Texas Instruments TL071CDRG4

Overview

TL071CDRG4 from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for low-noise audio and precision analog 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 stability are critical.

For engineers reviewing the TL071CDRG4 datasheet, TL071CDRG4 pinout, TL071CDRG4 application, or TL071CDRG4 equivalent, this page provides verified specifications, SOIC-8 package terminal mapping, real-world use cases in audio and test instrumentation, and two validated alternative parts with documented functional and parametric differences.

Technical Context

The TL071CDRG4 uses a high-impedance JFET differential input stage enabling ultra-low input bias current (≤120 pA typ) and low input offset voltage drift (2 μV/°C). Its internal compensation ensures stable unity-gain operation with ≤20 pF capacitive load, and its EMI-hardened architecture achieves 53 dB EMI rejection at 1 GHz.

It operates across 0°C to 70°C ambient temperature with 1.4–2.5 mA quiescent current per amplifier, supports ±15 V standard supply rails, and features output short-circuit protection. The device maintains ≥100 dB CMRR and PSRR over frequency while delivering 0.003% THD+N at 1 kHz under 6 VRMS output conditions.

FAQ

What is the maximum supply voltage for TL071CDRG4?

The TL071CDRG4 supports a total supply voltage range of 4.5 V to 40 V (±2.25 V to ±20 V). Absolute maximum ratings specify 42 V for non-NS/PS packages, but TI recommends staying within 40 V for reliable long-term operation. Exceeding 40 V risks exceeding junction temperature limits and degrading offset drift performance.

Does TL071CDRG4 have rail-to-rail input or output capability?

TL071CDRG4 features rail-to-rail common-mode input range-including VCC+-but does not provide rail-to-rail output swing. Its output typically swings within 105–215 mV of each rail under 10 kΩ load, as specified in the Electrical Characteristics table. For true rail-to-rail output, consider alternatives like the OPA1671IDR.

What is the input bias current specification for TL071CDRG4 at 25°C?

At TA = 25°C and VS = ±15 V, the TL071CDRG4 exhibits a typical input bias current of 65 pA, with a maximum of 200 pA across the full 0°C to 70°C operating range. This ultra-low value stems from its JFET input stage and enables high-impedance sensor interfacing without significant DC error.

Can TL071CDRG4 drive capacitive loads directly?

Yes, TL071CDRG4 is characterized to drive up to 300 pF capacitive load without oscillation, per its Electrical Characteristics table. However, for loads >100 pF, TI recommends adding a small series resistor (e.g., 10–50 Ω) between the output and capacitor to maintain phase margin and prevent peaking-especially in unity-gain configurations.

Is TL071CDRG4 suitable for single-supply operation?

Yes, TL071CDRG4 supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing input signals referenced to ground or mid-supply. For proper DC biasing, configure the noninverting input at VCC/2 using matched resistors or a dedicated reference, and ensure output swing remains within valid headroom limits.
