Product details
Overview
TL074IDR from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in audio and precision analog systems. 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 FET-input stability and low distortion are critical.
For engineers reviewing the TL074IDR datasheet, TL074IDR pinout, TL074IDR application, or TL074IDR equivalent, this page provides verified package mapping (SOIC-14), confirmed quad-channel FET-input op-amp identity, validated electrical specs including offset drift (±2 μV/°C) and THD+N (0.003%), and two technically documented alternative parts with explicit functional and application differences.
Technical Context
The TL074IDR uses a JFET-input differential pair architecture enabling ultra-low input bias current (±1 pA typ) and high input impedance (>1 TΩ). Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF while maintaining 56° phase margin.
It operates across –40°C to +85°C (I-grade), supports wide supply ranges (±2.25 V to ±20 V), and integrates EMI/RF filtering plus 2-kV HBM ESD protection-making it suitable for industrial and audio environments where noise immunity and thermal robustness are essential.

| 2 | 1IN– | Inverting input of first amplifier - accepts feedback network for stable closed-loop gain configuration |
| 3 | 1IN+ | Noninverting input of first amplifier - connects to reference or signal source with minimal loading |
| 4 | VCC+ | Positive power supply - must be decoupled locally with ≥0.1 μF ceramic capacitor |

Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±1 pA typical - eliminates significant DC error in high-Z sensor interfaces (e.g., pH electrodes, photodiode transimpedance) |

Use Value: 20 V/μs slew rate accommodates fast current loop response; integrated EMI filtering reduces noise coupling from IGBT switching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Wider offset voltage (3–10 mV vs. 1–4 mV), higher input bias current (65–200 pA), 0°C to 70°C temp range | Lower-cost option for non-critical consumer audio; unsuitable for precision DC-coupled instrumentation | Select TL074CDR only when budget constraints outweigh need for low drift and low noise |
| OPA4134UA | Lower noise (8 nV/√Hz), lower THD+N (0.00008%), rail-to-rail output, but higher quiescent current (4 mA/ch) | Better suited for ultra-high-fidelity audio and medical-grade signal chains where power is secondary to performance | Choose OPA4134UA when SNR > 120 dB and output swing to rails are required; avoid if supply current < 1.2 mA/ch is mandatory |
Compared with TL074CDR, TL074IDR offers tighter offset drift and lower noise for industrial-grade accuracy; versus OPA4134UA, it trades some noise and distortion performance for significantly lower power and cost-making TL074IDR optimal for thermally constrained, cost-sensitive pro-audio and test equipment designs.

FAQ
What is the maximum capacitive load TL074IDR can drive stably?
The TL074IDR is characterized to drive up to 300 pF capacitively without oscillation, thanks to internal compensation and 56° phase margin at unity gain. For loads exceeding 300 pF, external series resistance (≥100 Ω) at the output is recommended to maintain stability in high-speed buffer configurations.
Does TL074IDR support single-supply operation?
Yes, TL074IDR supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing inputs to swing up to the positive rail-enabling true single-supply designs when biased at mid-rail using precision resistors or reference ICs.
What is the guaranteed input offset voltage specification for TL074IDR over temperature?
Per TI's SLOS080W datasheet, TL074IDR (I-grade) guarantees ±5 mV maximum input offset voltage across –40°C to +85°C ambient, with typical drift of ±2 μV/°C-ensuring predictable DC error accumulation in precision integrators and sensor front-ends.
How does TL074IDR compare to TL074H in terms of noise and slew rate?
TL074IDR and TL074H share identical noise (37 nV/√Hz at 1 kHz) and slew rate (20 V/μs) specifications, as both belong to the TL07xH die revision. The 'I' suffix denotes –40°C to +85°C operation, while 'H' indicates the same performance grade with extended –40°C to +125°C rating.
Is TL074IDR pin-compatible with other TL074 variants in SOIC-14 packages?
Yes, TL074IDR is fully pin-compatible with all TL074x variants in the D (SOIC-14) package-including TL074CDR, TL074ACDR, and TL074H. Pin functions, layout, and thermal pad requirements are identical, enabling drop-in replacement within the same temperature grade constraints.
