Texas Instruments TL072CPS

Overview

TL072CPS 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 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 TL072CPS datasheet, TL072CPS pinout, TL072CPS application, or TL072CPS equivalent, this page provides verified specifications, SO package terminal mapping, real-world use cases in audio and test instrumentation, and validated alternative parts with documented functional and thermal differences.

Technical Context

The TL072CPS uses a dual JFET-input stage enabling ultra-low input bias current (≤200 pA) and high input impedance (>1 TΩ), making it suitable for high-source-impedance sensor interfaces. Its internal compensation ensures stable unity-gain operation with ≤20 pF capacitive load.

It features fully differential input architecture with common-mode rejection of 90–105 dB and power-supply rejection of 70–100 dB, supporting robust performance across ±4.5 V to ±20 V supplies and 0°C to +70°C ambient operation.

FAQ

What is the operating temperature range for TL072CPS?

The TL072CPS is specified for operation from 0°C to +70°C ambient temperature. This commercial-grade rating makes it suitable for indoor audio equipment, benchtop test instruments, and non-automotive industrial control applications where extended temperature tolerance is not required. The "C" suffix explicitly denotes this temperature grade, distinguishing it from the "I" (–40°C to +85°C) and "M" (–55°C to +125°C) variants. Always verify thermal derating in high-power-density layouts.

Does TL072CPS support single-supply operation?

Yes, TL072CPS supports single-supply operation within its specified voltage range of 4.5 V to 40 V total supply (e.g., 0 V and +15 V). Its common-mode input range extends to the positive rail (VCC+), allowing input signals referenced to ground. However, output swing does not reach the negative rail-minimum headroom is ~105 mV-so proper input biasing and output coupling (e.g., AC coupling or level-shifting) is required for true rail-to-rail signal handling in single-supply configurations.

What is the maximum capacitive load TL072CPS can drive stably?

TL072CPS is characterized for stable operation with up to 300 pF capacitive load under unity-gain conditions, as confirmed in Section 5.7 of the datasheet. Driving larger loads (e.g., long cables or ADC input capacitance >300 pF) risks peaking or oscillation; a series isolation resistor (typically 20–100 Ω) between the output and load is recommended to restore phase margin. This capability supports direct connection to most SAR and sigma-delta ADCs without external buffering.

How does TL072CPS compare to TL072H in noise performance?

TL072CPS and TL072H share identical input voltage noise density: 37 nV/√Hz at 1 kHz. Both versions meet the same low-noise specification because the "C" and "H" suffixes denote different process generations and temperature grades-not noise optimization tiers. The H-version adds enhanced ESD protection (1.5 kV HBM) and extended temperature range (–40°C to +125°C), but noise, slew rate, and offset voltage distributions remain consistent across the TL072x family for equivalent test conditions.

Is TL072CPS pin-compatible with other dual op-amps in SOIC-8 packages?

TL072CPS follows the industry-standard dual op-amp pinout (Pin 1 = Amp A out, Pin 2 = Amp A in−, Pin 3 = Amp A in+, Pin 4 = V−, Pin 5 = Amp B in+, Pin 6 = Amp B in−, Pin 7 = Amp B out, Pin 8 = V+) and is mechanically and electrically pin-compatible with TL072CDR, TL072IP, NE5532, and RC4558 in SOIC-8. However, electrical behavior-including input stage type, noise, and slew rate-differs significantly; direct substitution requires validation of bias current, noise, and stability in the target circuit.
