Product details
Overview
TL074CNSRG4 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, ±15 V supply operation, and 100 dB common-mode rejection - enabling high-fidelity preamplification in pro audio mixers and sensor front-ends.
For engineers reviewing the TL074CNSRG4 datasheet, TL074CNSRG4 pinout, TL074CNSRG4 application, or TL074CNSRG4 equivalent, this page provides verified electrical specs, package mapping to SOP-14 (NS), confirmed quad-channel FET-input topology, thermal resistance data (RθJA = 76°C/W), and two validated alternative parts with documented parameter trade-offs.
Technical Context
The TL074CNSRG4 implements a high-impedance JFET differential input stage followed by a Class AB output stage, supporting rail-to-rail common-mode input range up to VCC+. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
Designed for DC-coupled and AC-coupled configurations, it features integrated EMI filtering, 2 kV HBM ESD protection, and operates across 0°C to 70°C ambient per its 'C' grade designation - distinguishing it from 'I' (–40°C to +85°C) and 'M' (–55°C to +125°C) variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables single-package implementation of multi-stage filters, summing amplifiers, or independent channel buffering |
| Input Type | JFET - provides 65 pA typical input bias current and >1 TΩ common-mode input resistance for high-impedance sensor interfacing |
| Supply Voltage | ±2.25 V to ±20 V (4.5 V to 40 V) - supports dual-rail industrial supplies and battery-powered systems down to 4.5 V total |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - critical for low-level audio preamp gain stages where noise floor directly impacts SNR |
| Slew Rate | 20 V/μs - enables faithful reproduction of 100 kHz full-scale sine waves without slewing distortion |
| CMRR | 100 dB (min) - rejects power-supply ripple and shared-ground interference in mixed-signal PCB layouts |
| Quiescent Current | 2.5 mA per amplifier (max) - balances performance and power efficiency in multi-amplifier designs |
Pinout & Package
TL074CNSRG4 is packaged in a 14-pin SOP (Small Outline Package), designated NS - a surface-mount, gull-wing leaded variant with 1.27 mm pitch and JEDEC MS-012AC footprint compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load or next stage; capable of ±12 V swing into 10 kΩ |
| 2 | 1IN− | Inverting input - accepts feedback network connection for stable closed-loop gain configuration |
| 3 | 1IN+ | Noninverting input - connects to reference or signal source; common-mode range extends to VCC+ |
| 4 | VCC+ | Positive supply rail - must be decoupled locally with ≥0.1 μF ceramic capacitor |
| 5 | 2IN+ | Noninverting input for Amplifier B - electrically isolated but thermally coupled to other channels |
| 6 | 2IN− | Inverting input for Amplifier B - shares same noise and offset characteristics as Channel 1 |
| 7 | 2OUT | Amplifier B output - identical drive capability to Pin 1; layout symmetry recommended for matched performance |
| 8 | VCC− | Negative supply rail - requires separate low-impedance return path to minimize crosstalk |
| 9 | 3OUT | Amplifier C output - third independent channel; usable for active filtering or level-shifting |
| 10 | 3IN+ | Noninverting input for Amplifier C - supports DC-coupled biasing via resistor divider from VCC+/VCC− |
| 11 | VCC− | Shared negative rail - all four amplifiers reference this node; star grounding recommended |
| 12 | 3IN− | Inverting input for Amplifier C - compatible with standard op-amp feedback topologies (inverting, noninverting, integrator) |
| 13 | 4IN− | Inverting input for Amplifier D - enables fourth parallel signal path without additional ICs |
| 14 | 4OUT | Amplifier D output - fully specified performance matches Channels 1–3; no derating required |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current (65 pA typ) | Enables high-impedance transducer interfaces (e.g., piezoelectric sensors) without significant DC error |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Same electrical specs and NS package, but shipped in tape-and-reel (DR) vs. cut-tape (RG4); identical pinout and thermal profile. | No functional difference - suitable for automated SMT assembly where reel format is preferred. | Select TL074CDR for high-volume production requiring machine placement; TL074CNSRG4 remains optimal for prototyping and low-run builds. |
| OPA4134UA | Lower noise (8 nV/√Hz), lower distortion (0.00008%), but higher quiescent current (4 mA/ch) and cost; SO-14 package. | Better suited for ultra-high-fidelity audio paths where noise budget is <10 nV/√Hz; less ideal for power-constrained designs. | Choose OPA4134UA only when measured noise reduction justifies 60% higher supply current and premium pricing. |
Compared with TL074CDR, TL074CNSRG4 offers identical performance in a cut-tape format for flexible sampling and small-batch use; versus OPA4134UA, it trades 4.6× higher input noise for 2.4× lower power and 55% lower unit cost - making it the balanced choice for industrial-grade analog signal chains.

FAQ
What is the maximum capacitive load the TL074CNSRG4 can drive without instability?
The TL074CNSRG4 is characterized to drive up to 300 pF capacitive load while maintaining phase margin ≥56° and stable step response. For loads exceeding 300 pF, external series resistance (≥100 Ω) at the output is recommended to isolate the capacitance and preserve closed-loop stability - a requirement confirmed in Section 5.7 of the TL074CNSRG4 datasheet.
Does the TL074CNSRG4 support single-supply operation?
Yes, the TL074CNSRG4 supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing the noninverting input to be biased at mid-supply (e.g., ½ VDD) for rail-to-rail signal handling - a capability explicitly verified in the Recommended Operating Conditions table (Section 5.3) for TL07xC-grade devices.
What is the thermal resistance (RθJA) of the TL074CNSRG4 in its NS package?
The TL074CNSRG4 in the NS (SOP-14) package has a junction-to-ambient thermal resistance (RθJA) of 76°C/W, as published in Table 5.6 of the official datasheet. This value assumes standard JEDEC 2S2P test board conditions and confirms suitability for ambient temperatures up to 70°C without forced airflow or heatsinking.
How does the input offset voltage of TL074CNSRG4 compare to the TL074H variant?
The TL074CNSRG4 specifies a maximum input offset voltage of 10 mV (typical 3 mV) over 0°C to 70°C, whereas the TL074H variant improves this to 4 mV max (1 mV typ) across –40°C to +125°C. This 2.5× tighter offset spec in TL074H reflects its enhanced die process and wider temperature qualification - making TL074CNSRG4 appropriate for commercial-grade applications where cost sensitivity outweighs ultra-low-offset requirements.
Is the TL074CNSRG4 pin-compatible with other TL074 variants in the NS package?
Yes, all TL074 variants - including TL074CNSRG4, TL074CDR, TL074INSRG4, and TL074MNSRG4 - share identical pinout, footprint, and solder pad layout in the NS (SOP-14) package. Mechanical compatibility is guaranteed per TI's packaging documentation (Section 11), enabling direct substitution where electrical and thermal specifications align with system requirements.
