Product details
Overview
TL074HIPWR from Texas Instruments is a quad-channel, low-noise, JFET-input operational amplifier optimized for high-slew-rate precision signal conditioning in industrial and audio systems. It delivers 20 V/μs slew rate, 1 mV typical input offset voltage, 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 used in pro audio mixers and battery test equipment where low distortion (0.00012% THD+N) and EMI robustness are critical.
For engineers reviewing the TL074HIPWR datasheet, TL074HIPWR pinout, TL074HIPWR application, or TL074HIPWR equivalent, key selection factors include its FET-input architecture enabling pA-level bias current, wide supply flexibility, integrated EMI/RF filtering, and guaranteed operation from –40°C to +125°C - all validated for rugged embedded analog front-ends requiring stable DC accuracy and dynamic linearity.
Technical Context
The TL074HIPWR implements a fully differential JFET-input stage with cascoded gain and class-AB output stage, supporting unity-gain-stable operation with up to 300 pF capacitive load drive. Its internal EMI/RF filters suppress interference at 1 GHz (53 dB EMIRR), while the high-impedance input (6 TΩ common-mode, 100 MΩ differential) minimizes loading on high-Z sensor sources.
It features rail-inclusive common-mode input range (VCM includes VCC+), output short-circuit protection, and thermal shutdown. The device uses TI's modern H-suffix die fabricated on an enhanced process, delivering improved offset drift (±2 μV/°C) and lower quiescent current (940 μA/ch typ) versus legacy TL074 variants.

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 | Legacy C-grade (0°C to 70°C), higher 3 mV max offset, 37 nV/√Hz noise unchanged, no integrated EMI filters | Limited to commercial-temperature consumer electronics; unsuitable for industrial or automotive environments | Select TL074CDR only for cost-sensitive, non-ruggedized applications where extended temperature and EMI immunity are not required |
| OPA4134UA | Lower 0.5 mV max offset, 8 nV/√Hz noise, 20 V/μs slew rate, ±13.5 V output swing, no EMI filtering | Better DC precision and noise performance, but lacks 1 GHz EMI rejection and extended temp rating | Choose OPA4134UA for ultra-low-noise audio or medical instrumentation where EMI is controlled, but avoid in noisy industrial settings |
Compared with TL074CDR, TL074HIPWR adds –40°C to +125°C operation, EMI filtering, and tighter offset drift - making it superior for harsh environments; versus OPA4134UA, it trades some noise performance for ruggedness and integrated interference suppression.

FAQ
What is the maximum supply voltage for TL074HIPWR?
The TL074HIPWR supports a total supply voltage (VCC+ to VCC–) of up to 40 V (±20 V). Absolute maximum ratings specify 42 V for most packages, but recommended operating conditions limit continuous use to 40 V to ensure long-term reliability and specified performance across –40°C to +125°C. Exceeding 40 V may degrade offset drift or noise specifications.
Does TL074HIPWR require external offset nulling components?
No, TL074HIPWR does not provide offset null pins and is not designed for external trimming. Its H-suffix variant achieves ±1 mV typical input offset voltage and ±2 μV/°C drift through process enhancements, eliminating the need for manual calibration in most applications. For ultra-precision use cases demanding sub-100 μV offset, consider auto-zero alternatives like OPA4188.
Can TL074HIPWR drive capacitive loads up to 300 pF?
Yes, TL074HIPWR is characterized to drive up to 300 pF capacitive loads while maintaining stability and specified settling time (0.63 μs to 0.1%). This capability is verified in the datasheet's Electrical Characteristics table under "Capacitive load drive". Layout best practices - such as minimizing trace length and using local decoupling - remain essential to preserve phase margin.
How does TL074HIPWR differ from standard TL074 variants?
TL074HIPWR belongs to the H-suffix family, featuring TI's modern die with integrated EMI/RF filters (53 dB rejection at 1 GHz), improved offset drift (±2 μV/°C vs ±18 μV/°C in C-grade), lower quiescent current (940 μA/ch vs 1.4 mA/ch), and guaranteed operation from –40°C to +125°C. It retains the same pinout and core architecture as legacy TL074 but delivers enhanced robustness for demanding industrial deployments.
Is TL074HIPWR suitable for single-supply operation?
Yes, TL074HIPWR supports true single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing input signals referenced to ground or mid-rail without level-shifting circuitry. However, output swing is not rail-to-rail - expect ~210 mV headroom to each rail at 40 V supply - so design margins must account for this limitation in low-voltage applications.
