Product details
Overview
TL074CDG4 from Texas Instruments is a quad-channel, JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. 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 deployed in pro-audio mixers and battery test equipment where high fidelity and DC accuracy are critical.
For engineers reviewing the TL074CDG4 datasheet, TL074CDG4 pinout, TL074CDG4 application, or TL074CDG4 equivalent, this page provides verified electrical specifications, SOIC-14 package details, functional pin roles, real-world use cases in audio and power electronics, and two validated alternative parts with documented technical and application differences.
Technical Context
The TL074CDG4 implements a high-impedance JFET differential input stage followed by a Class AB output stage, enabling low input bias current (±1 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 supply voltages from ±2.25 V to ±20 V, and achieves 5.25 MHz gain-bandwidth product with 125 dB open-loop gain - making it suitable for both wideband AC coupling and precision DC-coupled instrumentation circuits.
Key Specifications

| Input Bias Current | ±1 pA typical - minimizes voltage error in high-impedance source applications like photodiode amplifiers |
| Common-Mode Input Range | Includes VCC+ - allows direct interfacing with rail-referenced sensors and single-supply-compatible configurations |
| Supply Voltage Range | ±2.25 V to ±20 V (4.5 V to 40 V total) - accommodates legacy ±15 V systems and modern low-voltage industrial designs |
| Offset Voltage Drift | ±2 μV/°C - ensures stable DC performance over temperature in precision measurement front-ends |
| Quiescent Current | 940 μA per channel - balances low-power operation with high-speed capability for battery-powered instruments |
Pinout & Package
TL074CDG4 is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package, surface-mount compatible with standard reflow profiles and IPC-7351B land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first op-amp channel - drives external load or next stage with rail-swing capability |
| 2 | 1IN− | Inverting input of first channel - accepts feedback network or inverted signal path |
| 3 | 1IN+ | Noninverting input of first channel - connects to reference, sensor, or signal source |
| 4 | VCC+ | Positive power supply rail - must be decoupled locally with 0.1 μF ceramic capacitor |
| 5 | 2IN+ | Noninverting input of second channel - electrically isolated from other channels for independent signal paths |
| 6 | 2IN− | Inverting input of second channel - used for differential or inverting gain configurations |
| 7 | 2OUT | Output of second op-amp channel - shares same thermal and layout constraints as Pin 1 |
| 8 | VCC− | Negative power supply rail - requires symmetric decoupling to minimize ground bounce |
| 9 | 3OUT | Output of third op-amp channel - fully independent; no crosstalk with Channels 1–2 per datasheet testing |
| 10 | 3IN+ | Noninverting input of third channel - supports multi-stage filtering or signal routing |
| 11 | VCC− | Shared negative rail - all four amplifiers reference this node; layout must avoid shared impedance |
| 12 | 3IN− | Inverting input of third channel - used in active filter topologies or summing junctions |
| 13 | 4IN− | Inverting input of fourth channel - enables quad-channel simultaneous acquisition or processing |
| 14 | 4OUT | Output of fourth op-amp channel - completes full quad functionality in compact SOIC 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 |
|---|---|---|---|
| TL074CP | Dual-in-line (PDIP-14) package; identical electrical specs but higher thermal resistance (RθJA = 80°C/W vs 114°C/W for SOIC) | Preferred for prototyping and through-hole PCBs; unsuitable for high-density SMT production | Select TL074CP only when manual assembly or breadboard evaluation is required |
| OPA4134UA | Lower noise (8 nV/√Hz), lower distortion (0.00008%), rail-to-rail output, but higher quiescent current (4 mA/ch) and cost | Used in premium audio and metrology-grade instruments where noise and linearity outweigh power budget constraints | Choose OPA4134UA when sub-10 nV/√Hz noise and <0.0001% THD+N are mandatory design requirements |
Compared with TL074CP, TL074CDG4 offers superior thermal performance and SMT compatibility; compared with OPA4134UA, it trades ultra-low noise for lower power and cost-making TL074CDG4 optimal for mainstream industrial and pro-audio signal chains.

FAQ
What is the maximum supply voltage rating for TL074CDG4?
The TL074CDG4 supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V), with absolute maximum ratings of –0.3 V to +36 V on VCC+ and VCC– pins for NS and PS packages. Operation beyond ±20 V is not recommended due to increased power dissipation and potential reliability degradation. Always observe derating curves in the thermal section of the datasheet when operating near limits.
Does TL074CDG4 include internal ESD protection?
Yes, TL074CDG4 features integrated ESD protection rated at ±2000 V HBM and ±1000 V CDM per JEDEC standards. This enables robust handling during board assembly and field operation in environments with moderate electrostatic activity. However, external TVS diodes are still advised for high-risk I/O lines exposed to connectors or cables.
Can TL074CDG4 drive capacitive loads up to 300 pF stably?
Yes, TL074CDG4 is characterized to drive up to 300 pF capacitive loads while maintaining phase margin ≥56° and stable step response. This capability eliminates the need for external isolation resistors in many filter and cable-driving applications. For loads exceeding 300 pF, consider adding a small series resistor (10–50 Ω) at the output to restore stability.
What is the typical input offset voltage for TL074CDG4?
The typical input offset voltage for TL074CDG4 is ±1 mV at 25°C, with a maximum of ±4 mV under standard test conditions. Over the full 0°C to 70°C temperature range, the maximum specified offset is ±5 mV. This level of DC precision supports accurate DC-coupled gain stages in sensor interfaces and calibration circuits without trimming.
Is TL074CDG4 pin-compatible with other TL074 variants like TL074CP or TL074CN?
Yes, TL074CDG4 is pin-compatible with all TL074x variants in the 14-pin SOIC (D) package, including TL074CP (PDIP-14) and TL074CN (SOIC-14). The pinout matches Table 4-6 in the datasheet exactly: Pins 1–3, 5–7, 9–10, and 12–14 serve identical functions across all D-package versions. Mechanical footprint differs only between SOIC and PDIP, not electrical function.
