Product details
Overview
TL074IDT from STMicroelectronics is a low-noise JFET-input quad operational amplifier in SO14 package, rated for -40°C to +125°C operation. It delivers 16 V/µs typical slew rate, 15 nV/√Hz input voltage noise, 0.01% THD at 1 kHz, ±11 V common-mode range, and 80 dB CMRR - enabling high-fidelity audio signal conditioning and precision DC-coupled amplification in industrial sensor interfaces.
For engineers reviewing the TL074IDT datasheet, TL074IDT pinout, TL074IDT application, or TL074IDT equivalent, key selection criteria include JFET-input bias current (≤200 pA), rail-to-rail output swing capability (±12 V into 10 kΩ), thermal stability over extended temperature range, and SO14 footprint compatibility with legacy TL07x designs.
Technical Context
The TL074IDT integrates four matched JFET-input op-amps on a single die with internal frequency compensation and high-voltage bipolar output stages. Its architecture supports unity-gain stable operation while maintaining 3 MHz gain-bandwidth product and 45° phase margin under standard test conditions (VCC = ±15 V, RL = 2 kΩ, CL = 100 pF).
Each amplifier features independent input stage protection against differential overvoltage (±30 V) and latch-up-free operation. The device operates from ±6 V to ±18 V supplies, with input common-mode range extending to within 1.5 V of either rail and output swing limited by load-dependent saturation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 16 V/µs typical - enables clean 100 kHz sine wave reproduction without slew-induced distortion |
| Input Voltage Noise | 15 nV/√Hz at 1 kHz - critical for low-level audio preamplification and sensor signal integrity |
| THD + N | 0.01% at 1 kHz, 2 Vpp output - meets high-fidelity analog signal chain requirements |
| Common-Mode Range | ±11 V (with ±15 V supply) - supports wide dynamic range input signal handling |
| Supply Voltage Range | ±6 V to ±18 V - compatible with dual-rail industrial and audio power architectures |
| Input Bias Current | 200 pA max at +125°C - preserves accuracy in high-impedance transducer interfaces |

Pinout & Package
TL074IDT is housed in a 14-pin SOIC (SO14) plastic micropackage with 1.27 mm pitch, 8.75 mm length, and 4.0 mm width. Thermal resistance junction-to-ambient is 105 °C/W (typical), suitable for surface-mount reflow assembly.

| 6 | Non-inverting Input (Amp 2) | Second channel reference input; matched offset and bias characteristics |
| 7 | Output (Amp 2) | Dedicated output with same drive strength and noise performance as Amp 1 |
| 8 | VCC+ (Positive Supply) | Primary positive rail connection; decoupling capacitor required near pin |
| 9 | Inverting Input (Amp 3) | Third channel inverting input; identical layout and matching to Amps 1 & 2 |
| 10 | Non-inverting Input (Amp 3) | Third channel non-inverting input; maintains <1 mV inter-channel offset match |
| 11 | Output (Amp 3) | Third independent output; supports cascaded filter or multi-path signal routing |
| 12 | Inverting Input (Amp 4) | Fourth channel inverting input; fully functional with no shared substrate coupling |
| 13 | Non-inverting Input (Amp 4) | Fourth channel reference input; optimized for low-frequency stability |
| 14 | Output (Amp 4) | Final output stage; enables full quad functionality in compact SO14 footprint |

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 |
|---|---|---|---|
| TL084CDT | Higher input bias current (up to 4 nA), wider offset voltage spread (10 mV max), same SO14 package | Less suitable for ultra-high-Z sources like piezoelectric sensors or photodiode transimpedance stages | Select when cost sensitivity outweighs low-noise requirement and temperature range is limited to 0°C–70°C |
| OPA4134UA | Lower noise (8 nV/√Hz), lower THD (0.00008%), rail-to-rail output, but ±18 V supply max and SO14 not available (SO14 only for TL074IDT) | Requires PCB redesign due to different pinout and package; superior for audiophile-grade designs | Choose when upgrading audio systems where noise floor and distortion are primary constraints |
Compared with TL074IDT, TL084CDT trades noise and bias performance for lower cost and broader commercial availability, while OPA4134UA offers measurable audio performance gains at the expense of footprint compatibility and higher unit price.

FAQ
Is TL074IDT pin-compatible with other TL07x variants in SO14 package?
Yes, TL074IDT shares identical SO14 pinout with TL074CDT, TL074AIDT, and TL074BIDT. All variants maintain consistent terminal assignments across temperature grades and offset specifications, enabling drop-in replacement in existing layouts without redesign.
What is the maximum safe continuous output short-circuit duration for TL074IDT?
TL074IDT features internal short-circuit protection rated for infinite duration under specified thermal limits. However, sustained short-circuit operation must remain within the 680 mW total power dissipation limit - meaning simultaneous shorts across all four amplifiers require strict ambient temperature control below +70°C.
Can TL074IDT operate from a single +12 V supply?
No - TL074IDT is a dual-supply op-amp requiring both VCC+ and VCC– rails. It cannot function with a single-ended supply unless a virtual ground is generated externally. Its input common-mode and output swing specifications assume symmetric ±Vs operation, and datasheet parameters are validated only under dual-rail conditions.
Does TL074IDT meet automotive qualification standards?
TL074IDT itself is not AEC-Q100 qualified. For automotive applications, ST offers the TL074IYDT variant, which undergoes additional screening per AEC-Q001/Q002 and is characterized across -40°C to +125°C with enhanced reliability testing - TL074IDT lacks this qualification and is intended for industrial and commercial use only.
