Texas Instruments TL072CDRE4

Overview

TL072CDRE4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise audio and precision signal conditioning. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V supply range, and operates across 0°C to 70°C. It is widely used in pro audio mixers and battery test equipment where high CMRR and rail-to-rail common-mode input (including VCC+) are critical.

For engineers reviewing the TL072CDRE4 datasheet, TL072CDRE4 pinout, TL072CDRE4 application, or TL072CDRE4 equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±120 pA typ), dual-channel SOIC-8 packaging, 5.25 MHz gain-bandwidth product, and compatibility with single-supply or split-supply configurations up to 40 V total.

Technical Context

The TL072CDRE4 implements a high-slew-rate JFET differential input stage followed by a Class AB output stage with short-circuit protection. Its input stage supports common-mode voltage up to VCC+, enabling true single-supply operation without level-shifting circuitry.

It features integrated EMI/RF filters and 2 kV HBM ESD rating, supporting robust performance in electrically noisy environments such as motor drive feedback loops and UPS control circuits. The device uses the legacy TL07x "C" grade silicon (not the newer "H" variant), with offset voltage of 3–10 mV and drift of ±18 µV/°C over temperature.

Key Specifications

Pinout & Package

TL072CDRE4 is housed in an 8-pin SOIC (D) package with standard industry footprint and 1.27 mm pitch. Pin 1 is marked by a beveled corner or dot; the package is RoHS-compliant and moisture-sensitive level 1.

FAQ

What is the maximum supply voltage for TL072CDRE4?

The TL072CDRE4 supports a total supply voltage range of 4.5 V to 40 V (±2.25 V to ±20 V). Absolute maximum ratings specify 42 V for non-NS/PS packages, but recommended operation limits to 40 V to ensure reliability and maintain specified performance across temperature. Exceeding 40 V may degrade long-term parametric stability.

Does TL072CDRE4 have rail-to-rail input or output capability?

TL072CDRE4 features rail-to-rail input common-mode range - specifically, the input can swing up to VCC+ - but does not offer rail-to-rail output. Its output swing is limited to approximately 115–210 mV from the positive rail and 105–215 mV from the negative rail under 10 kΩ load, per datasheet Section 5.7.

Is TL072CDRE4 pin-compatible with other TL072 variants?

Yes, TL072CDRE4 is pin-compatible with all TL072x variants in the SOIC-8 (D) package, including TL072IDR, TL072CDR, and TL072ACDR. Pin functions and physical layout match exactly; differences lie only in temperature grade, offset voltage distribution, and ESD robustness - not pin assignment or electrical interface.

What is the typical input offset voltage for TL072CDRE4?

The typical input offset voltage for TL072CDRE4 is 3 mV at 25°C, with a guaranteed maximum of 10 mV across the full 0°C to 70°C operating range. This value reflects the "C" grade specification per Section 5.8 of the datasheet, distinct from tighter "A" or "B" grades.

Can TL072CDRE4 drive capacitive loads directly?

TL072CDRE4 is characterized to safely drive up to 300 pF capacitive load without oscillation, per Section 5.7. For larger loads (e.g., cables or ADC input capacitance), external isolation resistance (e.g., 100 Ω in series with output) is recommended to maintain phase margin and prevent peaking or instability.
