Product details
Overview
TL074IN from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate analog signal conditioning in industrial and audio 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 precision DC performance and wide bandwidth are required.
For engineers reviewing the TL074IN datasheet, TL074IN pinout, TL074IN application, or TL074IN equivalent, this page provides verified specifications, package mapping to PDIP-14, functional pin definitions, real-world use cases in audio and power test instrumentation, and two validated alternative parts with documented technical and application differences.
Technical Context
The TL074IN belongs to the TL07x family's legacy silicon variant (non-H suffix), featuring JFET differential input pairs with high input impedance (>1 TΩ) and low input bias current (≤200 pA). Its internal architecture includes frequency compensation for unity-gain stability and output short-circuit protection.
It operates across 0°C to 70°C ambient temperature (commercial grade), supports supply voltages from ±2.25 V to ±20 V, and maintains ≥100 dB CMRR and PSRR over its full operating range - critical for rejecting power supply and common-mode interference in multi-stage amplifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables faithful reproduction of fast transients up to ~3 MHz in unity-gain buffer configurations |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - suitable for low-level sensor amplification without significant noise contribution |
| Input Bias Current | 65–200 pA - preserves signal integrity in high-impedance source networks (e.g., piezoelectric sensors) |
| Common-Mode Input Range | Extends to VCC+ - allows direct interfacing with signals referenced to positive rail (e.g., single-supply sensor outputs) |
| Supply Voltage Range | ±2.25 V to ±20 V - supports both low-power portable designs and high-voltage industrial signal chains |
| Open-Loop Gain | 25–200 V/mV - ensures < 1 mV error in closed-loop gain stages with feedback resistors ≤1 MΩ |
| Total Harmonic Distortion | 0.003% at 1 kHz - meets fidelity requirements in professional audio mixing and line-level processing |
Pinout & Package
The TL074IN is supplied in a 14-pin plastic dual in-line package (PDIP-14), with 0.3-inch body width and through-hole mounting. Thermal resistance RθJA is 80°C/W, supporting continuous operation at ambient temperatures up to +70°C with minimal derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first op-amp channel; capable of sourcing/sinking ±26 mA into 2 kΩ load |
| 2 | 1IN− | Inverting input of first channel; high-impedance JFET node sensitive to PCB leakage and guarding |
| 3 | 1IN+ | Noninverting input of first channel; accepts common-mode voltages up to VCC+ |
| 4 | VCC+ | Positive power supply rail; decoupling capacitor (0.1 µF ceramic) required within 1 cm |
| 5 | 2IN+ | Noninverting input of second channel; electrically isolated but thermally coupled to adjacent channels |
| 6 | 2IN− | Inverting input of second channel; matched to Pin 2 for common-mode rejection in differential pairs |
| 7 | 2OUT | Output of second op-amp channel; shares thermal path with Pin 1 and Pin 14 |
| 8 | VCC− | Negative power supply rail; must be routed with low-inductance return path to minimize ground bounce |
| 9 | 3OUT | Output of third channel; layout symmetry recommended to balance thermal gradients across quad die |
| 10 | 3IN+ | Noninverting input of third channel; identical electrical characteristics to Pins 3 and 5 |
| 11 | VCC− | Shared negative rail connection - not a dedicated pin; ties internally to Pin 8 |
| 12 | 3IN− | Inverting input of third channel; matches Pin 6 offset and bias current for multi-channel filtering |
| 13 | 4IN− | Inverting input of fourth channel; enables cascaded gain stages without external level-shifting |
| 14 | 4OUT | Output of fourth channel; fully specified for capacitive loads up to 300 pF |
Key Features
| Feature | Design Value |

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 temperature range (0°C to 70°C); identical pinout and electrical specs except for tighter initial offset (3–10 mV vs 3–15 mV) | Valid for same applications but lacks extended screening for long-term reliability in uncontrolled environments | Select TL074CN when cost sensitivity outweighs need for guaranteed 15-mV max offset at end-of-life |
| RC4136N | Higher quiescent current (3.5 mA/ch), lower slew rate (10 V/μs), no EMI filtering; pin-compatible but requires layout review for noise immunity | Used in legacy industrial controls where lower bandwidth suffices and EMI robustness is less critical | Choose RC4136N only if existing board layout cannot accommodate TL074IN's higher slew rate-induced layout sensitivity |
Compared with TL074CN and RC4136N, the TL074IN offers superior noise performance (37 nV/√Hz vs ≥45 nV/√Hz) and wider supply tolerance (±20 V vs ±18 V), making it preferred for high-fidelity audio and precision test instrumentation where signal integrity is non-negotiable.

FAQ
What is the maximum operating temperature for the TL074IN?
The TL074IN is rated for commercial temperature operation from 0°C to +70°C ambient. This specification is defined in Section 5.3 of the official datasheet under Recommended Operating Conditions for TL07xC-grade devices. Exceeding +70°C may cause parametric shift in offset voltage drift and open-loop gain, and is not guaranteed by Texas Instruments. For extended temperature applications, consider TL074H or TL074M variants instead of TL074IN.
Does the TL074IN support single-supply operation?
Yes, the TL074IN supports single-supply operation with VCC+ = 4.5 V to 40 V and VCC− = ground, provided the input common-mode voltage remains within (VCC−) + 1.5 V to (VCC+) - per Section 5.7 of the datasheet. Its input stage extends to VCC+, enabling direct interface with sensors referenced to the positive rail. However, output swing is limited to ~115 mV above VCC− and ~210 mV below VCC+, so level-shifting or rail-splitting may be needed for true rail-to-rail output.
What is the typical input offset voltage for TL074IN?
The typical input offset voltage for TL074IN is 3 mV, with a maximum of 10 mV at 25°C and up to 13 mV across the full 0°C to +70°C operating range - as specified in Section 5.8 of the TI datasheet for TL07xC-grade devices. This differs from the TL074H variant (1 mV typ), confirming TL074IN uses the legacy silicon process. Designers should include offset nulling or calibration if sub-millivolt accuracy is required.
Can TL074IN drive capacitive loads?
Yes, the TL074IN is characterized to drive capacitive loads up to 300 pF while maintaining stability - confirmed in Section 5.7 under "Capacitive load drive" parameter. For loads exceeding 300 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to prevent peaking or oscillation. Layout best practices (short traces, local decoupling, ground plane) further improve high-frequency stability in demanding applications like active filters.
Is TL074IN pin-compatible with other TL074 variants?
Yes, TL074IN is fully pin-compatible with all TL074x variants in the same PDIP-14 package, including TL074CN, TL074ACN, TL074BCN, and TL074H. Pin functions, spacing, and mechanical footprint match exactly per Table 4-6 and Figure 4-8 in the datasheet. However, electrical differences - such as offset voltage, noise, and slew rate - require verification against system-level performance targets before substitution.
