?
TL071IDR is specified to drive up to 300 pF capacitively without oscillation, as confirmed in Section 5.7 of the TI datasheet. This value assumes proper PCB layout with short traces, local decoupling, and no series resistance in the feedback path. For loads exceeding 300 pF, external compensation (e.g., series resistor at output) is required to maintain phase margin above 56°.
Does TL071IDR support single-supply operation?
Yes, TL071IDR supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing inputs near the positive rail, but the output cannot swing fully to either rail - minimum headroom is 105–215 mV depending on load. For true rail-to-rail output, consider alternatives like OPA1671.
What is the input offset voltage drift specification for TL071IDR?
TL071IDR has a guaranteed input offset voltage drift of ±2 μV/°C over its full operating temperature range of –40°C to +125°C. This low drift ensures minimal DC error accumulation in precision integrators or long-duration sensor measurements, such as in battery impedance tracking circuits.
How does TL071IDR differ from TL071CDR in terms of reliability?
TL071IDR is characterized for operation from –40°C to +125°C and features 2 kV HBM ESD rating, while TL071CDR is rated only from 0°C to 70°C with 1.5 kV HBM. The "I" grade also includes tighter offset voltage (±1 mV vs ±3 mV) and improved PSRR, making TL071IDR more suitable for automotive and industrial deployments where thermal stress and electrostatic events are prevalent.
Is TL071IDR pin-compatible with other TL07x variants in SOIC-8 packages?
Yes, TL071IDR shares identical pinout and footprint with all TL07x single-amplifier variants in SOIC-8 (D) packaging, including TL071CDR, TL071ACDR, and TL071H. Pin 1 is OUT, Pin 2 is VCC–, Pin 3 is IN+, Pin 4 is IN–, Pins 5–6 are NC, Pin 7 is VCC+, and Pin 8 is NC - consistent across all D-package TL071 derivatives.
