Texas Instruments TL072BCDE4

Overview

TL072BCDE4 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 –40°C to +125°C. It is used in pro audio mixers and battery test equipment where high CMRR (105 dB), low offset drift (2 μV/°C), and rail-to-rail common-mode input (including VCC+) are critical.

For engineers reviewing the TL072BCDE4 datasheet, TL072BCDE4 pinout, TL072BCDE4 application, or TL072BCDE4 equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±1 pA typ), dual-channel SOIC-8 packaging, guaranteed performance over extended temperature, and compatibility with single-supply and split-supply configurations in analog front-ends.

Technical Context

The TL072BCDE4 implements a two-stage JFET-input op-amp topology with high-impedance differential pair inputs and Class AB output stage. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF and provides 56° phase margin at G = +1 with 10 kΩ load and 20 pF capacitance.

It supports wide common-mode input voltage range extending to VCC+, enabling direct sensing of signals near the positive rail-critical in single-supply instrumentation. The device integrates EMI/RF filters and achieves 1.5 kV HBM ESD rating, making it suitable for industrial environments with electrical noise.

FAQ

What is the maximum supply voltage for TL072BCDE4?

The TL072BCDE4 supports a total supply voltage (VCC+ to 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 long-term operation per the Recommended Operating Conditions table.

Does TL072BCDE4 have rail-to-rail input or output capability?

TL072BCDE4 features rail-to-rail common-mode input range-including VCC+-but does not provide rail-to-rail output swing. Its output typically swings within ~115 mV of VCC+ and ~105 mV of VCC– under 10 kΩ load. For true rail-to-rail output, consider alternatives like the OPA2340 or TLV2462.

Is TL072BCDE4 suitable for single-supply operation?

Yes, TL072BCDE4 is fully compatible with single-supply operation due to its common-mode input voltage range extending to VCC+. When used with a single supply, bias the inputs at mid-rail (e.g., via resistor divider) and ensure output load remains within the specified headroom limits relative to both rails.

What is the input bias current specification for TL072BCDE4?

The input bias current for TL072BCDE4 is ±1 pA typical at 25°C, with a maximum of ±120 pA across –40°C to +125°C. This ultra-low value stems from its JFET-input architecture and enables high-impedance applications such as piezoelectric sensor amplifiers and photodiode transimpedance stages without significant DC error.

How does TL072BCDE4 differ from the standard TL072CP?

TL072BCDE4 is the B-grade (±4 mV max offset), extended-temperature (–40°C to +125°C), SOIC-8 variant with enhanced ESD (1.5 kV HBM) and integrated EMI filtering. TL072CP is the C-grade (0°C to 70°C), PDIP-8 version with looser offset (±10 mV) and no EMI hardening-making TL072BCDE4 superior for industrial and automotive-adjacent applications.
