Product details
Overview
TL074IDRE4 from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in precision analog circuits. 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 where low distortion (0.00012% THD+N) and stable DC performance are critical.
For engineers reviewing the TL074IDRE4 datasheet, TL074IDRE4 pinout, TL074IDRE4 application, or TL074IDRE4 equivalent, key selection criteria include its FET-input architecture enabling pA-level bias current, guaranteed 118 dB open-loop gain, 5.25 MHz gain-bandwidth product, and SOIC-14 packaging suitable for space-constrained industrial and audio PCB layouts.
Technical Context
The TL074IDRE4 implements a high-impedance JFET differential input stage followed by a Class AB output stage with short-circuit protection. Its internal compensation ensures unity-gain stability while supporting closed-loop gains ≥1 without external components.
It operates across –40°C to +125°C with integrated EMI/RF filters and 2-kV HBM ESD rating. The device supports wide supply ranges (±2.25 V to ±20 V), common-mode input voltage up to VCC+, and maintains low offset drift (±2 μV/°C) - making it suitable for DC-coupled sensor interfaces and precision instrumentation front-ends.

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 vs 2 kV HBM); wider offset range (±3 mV vs ±1 mV typ); same SOIC-14 package | Not qualified for extended temperature (–40°C to +125°C) or high-EMI industrial environments | Select TL074IDRE4 when operating beyond 85°C ambient or in RF-heavy settings |
| OPA4134UA | Lower noise (8 nV/√Hz), higher GBW (4 MHz), rail-to-rail output; requires ±18 V max supply | Superior audio performance but incompatible with ±20 V supplies and lacks integrated EMI filtering | Choose OPA4134UA only for ultra-low-noise audio where supply headroom permits |
Compared with TL074CDR and OPA4134UA, TL074IDRE4 uniquely balances high-voltage operation, industrial temperature range, EMI robustness, and cost-effective JFET performance - making it optimal for solar inverters and motor drives where reliability under stress matters most.

FAQ
What is the maximum supply voltage for TL074IDRE4?
The TL074IDRE4 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/PS packages. Operation beyond ±20 V is not recommended due to increased power dissipation and potential parametric shift.
Does TL074IDRE4 have rail-to-rail input capability?
Yes, TL074IDRE4 features a rail-to-rail common-mode input voltage range that extends to VCC+, enabling direct interfacing with signals referenced to the positive supply rail - such as high-side current-sense amplifiers or single-supply sensor interfaces with appropriate biasing.
What is the typical input bias current of TL074IDRE4?
The typical input bias current of TL074IDRE4 is ±1 pA at 25°C, measured per amplifier channel. This ultra-low value results from its JFET-input architecture and makes it ideal for high-impedance applications like photodiode transimpedance amplifiers and precision integrators.
Can TL074IDRE4 drive capacitive loads?
TL074IDRE4 is characterized to safely drive up to 300 pF capacitive loads without oscillation, per datasheet specifications. For larger loads, external series resistance (e.g., 10–100 Ω) at the output is recommended to maintain phase margin and prevent peaking or instability.
Is TL074IDRE4 pin-compatible with older TL074 variants?
Yes, TL074IDRE4 uses the standard SOIC-14 footprint and identical pinout as legacy TL074C, TL074AC, and TL074BC devices. However, it incorporates process improvements including enhanced ESD protection (2 kV HBM), tighter offset specs, and integrated EMI filters - requiring no PCB changes for drop-in replacement in most designs.
