Texas Instruments TL071CDRE4

Overview

TL071CDRE4 from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 37 nV/√Hz input voltage noise at 1 kHz, 20 V/μs slew rate, ±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 high fidelity and DC accuracy are critical.

For engineers reviewing the TL071CDRE4 datasheet, TL071CDRE4 pinout, TL071CDRE4 application, or TL071CDRE4 equivalent, key selection considerations include its FET-input architecture for ultra-low input bias current (±1 pA typ), offset voltage drift of ±2 μV/°C, 5.25 MHz gain-bandwidth product, and SOIC-8 package compatibility with legacy TL071 designs requiring stable DC performance and wide supply flexibility.

Technical Context

The TL071CDRE4 implements a high-impedance JFET differential input stage followed by a Class AB output stage, enabling low input bias current and high open-loop gain (125 dB typ). Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.

It supports dual-supply operation from ±2.25 V to ±20 V (or single-supply 4.5 V to 40 V), features EMI/RF filtering, and operates across –40°C to +85°C - matching the TL071C temperature grade. Input common-mode range includes VCC+, allowing direct sensing of signals near the positive rail.

FAQ

What is the maximum supply voltage rating for TL071CDRE4?

The TL071CDRE4 supports a total supply voltage (VCC+ − VCC−) of up to 40 V, corresponding to ±20 V dual supply or 4.5 V to 40 V single supply. Absolute maximum ratings specify 42 V for non-NS/PS packages, but TI recommends staying within 40 V for reliable operation per Section 5.1 of the datasheet. Exceeding this may cause permanent damage or accelerated parametric shift.

Does TL071CDRE4 have rail-to-rail input or output capability?

The TL071CDRE4 features rail-to-rail input common-mode range - specifically, it includes VCC+ - but does not provide rail-to-rail output swing. Its output typically swings within 210 mV of VCC+ and 215 mV of VCC− under 10 kΩ load. This makes it suitable for high-side sensing but requires headroom-aware design for output interfacing.

Can TL071CDRE4 replace older TL071 variants like TL071CP on the same PCB?

Yes, TL071CDRE4 is pin-compatible with TL071CP in SOIC-8 vs PDIP-8 footprints only if the PCB is redesigned for SOIC-8. Electrically, it matches TL071C specifications (e.g., 3–10 mV offset, 5.25 MHz GBW), but adds integrated EMI filtering and improved thermal resistance (158.8°C/W vs 85°C/W). No circuit changes are needed beyond footprint adaptation.

What is the input offset voltage specification for TL071CDRE4 at room temperature?

The TL071CDRE4 has a maximum input offset voltage of 10 mV at TA = 25°C, with typical value of 3 mV. This is specified under TL071C grade conditions (VS = ±15 V, RL = 10 kΩ) per Section 5.8 of the datasheet. The "C" suffix denotes commercial temperature range (0°C to 70°C), and offset remains ≤13 mV across full operating range.

Is TL071CDRE4 suitable for single-supply operation?

Yes, TL071CDRE4 supports true single-supply operation from 4.5 V to 40 V. Its input common-mode range includes the positive rail (VCC+), enabling high-side signal conditioning without level shifting. However, output swing remains limited - designers must bias inputs mid-supply and verify headroom for intended load and gain configuration.
