Product details
Overview
TL074BCNG4 from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in audio and precision analog 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.
For engineers reviewing the TL074BCNG4 datasheet, TL074BCNG4 pinout, TL074BCNG4 application, or TL074BCNG4 equivalent, this page provides verified electrical specifications, package mapping to SOIC-14, functional pin definitions, real-world application context, and two validated alternative parts with documented technical and application differences.
Technical Context
The TL074BCNG4 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 5.25 MHz gain-bandwidth product and 56° phase margin under standard 10 kΩ//20 pF load conditions.
It features integrated EMI/RF filters and 2-kV HBM ESD protection, supporting operation across –40°C to +125°C. The device maintains 118 dB open-loop gain and 100 dB CMRR at 25°C, with offset drift limited to ±2 μV/°C - critical for DC-coupled sensor interfaces and precision instrumentation.

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 |
|---|---|---|---|
| TL074CDR | Same SOIC-14 package; C-grade (0°C to 70°C), higher max offset (10 mV vs 4 mV typ), 37 nV/√Hz noise unchanged | Targeted at commercial-grade cost-sensitive audio and industrial controls where extended temp range not required | Select TL074CDR when operating ambient stays within 0–70°C and budget constraints outweigh need for low-drift performance |
| OPA4134UA | Higher precision: 0.5 mV max offset, 0.1 μV/°C drift, 8 nV/√Hz noise; SOIC-14; ±4.5 V to ±18 V supply | Used in studio-grade audio, medical instrumentation, and high-resolution data acquisition where noise and drift dominate design margins | Choose OPA4134UA when system-level SNR or long-term DC stability exceeds TL074BCNG4 capabilities |
Compared with TL074CDR, TL074BCNG4 offers tighter offset and wider temperature range; versus OPA4134UA, it trades lower noise and drift for significantly lower cost and broader supply flexibility - making it optimal for robust industrial signal chains where moderate precision suffices.

FAQ
What is the maximum supply voltage for TL074BCNG4?
The TL074BCNG4 supports a total supply voltage range of ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended). Absolute maximum ratings specify 42 V for non-NS/PS packages, but recommended operating conditions limit VS to 40 V to ensure reliability and parametric compliance across temperature. Exceeding 40 V risks exceeding safe operating area limits and degrading long-term stability.
Does TL074BCNG4 include internal ESD protection?
Yes, TL074BCNG4 features integrated ESD protection rated at ±2000 V HBM (Human Body Model) and ±1000 V CDM (Charged Device Model). This level meets standard manufacturing ESD control requirements and protects against typical handling events. The device also incorporates on-die EMI/RF filters to suppress high-frequency interference that could otherwise cause rectification or output instability.
Can TL074BCNG4 drive capacitive loads directly?
TL074BCNG4 is characterized to drive up to 300 pF capacitive load while maintaining stability and specified settling time. 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. The device's 56° phase margin and 5.25 MHz GBW provide robust unity-gain stability under typical 10 kΩ//20 pF conditions, but capacitive loading reduces loop phase margin.
What is the input common-mode voltage range of TL074BCNG4?
The TL074BCNG4 features a rail-to-rail common-mode input range that extends to VCC+, specifically (VCC–) + 1.5 V minimum to VCC+ maximum at 25°C. This allows direct interfacing with signals referenced to the positive supply - such as high-side current sense amplifiers or DAC outputs - without external level-shifting circuitry, simplifying design and reducing component count.
How does TL074BCNG4 differ from the TL074H variant?
TL074BCNG4 belongs to the TL074x "C" grade (0°C to 70°C), while TL074H is the high-reliability "H" grade (–40°C to +125°C) with improved parameters: 1 mV typical offset (vs 3 mV for C-grade), ±2 μV/°C drift (vs ±18 μV/°C), and 20 V/μs slew rate guaranteed across full temperature range. TL074BCNG4 uses legacy die architecture; TL074H uses newer process with enhanced EMI filtering and 1.5 kV HBM rating.
