Texas Instruments TL072CPE4

Overview

TL072CPE4 from Texas Instruments is a dual 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, ±15 V supply operation, and 100 dB common-mode rejection - enabling high-fidelity preamplification in pro audio mixers and sensor front-ends.

For engineers reviewing the TL072CPE4 datasheet, TL072CPE4 pinout, TL072CPE4 application, or TL072CPE4 equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (65 pA typ), rail-to-rail input common-mode range extending to VCC+, and dual-channel configuration supporting stereo or differential signal paths without crosstalk degradation.

Technical Context

The TL072CPE4 implements a two-stage JFET differential input stage followed by a Class-A gain stage and push-pull output stage, delivering high open-loop gain (200 V/mV) with stable unity-gain compensation. Its input stage features matched P-channel JFETs providing symmetrical bias current and low offset drift (±18 µV/°C).

It operates across 0°C to 70°C ambient temperature with ±2.25 V to ±20 V dual-supply capability (4.5 V to 40 V single-supply), supports capacitive loads up to 300 pF, and includes internal short-circuit protection on both outputs - making it suitable for robust industrial transducer interfaces and battery-powered instrumentation.

FAQ

What is the operating temperature range for TL072CPE4?

The TL072CPE4 is rated for operation from 0°C to +70°C ambient temperature, consistent with its 'C' grade designation. This commercial-grade specification makes it suitable for indoor consumer and industrial equipment where environmental extremes are not expected. The device maintains specified offset voltage (≤10 mV), slew rate (≥8 V/μs), and CMRR (≥70 dB) across this full range.

Does TL072CPE4 support single-supply operation?

Yes, TL072CPE4 supports single-supply operation from 4.5 V to 40 V. Its input common-mode range extends to the positive rail (VCC+), enabling direct interface with ground-referenced sensors without level-shifting circuitry. For optimal performance, the output swing remains within 1.2 V of each rail under 2 kΩ load, and input biasing must establish a proper DC operating point - typically via resistor dividers or dedicated reference ICs.

How does TL072CPE4 compare to TL072H in noise performance?

TL072CPE4 specifies 37 nV/√Hz input voltage noise density at 1 kHz, identical to the TL072H variant. Both share the same JFET input stage topology and noise characteristics; the 'C' and 'H' suffixes denote different process generations and temperature grades (C: 0°C–70°C; H: –40°C–125°C), not noise differentiation. The 37 nV/√Hz value is confirmed in Section 5.9 of the datasheet for TL07xC devices under standard test conditions.

Can TL072CPE4 drive capacitive loads?

Yes, TL072CPE4 can safely drive capacitive loads up to 300 pF without oscillation, as specified in its Electrical Characteristics table. This capability supports direct connection to coaxial cables, ADC input filters, and long PCB traces. For loads exceeding 300 pF, external isolation resistance (e.g., 100 Ω in series with the output) is recommended to maintain phase margin above 56° and prevent peaking or instability.

What is the purpose of the NC pins on TL072CPE4?

TL072CPE4 has no NC (No Connect) pins - all eight pins in its PDIP-8 package are functional: Pins 1/7 (outputs), 2/3/5/6 (inputs), and 4/8 (power rails). Unlike some variants (e.g., TL071C PS package with offset null pins), the TL072CPE4 uses a minimal pinout optimized for dual-channel operation without auxiliary functions. This eliminates unused terminals that could introduce parasitic coupling or layout complexity.
