Texas Instruments TL072IDRE4

Overview

TL072IDRE4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, and ±1 mV typical input offset voltage across –40°C to +125°C. Used in pro audio mixers and battery test equipment where high CMRR (105 dB), rail-to-rail common-mode input (including VCC+), and low THD+N (0.00012%) are critical.

For engineers reviewing the TL072IDRE4 datasheet, TL072IDRE4 pinout, TL072IDRE4 application, or TL072IDRE4 equivalent, this page provides verified electrical specs, SOIC-8 package details, real-world use cases in audio and power electronics, and validated alternative options with documented functional trade-offs.

Technical Context

The TL072IDRE4 implements a dual-channel, high-slew-rate JFET-input op-amp architecture with integrated EMI/RF filters and 1.5-kV HBM ESD protection. Its input stage uses matched JFET pairs to achieve ultra-low input bias current (±1 pA typ) and low offset drift (±2 μV/°C).

It supports wide supply operation from ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended), features output short-circuit protection, and maintains stable unity-gain performance with up to 300 pF capacitive load-enabling direct driving of cables and ADC inputs without external isolation.

Key Specifications

Pinout & Package

TL072IDRE4 is supplied in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Pin 1 is marked by a beveled corner or dot; device orientation follows TI's standard top-view labeling.

FAQ

What is the maximum capacitive load the TL072IDRE4 can drive stably?

The TL072IDRE4 is characterized to drive up to 300 pF capacitive load while maintaining phase margin ≥56° in unity-gain configuration with 10 kΩ load. For larger loads (e.g., >500 pF), external series resistance (≥100 Ω) at the output is recommended to prevent peaking or oscillation-verified per Figure 5-23 and 5-24 in the SLOS080W datasheet.

Does the TL072IDRE4 support single-supply operation?

Yes, the TL072IDRE4 supports true single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, enabling direct interfacing with sensors referenced to the positive rail. However, output swing is limited to ~210 mV from each rail under 10 kΩ load-so mid-supply biasing (e.g., VCC/2 reference) is required for AC-coupled signals.

How does the TL072IDRE4 differ from the legacy TL072CP?

The TL072IDRE4 is the H-suffix "next-generation" variant with improved specifications: lower typical input offset voltage (±1 mV vs ±3 mV), lower input voltage noise (37 nV/√Hz vs 18 nV/√Hz only in PS/NS packages), enhanced ESD rating (1.5 kV HBM), and guaranteed operation from –40°C to +125°C. It also integrates EMI/RF filters absent in the CP version.

Is the TL072IDRE4 pin-compatible with other dual op-amps in SOIC-8?

Yes, the TL072IDRE4 uses industry-standard SOIC-8 pinout (Pin 1 = OUT A, Pin 2 = IN– A, Pin 3 = IN+ A, Pin 4 = V–, Pin 5 = IN+ B, Pin 6 = IN– B, Pin 7 = OUT B, Pin 8 = V+), matching TL072, TL082, NE5532, and OPA2134. However, differences in input structure (JFET vs bipolar), noise, and supply range require verification of circuit compatibility before drop-in replacement.

What is the quiescent current per channel for the TL072IDRE4?

The TL072IDRE4 draws 937.5 µA to 1125 µA per amplifier at 25°C (typical 940 µA), increasing to ≤1130 µA across –40°C to +125°C. This low power consumption enables dual-channel precision amplification in thermally constrained spaces such as densely packed inverter control boards or portable test gear.
