Product details
Overview
TL074IYDT from STMicroelectronics is a quad JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 15 nV/√Hz input voltage noise, 16 V/µs slew rate, ±11 V input common-mode range (with ±15 V supply), and 2 MHz gain-bandwidth product - enabling high-fidelity preamplifier, active filter, and sensor interface designs in industrial instrumentation and professional audio equipment.
For engineers reviewing the TL074IYDT datasheet, TL074IYDT pinout, TL074IYDT application, or TL074IYDT equivalent, this page provides verified electrical parameters, SO14 package layout, real-world use cases including audio distribution amplifiers and bandpass filters, and validated alternatives for design flexibility and supply continuity.
Technical Context
The TL074IYDT integrates four matched JFET-input op-amps on a single monolithic die, using high-voltage JFETs for input stages and bipolar transistors for output drivers. Its internal frequency compensation ensures unity-gain stability without external components, while latch-up-free operation supports robust performance across temperature extremes.
It operates over ±6 V to ±18 V dual supplies (or 12–36 V single supply), with rail-to-rail output swing limited by load (±12 V into 10 kΩ) and input common-mode range extending to within 3 V of either rail. The device features output short-circuit protection and 10¹² Ω input resistance - critical for high-impedance sensor interfacing and passive filter buffering.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Op-Amp 1) | Differential node for first amplifier; requires matched trace routing to minimize offset drift |
| 2 | Non-inverting Input (Op-Amp 1) | High-impedance reference point; sensitive to EMI if unshielded |
| 3 | Output (Op-Amp 1) | Capable of ±12 V swing into 10 kΩ; current-limited to 60 mA short-circuit |
| 4 | VCC− (Negative Supply) | Return path for all four amplifiers; must be low-inductance connection to ground plane |

| 6 | Non-inverting Input (Op-Amp 2) | Electrically isolated input node; usable as independent buffer or comparator reference |
| 7 | Output (Op-Amp 2) | Same drive capability as Pin 3; supports cascaded gain stages without level-shifting |
| 8 | VCC+ (Positive Supply) | Power rail for all amplifiers; decoupling capacitor (100 nF ceramic) required within 5 mm |
| 9 | Inverting Input (Op-Amp 3) | Third channel input; identical bias and noise specs to Pins 1 and 5 |
| 10 | Non-inverting Input (Op-Amp 3) | Enables three-channel parallel processing (e.g., stereo + subwoofer crossover) |
| 11 | Output (Op-Amp 3) | Supports simultaneous multi-output filtering without inter-stage coupling |
| 12 | Inverting Input (Op-Amp 4) | Fourth channel input; used in quad-band equalizers or differential receiver pairs |
| 13 | Non-inverting Input (Op-Amp 4) | Provides reference for fourth channel; suitable for DC-biasing sensor bridges |
| 14 | Output (Op-Amp 4) | Final output stage; capable of driving 2 kΩ loads with <0.01% THD at 1 kHz |

|---|---|
|
Use Scenario: Distributing a single line-level audio source to multiple destinations (e.g., recording console, monitor feed, broadcast encoder) without signal degradation or crosstalk. IC Role / Device Role / Timing Role: Quad op-amp configured as unity-gain buffers - each channel isolates one output path while preserving amplitude and phase integrity. Use Value: Achieves ≤0.01% THD across 20 Hz–20 kHz and >120 dB channel separation, eliminating ground loops and impedance mismatch issues. |
Use Scenario: Extracting narrowband signals (e.g., 100 kHz carrier detection in ultrasonic sensing or RF demodulation). IC Role / Device Role / Timing Role: Configured as positive-feedback active bandpass topology - one amplifier per stage in cascaded second-order sections. Use Value: Delivers Q = 69 and precise center frequency stability without trimming, enabled by matched JFET pairs and low thermal drift (10 µV/°C offset). |
| DC-Coupled Sensor Interface | Industrial Signal Conditioning |
|
Use Scenario: Amplifying low-level outputs from strain gauges, thermopiles, or piezoelectric sensors where DC accuracy and low-frequency noise matter. IC Role / Device Role / Timing Role: Instrumentation-grade front-end with dual-op-amp difference amplifier configuration - two amplifiers form precision gain stage, third handles reference buffering. Use Value: 3 mV max input offset and 10 µV/°C drift ensure sub-0.1% measurement error over -40°C to +85°C ambient ranges. |
Use Scenario: Converting 4–20 mA current-loop sensor outputs to calibrated 0–10 V analog signals in PLC I/O modules. IC Role / Device Role / Timing Role: Quad op-amp implements current-to-voltage conversion, level shifting, filtering, and output driver - one per functional block. Use Value: 10¹² Ω input resistance prevents loop current loss; ±125°C rating supports operation inside sealed industrial enclosures. |
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 |
|---|---|---|---|
| TL074CDT | Commercial grade (0°C to +70°C), lower CMRR (70 dB min), same SO14 package | Restricted to indoor consumer electronics; not rated for extended temperature or automotive environments | Select when cost sensitivity outweighs environmental ruggedness and long-term drift requirements |
| NE5532DR | Bipolar input (not JFET), higher bias current (800 nA), lower noise (5 nV/√Hz), dual-channel only | Better for ultra-low-noise audio but unsuitable for high-Z sources; requires two packages for quad functionality | Choose for studio-grade preamps where noise dominates over input impedance constraints |
Compared with TL074CDT, TL074IYDT offers guaranteed operation to +125°C and 16 dB higher CMRR - critical for factory-floor signal conditioning. Versus NE5532DR, it trades 10× lower input bias for 3× higher voltage noise, making it superior for piezoelectric or photodiode interfaces but less optimal for microphone preamps demanding lowest possible en.

FAQ
What is the maximum supply voltage for TL074IYDT?
The absolute maximum supply voltage is ±18 V (36 V total), but the recommended operating range is ±6 V to ±18 V. Exceeding ±18 V risks permanent damage to the JFET input stage, and operation below ±6 V may cause reduced output swing and increased distortion due to insufficient headroom for internal biasing.
Does TL074IYDT require external compensation capacitors?
No - TL074IYDT is internally frequency-compensated for unity-gain stability. Adding external compensation capacitors is unnecessary and may degrade phase margin or bandwidth. This simplifies PCB layout and reduces bill-of-materials count in voltage-follower, non-inverting, and inverting amplifier configurations.
How does TL074IYDT differ from TL074IDT?
TL074IYDT adds AEC-Q100 qualification and advanced screening per AEC-Q001/Q002, while TL074IDT meets standard industrial specifications. Both share identical electrical specs and SO14 packaging, but TL074IYDT undergoes additional reliability testing for automotive auxiliary modules - including extended temperature cycling and HTOL stress.
Can TL074IYDT drive capacitive loads directly?
TL074IYDT can drive up to 100 pF without instability, as confirmed in Figure 15 of the datasheet. For larger capacitive loads (e.g., coaxial cables or ADC input filters), a series isolation resistor (20–100 Ω) between output and load is required to maintain phase margin and prevent ringing - a design practice documented in ST Application Note AN2711.
