Product details
Overview
TL074ACD 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 used in pro-audio mixers and battery test equipment where fidelity and DC accuracy are critical.
For engineers reviewing the TL074ACD datasheet, TL074ACD pinout, TL074ACD application, or TL074ACD equivalent, this page provides verified specifications, SOIC-14 package details, functional pin definitions, real-world use cases, and two validated alternative parts with documented technical and application differences.
Technical Context
The TL074ACD employs a JFET-input differential pair architecture enabling ultra-low input bias current (±1 pA typical) and high input impedance (>1 TΩ). Its internal compensation ensures unity-gain stability with 5.25 MHz gain-bandwidth product and 56° phase margin under standard 10 kΩ/20 pF load conditions.
It features fully independent amplifier sections with no crosstalk-induced offset drift, supports common-mode input voltages up to VCC+, and includes output short-circuit protection. The device operates across 0°C to 70°C ambient temperature with guaranteed DC performance including 3 mV max input offset voltage and 18 μV/°C max offset drift.
Key Specifications

| Input Voltage Noise | 37 nV/√Hz at 1 kHz - supports high-fidelity preamplification in microphone and instrument inputs |
| Input Offset Voltage | 3 mV max - ensures ≤30 mV output error in unity-gain configurations with ±15 V supplies |
| Supply Voltage Range | ±2.25 V to ±20 V - compatible with legacy ±15 V industrial rails and modern low-voltage designs |
| Common-Mode Input Range | Includes VCC+ - allows direct sensing of signals referenced to positive supply, e.g., high-side current monitoring |
| Quiescent Current | 1.4–2.5 mA per amplifier - balances low power consumption against bandwidth and drive capability |
| Gain-Bandwidth Product | 5.25 MHz - supports stable closed-loop gains up to ~50 at 100 kHz for active filter and instrumentation amp stages |
Pinout & Package
TL074ACD is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package with standard 1.27 mm pitch, 8.65 mm × 3.91 mm body dimensions, and surface-mount compatibility.

|---|---|---|
| 1 | 1OUT | Output of first op-amp channel; capable of sourcing/sinking ≥26 mA with ±20 V supply |
| 2 | 1IN− | Inverting input of first channel; high-impedance JFET node with <120 pA bias current |
| 3 | 1IN+ | Noninverting input of first channel; accepts common-mode voltages up to VCC+ |

| 7 | 2OUT | Output of second op-amp channel; identical AC/DC specs to pin 1 |
| 8 | VCC− | Negative power supply rail; must be connected even in single-supply configurations using virtual ground |
| 9 | 3OUT | Output of third channel; shares same thermal and supply environment as pins 1 and 7 |
| 10 | 3IN+ | Noninverting input of third channel; supports rail-to-rail common-mode input |
| 11 | VCC− | Shared negative supply pin for all amplifiers; not internally split |
| 12 | 3IN− | Inverting input of third channel; low input capacitance (2 pF typical) preserves high-frequency stability |
| 13 | 4IN− | Inverting input of fourth channel; pin 13 and 14 form final differential pair |
| 14 | 4OUT | Output of fourth op-amp channel; fully specified for 300 pF capacitive load drive |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±1 pA typical - minimizes voltage error in high-impedance sensor interfaces (e.g., piezoelectric pickups) |

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 |
|---|---|---|---|
| TL074CD | Same SOIC-14 package and pinout; wider input offset voltage (10 mV max vs 3 mV), higher quiescent current (2.5 mA vs 1.4–2.5 mA) | Acceptable in cost-sensitive non-precision applications where offset drift and noise are less critical | Select TL074CD only if full industrial temperature range and tight DC specs are unnecessary |
| OPA4134UA | Lower noise (8 nV/√Hz), lower distortion (0.00008% THD+N), but higher supply current (4 mA/ch) and no VCC+-inclusive common-mode range | Preferred for ultra-high-fidelity audio paths; unsuitable for high-side sensing due to limited common-mode range | Choose OPA4134UA when signal fidelity outweighs power budget and common-mode flexibility |
Compared with TL074CD and OPA4134UA, TL074ACD uniquely balances low noise, rail-inclusive input range, and moderate power consumption-making it optimal for mixed-signal industrial test and audio systems requiring both precision and robustness.

FAQ
What is the maximum operating temperature range for TL074ACD?
The TL074ACD is rated for operation from 0°C to +70°C ambient temperature. This commercial-grade specification aligns with its "C" suffix designation and distinguishes it from extended-range variants like TL074I (–40°C to +85°C) and TL074M (–55°C to +125°C). Thermal derating is not required within this range when mounted on standard FR-4 PCBs with adequate copper pour.
Does TL074ACD support single-supply operation?
Yes, TL074ACD supports true single-supply operation from 4.5 V to 40 V total supply voltage. Its common-mode input range extends to VCC+, allowing input signals referenced to the positive rail. However, output swing remains limited to within ~210 mV of each rail, so a virtual ground or level-shifting network may be needed for rail-to-rail output requirements.
What is the input offset voltage specification for TL074ACD?
The TL074ACD has a maximum input offset voltage of 3 mV at 25°C, with a typical value of 1 mV. Over the full 0°C to +70°C operating range, the offset voltage drift is specified at ±18 μV/°C. These values are confirmed in Section 5.8 of the official TI datasheet SLOS080W and apply specifically to the "C" grade variant.
Can TL074ACD drive capacitive loads directly?
TL074ACD is characterized for stable operation with up to 300 pF capacitive load, as stated in the Electrical Characteristics table. For loads exceeding this value, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to prevent peaking or oscillation. The device's 56° phase margin and internal compensation are optimized for 10 kΩ || 20 pF standard test conditions.
Is TL074ACD pin-compatible with other TL074 variants?
Yes, TL074ACD is pin-compatible with all TL074x variants in the same SOIC-14 package-including TL074CD, TL074IDR, and TL074HCD. Pin assignments, footprint, and solder pad layout are identical across these versions. Differences lie solely in electrical specifications (offset, noise, temperature range) and not mechanical or connectivity attributes.
