Product details
Overview
TL072CPWRE4 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 stability are critical.
For engineers reviewing the TL072CPWRE4 datasheet, TL072CPWRE4 pinout, TL072CPWRE4 application, or TL072CPWRE4 equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±120 pA typ), wide 5.25 MHz gain-bandwidth product, low 1 mV typical input offset voltage, and TSSOP-8 packaging suitable for space-constrained PCB layouts.
Technical Context
The TL072CPWRE4 implements a dual-channel, high-slew-rate JFET-input op-amp topology with fully differential input stages and Class AB output stages. Its internal architecture supports common-mode input voltage up to VCC+, enabling single-supply operation with proper biasing.
It features integrated EMI/RF filters and 2 kV HBM ESD protection, and operates across –40°C to +85°C (industrial grade). The device exhibits 125 dB open-loop gain and 56° phase margin under standard 10-kΩ/20-pF load conditions, ensuring stable unity-gain buffer and active filter configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2.25 V to ±20 V (4.5 V to 40 V total) - supports dual- and single-supply designs including ±15 V industrial rails |
| Slew Rate | 20 V/μs (typ) - enables faithful reproduction of fast transients in audio and instrumentation signals |
| Input Noise Density | 37 nV/√Hz at 1 kHz - low enough for microphone preamps and sensor front-ends requiring high SNR |
| Input Offset Voltage | ±1 mV (typ), ±4 mV (max) - ensures minimal DC error in precision integrators and transimpedance amplifiers |
| Gain-Bandwidth Product | 5.25 MHz - supports stable closed-loop gains up to ~50 at 100 kHz for anti-aliasing and tone control filters |
| Input Bias Current | ±120 pA (typ) - preserves high-impedance source integrity in photodiode and piezoelectric sensor interfaces |
| Common-Mode Range | Extends to VCC+ - allows direct sensing of signals near positive rail without level-shifting circuitry |
Pinout & Package
The TL072CPWRE4 is housed in an 8-pin TSSOP (PW) package with 0.65 mm pitch, 3.0 mm × 4.4 mm body, and exposed pad for thermal enhancement. It is RoHS-compliant and moisture-sensitive level 1 (MSL-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output - drives loads up to ±26 mA short-circuit current; limited headroom (~210 mV) from positive rail |
| 2 | Inverting Input A | High-impedance FET node - bias current <120 pA enables high-Z feedback networks without drift |
| 3 | Noninverting Input A | High-impedance FET node - common-mode range includes VCC+, supporting rail-to-rail input operation |
| 4 | VCC– | Negative supply rail - must be decoupled locally with 0.1 μF ceramic capacitor |
| 5 | Noninverting Input B | Independent second amplifier input - identical electrical specs to Channel A; no crosstalk coupling above 100 dB |
| 6 | Inverting Input B | Independent second amplifier input - enables dual-stage filtering or differential pair configuration |
| 7 | Output B | Amplifier B output - electrically isolated from Output A; supports independent gain/feedback paths |
| 8 | VCC+ | Positive supply rail - accepts up to +20 V; requires local 0.1 μF ceramic bypass to ground |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Voltage Noise | 37 nV/√Hz at 1 kHz - preserves dynamic range in low-level audio and sensor amplification |
| FET Input Stage | ±120 pA input bias current - eliminates loading errors in high-impedance sources like piezo sensors |
| Rail-Inclusive Common-Mode Range | Operates with inputs up to VCC+ - simplifies single-supply design by removing need for input bias resistors |
| Output Short-Circuit Protection | ±26 mA continuous short-circuit current limit - prevents latch-up and thermal runaway during fault conditions |
| EMI/RF Immunity | Integrated on-chip RF filters - suppresses interference from switching power supplies and wireless transceivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072IP | Dual-channel JFET-input op-amp in PDIP-8; higher thermal resistance (85°C/W RθJA vs 200.3°C/W for PW); no EMI filters | Preferred for through-hole prototyping or legacy board rework; unsuitable for high-density surface-mount production | Select TL072IP only when DIP footprint compatibility is mandatory and EMI immunity is not required |
| OPA2134PA | Lower noise (8 nV/√Hz), lower distortion (0.00008% THD+N), but higher quiescent current (4 mA/ch) and cost; SO-8 only | Better suited for ultra-high-fidelity audio; less ideal for battery-powered or thermally constrained systems | Choose OPA2134PA when SNR >110 dB is required and power budget permits 4× higher IQ |
Compared with TL072IP and OPA2134PA, the TL072CPWRE4 offers the best balance of low noise, low power (940 µA/ch), compact TSSOP-8 packaging, and integrated EMI filtering - making it optimal for cost-sensitive, space-constrained industrial and audio signal chains.

FAQ
What is the maximum supply voltage rating for TL072CPWRE4?
The TL072CPWRE4 supports a total supply voltage (VCC+ to VCC–) of up to 40 V, corresponding to ±20 V dual supply or 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 across temperature and lifetime. Exceeding this risks permanent damage to the JFET input stage.
Does TL072CPWRE4 support single-supply operation?
Yes, TL072CPWRE4 supports true single-supply operation because its common-mode input voltage range extends to VCC+. When powered from, e.g., 0 V and +15 V, inputs can swing from 0 V up to +15 V. However, output swing is limited to ~13.5 V (with 10 kΩ load), so mid-rail biasing (e.g., VCC/2) is required for AC-coupled signals.
How does the noise performance of TL072CPWRE4 compare to bipolar-input op-amps?
TL072CPWRE4 delivers 37 nV/√Hz input voltage noise at 1 kHz - significantly lower than typical bipolar-input op-amps like LM358 (40 nV/√Hz) or NE5532 (5 nV/√Hz only below 100 Hz). Its JFET input also provides ultra-low current noise (80 fA/√Hz), making it superior for high-source-impedance applications where bipolar devices suffer from Johnson-Nyquist and shot noise dominance.
Is TL072CPWRE4 pin-compatible with other TL072 variants?
Yes, TL072CPWRE4 is pin-compatible with all TL072x variants in TSSOP-8 (PW) packaging, including TL072CDR, TL072CPWR, and TL072IPWRE4. Pin functions match Table 4-3 exactly: Pins 1/7 = outputs, 2/6 = inverting inputs, 3/5 = noninverting inputs, 4 = VCC–, 8 = VCC+. No layout changes are needed when substituting within the same PW package.
What is the typical quiescent current per channel for TL072CPWRE4?
The typical quiescent current per channel for TL072CPWRE4 is 940 µA at 25°C and ±15 V supply, with a maximum of 1.125 mA over temperature (–40°C to +85°C). This low power consumption enables use in multi-channel, thermally constrained systems such as portable audio interfaces and multi-channel data acquisition modules.
