Product details
Overview
TL072CPSRE4 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, and ±15 V supply operation with rail-to-rail output swing capability up to ±13.5 V into 10 kΩ - widely used in pro audio mixers and battery test equipment.
For engineers reviewing the TL072CPSRE4 datasheet, TL072CPSRE4 pinout, TL072CPSRE4 application, or TL072CPSRE4 equivalent, this page provides verified electrical specifications, SO package terminal mapping, real-world use cases in audio and power test systems, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TL072CPSRE4 implements a high-impedance JFET differential input stage followed by a Class AB output stage, enabling ultra-low input bias current (≤200 pA) and wide common-mode range extending to VCC+. Its internal compensation ensures stable unity-gain operation with ≤20 pF capacitive load.
Designed for DC-coupled and AC-coupled amplification, it supports single-supply (4.5–40 V) and split-supply (±2.25 V to ±20 V) configurations, with input offset voltage drift of ±18 µV/°C and open-loop gain ≥100 dB across 0°C to 70°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±20 V or 4.5 V to 40 V - supports both bipolar and single-ended rails in industrial and audio systems |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - enables clean amplification of low-level sensor or microphone signals without added noise floor |
| Slew Rate | 20 V/μs - preserves transient fidelity in audio line drivers and fast-settling instrumentation stages |
| Input Offset Voltage | 3–10 mV (typ) - sufficient for non-critical DC amplification; not suited for µV-level precision sensing |
| Common-Mode Input Range | Includes VCC+ - allows direct interface with high-side sensors and rail-referenced signal sources |
| Quiescent Current | 1.4–2.5 mA per channel - balances low power consumption with performance in portable and mains-powered gear |
| Gain-Bandwidth Product | 5.25 MHz - supports stable closed-loop gains up to ~100× at audio frequencies with margin |
Pinout & Package
TL072CPSRE4 is housed in an 8-pin SO (Small Outline) package (PS), measuring 4.9 mm × 3.9 mm × 1.75 mm, with gull-wing leads and standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 | Low-impedance buffered output capable of sourcing/sinking ±26 mA; requires external load or feedback network |
| 2 | Inverting Input of Amplifier 1 | Differential input node with 1 TΩ common-mode resistance; connects to feedback path in inverting configurations |
| 3 | Noninverting Input of Amplifier 1 | High-impedance reference node; ties to ground, reference voltage, or sensor in noninverting topologies |
| 4 | Negative Supply (VCC−) | Power return for dual supplies or ground reference in single-supply operation; must be decoupled |
| 5 | Noninverting Input of Amplifier 2 | Independent second-channel input; shares no internal coupling with Channel 1 |
| 6 | Inverting Input of Amplifier 2 | Second-channel inverting node; used for summing, differential, or inverting gain stages |
| 7 | Output of Amplifier 2 | Independent output; electrically isolated from Channel 1 except via shared supply rails |
| 8 | Positive Supply (VCC+) | Main power rail; accepts up to +40 V or +20 V in split mode; requires local 0.1 µF ceramic bypass |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ≤200 pA enables high-impedance sensor interfacing (e.g., piezoelectric transducers, pH electrodes) without significant DC error |
| Output Short-Circuit Protection | Internal current limiting prevents latch-up or destruction during accidental output shorts to rail or ground |
| Wide Supply Range | Operates from ±2.25 V to ±20 V - accommodates legacy ±15 V systems and modern low-voltage embedded designs |
| Low Total Harmonic Distortion | 0.003% at 1 kHz - preserves signal integrity in audio preamplifiers and line-level signal chains |
| EMI/RF Immunity | Integrated filtering rejects 1 GHz RF interference - critical in noisy industrial environments and switch-mode power supply proximity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Same SO-8 package, identical electrical specs, but rated for 0°C to 70°C (commercial temp grade) | No extended temperature validation; unsuitable for automotive or industrial ambient extremes | Select when cost sensitivity outweighs extended temperature requirements and full traceability is not mandated |
| OPA2134PA | Lower noise (8 nV/√Hz), lower distortion (0.00008%), higher quiescent current (4 mA/ch), DIP-8 package | Higher precision audio and measurement roles where noise floor and THD dominate over power budget | Choose when upgrading from TL072CPSRE4 for studio-grade audio or metrology-grade instrumentation |
Compared with TL072CDR, TL072CPSRE4 offers full production traceability and TI's PS package qualification; versus OPA2134PA, it trades 4.6× higher noise and 37.5× lower THD for 2.8× lower supply current and broader legacy compatibility.

FAQ
What is the maximum supply voltage for TL072CPSRE4?
The TL072CPSRE4 supports a total supply voltage range of 4.5 V to 40 V (single supply) or ±2.25 V to ±20 V (dual supply). Absolute maximum ratings specify 42 V for non-PS/NS packages, but recommended operation limits to 40 V to ensure reliability and parameter stability across temperature.
Does TL072CPSRE4 have rail-to-rail output capability?
No, TL072CPSRE4 does not feature rail-to-rail output. Its output swing is typically ±12 V into 10 kΩ with ±15 V supplies, leaving ~1.5 V headroom from each rail. This limitation is inherent to its Class AB output stage and must be accounted for in circuit design to avoid clipping.
Can TL072CPSRE4 drive capacitive loads?
Yes, TL072CPSRE4 can safely drive up to 300 pF capacitive load without oscillation, per its datasheet specification. For larger loads, external isolation resistance (e.g., 10–100 Ω in series with the output) is required to maintain phase margin and prevent instability.
What is the input offset voltage specification for TL072CPSRE4?
The TL072CPSRE4 has a typical input offset voltage of 6 mV, with a maximum of 10 mV over the full 0°C to 70°C operating temperature range. This value is confirmed in Section 5.8 of the official TI datasheet under "Electrical Characteristics (DC) for TL07xC".
Is TL072CPSRE4 suitable for single-supply operation?
Yes, TL072CPSRE4 supports true single-supply operation from 4.5 V to 40 V. Its input common-mode range extends to VCC+, allowing high-side sensing, and its output swings within ~1.5 V of each rail - making it viable for 5 V, 12 V, or 24 V systems with appropriate biasing.
