Product details
Overview
TL074HIDYYR from Texas Instruments is a quad-channel, low-noise, JFET-input operational amplifier optimized for high-fidelity audio and precision analog signal conditioning. 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 wide bandwidth are critical.
For engineers reviewing the TL074HIDYYR datasheet, TL074HIDYYR pinout, TL074HIDYYR application, or TL074HIDYYR equivalent, this page provides verified specifications, package-validated pin functions, real-world use scenarios, and two confirmed alternative parts with documented technical and application differences-enabling confident selection for audio front-ends, sensor signal chains, and industrial instrumentation.
Technical Context
The TL074HIDYYR implements a JFET-input differential pair with high-impedance, low-bias-current inputs (±1 pA typical), enabling accurate amplification of high-source-impedance signals without loading. Its internal compensation ensures stable unity-gain operation with up to 300 pF capacitive load drive.
It features integrated EMI/RF filters and 2-kV HBM ESD protection, supporting robust operation in electrically noisy environments like motor drive feedback loops and solar inverter monitoring circuits across –40°C to +125°C.

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 | Lower ESD rating (1.5 kV HBM vs 2 kV), wider offset voltage (±3 mV typ), no integrated EMI filters | Rated only for 0°C to 70°C; unsuitable for automotive or extended-temperature industrial use | Select when cost sensitivity outweighs EMI immunity and temperature range requirements |
| OPA4134UA | Lower noise (8 nV/√Hz), lower THD+N (0.00008%), higher quiescent current (4 mA/ch), no short-circuit protection | Optimized for ultra-low-distortion audio; lacks robustness for industrial fault conditions | Select for premium audio DAC output stages where absolute lowest noise and distortion are prioritized |
Compared with TL074CDR and OPA4134UA, the TL074HIDYYR uniquely combines high-speed performance, integrated EMI rejection, extended temperature operation, and fault protection - making it the preferred choice for ruggedized instrumentation and industrial power electronics where reliability and signal fidelity must coexist.

FAQ
What is the maximum capacitive load the TL074HIDYYR can drive stably?
The TL074HIDYYR is characterized to drive up to 300 pF capacitive load while maintaining phase margin ≥56° and stable unity-gain operation. This specification is validated per TI's datasheet Section 5.7 under G = +1, RL = 10 kΩ, and CL = 20–300 pF. For loads exceeding 300 pF, external isolation resistors or gain adjustment may be required to prevent peaking or oscillation in the TL074HIDYYR output stage.
Does the TL074HIDYYR support single-supply operation?
Yes, the TL074HIDYYR supports true single-supply operation from 4.5 V to 40 V. Its common-mode input voltage range extends to VCC+, and output swing reaches within 115 mV of the positive rail (at 10 kΩ load). When operated single-ended, VCC– should be connected to ground, and input signals must remain within (VCC–)+1.5 V to VCC+ to avoid clipping or increased distortion in the TL074HIDYYR.
What is the guaranteed input offset voltage drift over temperature for TL074HIDYYR?
The TL074HIDYYR has a maximum input offset voltage drift of ±2 μV/°C across the full operating temperature range of –40°C to +125°C, as specified in TI's datasheet Section 5.7. This tight drift spec ensures predictable DC error accumulation in precision integrators, thermocouple amplifiers, and other temperature-sensitive analog circuits using the TL074HIDYYR.
How does the EMI rejection ratio of TL074HIDYYR compare to standard TL074 variants?
The TL074HIDYYR provides 53 dB EMI rejection ratio at 1 GHz, a feature not present in legacy TL074C/D/I/M variants. This performance stems from integrated on-die EMI/RF filters - explicitly added to the "H"-suffix die revision - which suppress high-frequency interference without requiring external ferrite beads or RC networks in the TL074HIDYYR signal path.
Is the TL074HIDYYR pin-compatible with other TL074 package variants?
Yes, the TL074HIDYYR uses the standard 14-pin SOT-23-THIN (DYY) footprint defined in TI's packaging documentation, matching pinout and function with all TL074x DYY variants. Pin assignments - including VCC+, VCC–, and all four amplifier inputs/outputs - are identical across the TL074H, TL074A, TL074B, and TL074M families in the DYY package, ensuring drop-in replacement capability in existing TL074HIDYYR-compatible layouts.
