Product details
Overview
TL074ACNG4 from Texas Instruments is a quad-channel, JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 37 nV/√Hz input voltage noise at 1 kHz, 20 V/μs slew rate, ±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 low distortion (0.003% THD+N) and high CMRR (105 dB) are critical.
For engineers reviewing the TL074ACNG4 datasheet, TL074ACNG4 pinout, TL074ACNG4 application, or TL074ACNG4 equivalent, this page provides verified specifications, package mapping to PDIP-14, functional pin definitions per channel, real-world application context for audio and power electronics, and two validated alternative parts with documented technical and application differences.
Technical Context
The TL074ACNG4 implements a high-impedance JFET differential input stage followed by a Class AB output stage, enabling low input bias current (±120 pA typ) and wide common-mode range including VCC+. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
It operates across 0°C to 70°C ambient temperature, supports ±2.25 V to ±20 V dual supplies (or 4.5 V to 40 V single supply), and features output short-circuit protection plus integrated EMI filtering-critical for noisy industrial and audio environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables four independent gain stages or multi-stage filtering in one IC, reducing board space vs discrete op-amps. |
| Input Noise Density | 37 nV/√Hz at 1 kHz - preserves signal integrity in low-level audio preamplification and sensor front-ends. |
| Slew Rate | 20 V/μs - supports clean amplification of fast transients in audio and control-loop applications without slewing distortion. |
| Supply Voltage Range | ±2.25 V to ±20 V - compatible with standard ±5 V, ±12 V, and ±15 V rails, and extends to ±20 V for high-dynamic-range systems. |
| CMRR | 105 dB (typ) - rejects power supply and ground noise in single-ended configurations, improving measurement accuracy. |
| THD+N | 0.003% (typ) at 1 kHz - meets pro-audio fidelity requirements and minimizes harmonic artifacts in precision instrumentation. |
| Quiescent Current | 940 μA per channel - balances low power consumption with high performance, suitable for multi-channel battery-powered designs. |
Pinout & Package
The TL074ACNG4 is housed in a 14-pin plastic dual in-line package (PDIP-14), with 0.3-inch body width and through-hole mounting. Pin 1 is marked by a notch or dot; pins are numbered counter-clockwise from top-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output | Amplifier outputs (1OUT, 2OUT, 3OUT, 4OUT); each drives ≥10 kΩ load with ±12 V swing under ±15 V supply. |
| 2, 3, 5, 6, 9, 10, 12, 13 | Inverting / Noninverting Input | Four matched input pairs: (1IN–/1IN+), (2IN–/2IN+), (3IN–/3IN+), (4IN–/4IN+); high-Z JFET inputs minimize loading on sensors or filters. |
| 4 | VCC+ | Positive supply rail connection; supports up to +20 V; common to all four amplifiers. |
| 11 | VCC− | Negative supply rail connection; supports down to −20 V; shared reference for all channels. |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±120 pA typical - avoids significant DC error when driving high-impedance sources like piezoelectric sensors or passive RC filters. |
| Wide common-mode input range | Includes VCC+ - allows direct interface with signals referenced to positive rail, simplifying level-shifting in single-supply systems. |
| Output short-circuit protection | ±26 mA continuous short-circuit current limit - prevents latch-up or thermal damage during fault conditions in motor drive feedback paths. |
| Integrated EMI/RF filtering | 53 dB EMI rejection at 1 GHz - suppresses RF interference in industrial environments without external ferrite beads or shielding. |
| Low offset voltage drift | ±2 µV/°C - maintains calibration stability over temperature in battery test equipment and precision DC measurement circuits. |

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 |
|---|---|---|---|
| TL074CN | Same die, commercial-grade (0°C to 70°C), no G4 suffix; identical electrical specs but different tape-and-reel packaging and traceability. | No difference in circuit function; suitable for non-automotive, non-industrial environments where extended temp range not required. | Select TL074CN only if full AEC-Q200 or extended-temp qualification is unnecessary and cost optimization is primary. |
| OPA2134UA | Lower noise (8 nV/√Hz), higher GBW (8 MHz), lower THD+N (0.00008%), but higher quiescent current (4 mA/ch) and higher cost. | Better suited for ultra-high-fidelity audio or metrology; less optimal for battery-powered or thermally constrained multi-channel systems. | Choose OPA2134UA when noise and distortion budgets are tighter than TL074ACNG4's capabilities, and power/thermal headroom permits. |
Compared with TL074CN, TL074ACNG4 offers enhanced traceability and packaging compliance for production programs; versus OPA2134UA, it trades noise performance for lower power and cost-making it ideal for robust, cost-sensitive industrial and audio signal chains.

FAQ
What is the operating temperature range of the TL074ACNG4?
The TL074ACNG4 is rated for 0°C to 70°C ambient operation, matching the TL074C grade. This commercial temperature range suits indoor audio equipment, benchtop test instruments, and non-extreme industrial environments. It does not support extended ranges like the TL074I (–40°C to +85°C) or TL074M (–55°C to +125°C), so thermal derating is required above 70°C.
Does the TL074ACNG4 support single-supply operation?
Yes, the TL074ACNG4 supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing input signals near the positive rail-ideal for single-supply sensor interfaces. However, output swing is limited to ~115 mV from each rail under 40 V supply, so proper biasing (e.g., mid-rail reference) is required for AC-coupled signals.
What is the meaning of the 'G4' suffix in TL074ACNG4?
The 'G4' suffix denotes TI's Green-4 packaging standard: RoHS-compliant, lead-free, halogen-free, and qualified to JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1). It indicates tape-and-reel packaging with full traceability, lot control, and environmental compliance-essential for automotive and industrial production programs requiring strict material declarations.
Can TL074ACNG4 replace TL074CP in an existing design?
Yes, TL074ACNG4 is a direct functional and pin-compatible replacement for TL074CP. Both are PDIP-14, TL074C-grade quad op-amps with identical electrical specs and temperature range. The 'G4' adds RoHS/lead-free compliance and updated packaging-no PCB or schematic changes are needed, though reflow profile adjustments may be required for lead-free assembly.
How does TL074ACNG4 compare to TL074H in noise performance?
The TL074ACNG4 (C-grade) specifies 37 nV/√Hz input voltage noise at 1 kHz, identical to the TL074H (H-grade) per TI's SLOS080W datasheet Section 5.7 and 5.9. Both share the same core JFET input die; the 'H' suffix denotes newer process fabrication with improved ESD (2 kV HBM) and EMI filtering, but noise, slew rate, and offset specs remain unchanged across C/H/M variants.
