Product details
Overview
TL072ACPSRE4 from Texas Instruments is a dual, JFET-input operational amplifier optimized for low-noise audio and precision signal conditioning. It delivers 37 nV/√Hz input voltage noise at 1 kHz, 20 V/μs slew rate, and ±1 mV typical input offset voltage across –40°C to +85°C. It operates from ±2.25 V to ±20 V supplies and supports rail-to-rail output swing into 10 kΩ loads - widely used in pro-audio mixers and battery test equipment.
For engineers reviewing the TL072ACPSRE4 datasheet, TL072ACPSRE4 pinout, TL072ACPSRE4 application, or TL072ACPSRE4 equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±1 pA typ), wide common-mode range extending to VCC+, and guaranteed performance in industrial temperature-grade designs requiring stable DC accuracy and low THD+N (0.003% typ).
Technical Context
The TL072ACPSRE4 implements a high-impedance JFET differential pair input stage followed by a Class AB output stage with short-circuit protection. 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//20 pF load.
It features integrated EMI/RF filters and 2-kV HBM ESD rating, enabling robust operation in electrically noisy environments like motor drive feedback loops and UPS control circuits. The device maintains CMRR ≥ 90 dB and PSRR ≥ 70 dB over full operating temperature and supply ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±20 V (4.5 V to 40 V total) - supports single- or dual-supply operation in battery-powered and line-powered systems |
| Input Offset Voltage | ±1 mV (typ) at 25°C - enables accurate DC-coupled amplification without frequent nulling in sensor interfaces |
| Slew Rate | 20 V/μs (typ) - supports clean reproduction of fast transients in audio and pulse-amplification stages |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - critical for low-noise preamplifiers in microphone and piezoelectric sensor front-ends |
| Common-Mode Input Range | Extends to VCC+ - allows direct sensing of signals referenced to positive rail, e.g., high-side current monitoring |
| THD+N | 0.003% (typ) at 1 kHz - meets fidelity requirements for professional audio mixing and analog test instrumentation |
| Quiescent Current | 1.4 mA per amplifier (max) - balances low power consumption with high-speed performance in portable gear |
Pinout & Package
The TL072ACPSRE4 is housed in an 8-pin SOIC (PS) package with 1.27 mm pitch, 5.3 mm × 6.2 mm body, and gull-wing leads suitable for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier A | Low-impedance buffered output capable of sourcing/sinking ±26 mA; rail headroom ≤215 mV at 10 kΩ load |
| 2 | Inverting Input of Amplifier A | High-impedance FET node (ZICM = 6 TΩ); bias current ±1 pA typ - minimizes loading on high-Z sources |
| 3 | Noninverting Input of Amplifier A | Matches Pin 2 in impedance and leakage; enables precision differential or instrumentation amplifier configurations |
| 4 | Negative Supply (VCC–) | Reference for both amplifiers; must be decoupled locally to suppress ground bounce in dual-channel operation |
| 5 | Noninverting Input of Amplifier B | Independent high-Z input identical to Pin 3 - supports dual-channel signal processing without crosstalk degradation |
| 6 | Inverting Input of Amplifier B | Matches Pin 2; channel separation >100 dB at DC ensures minimal inter-channel coupling in stereo/audio paths |
| 7 | Output of Amplifier B | Electrically identical to Pin 1; allows independent gain staging or summing of two analog signals |
| 8 | Positive Supply (VCC+) | Power rail shared by both amplifiers; requires 0.1 μF ceramic bypass capacitor placed within 3 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±1 pA typical - preserves signal integrity when amplifying from high-impedance sources like photodiodes or pH electrodes |
| Wide supply range | ±2.25 V to ±20 V - eliminates need for external level-shifting in mixed-voltage systems (e.g., 3.3 V logic + ±15 V analog rails) |
| Output short-circuit protection | Self-limiting to ±26 mA - prevents latch-up or thermal runaway during accidental overload or PCB trace shorts |
| EMI/RF rejection | 53 dB at 1 GHz - suppresses cellular/WiFi interference in consumer audio and industrial control enclosures |
| Temperature range | –40°C to +85°C (industrial grade) - validated for use in outdoor UPS units and factory-floor test equipment |

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 |
|---|---|---|---|
| TL072CDR | Same SOIC-8 package; wider offset voltage (±3 mV max) and higher noise (18 nV/√Hz only in PS/NS packages) | Lower-cost option for non-critical audio or general-purpose amplification where 0.003% THD+N is not required | Select TL072CDR when cost sensitivity outweighs need for lowest noise and tightest DC specs |
| OPA2134PA | Higher precision: ±0.5 mV offset, 8 nV/√Hz noise, 20 V/μs slew; requires ±18 V max supply | Targeted at premium audio and medical instrumentation where ultra-low distortion and noise are mandatory | Choose OPA2134PA when system-level SNR or THD+N budget demands sub-0.001% performance |
Compared with TL072CDR, TL072ACPSRE4 offers tighter DC accuracy and lower noise for demanding signal chains; versus OPA2134PA, it trades some precision for broader supply flexibility and lower cost - making TL072ACPSRE4 optimal for industrial audio and test equipment balancing performance and robustness.

FAQ
What is the maximum capacitive load the TL072ACPSRE4 can drive stably?
The TL072ACPSRE4 is characterized to drive up to 300 pF capacitively without oscillation under unity-gain conditions, thanks to internal compensation and 56° phase margin. For loads exceeding 300 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to maintain stability in high-impedance sensor buffering applications using TL072ACPSRE4.
Does the TL072ACPSRE4 support single-supply operation?
Yes, the TL072ACPSRE4 supports true single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing inputs to be referenced directly to the positive rail - ideal for high-side sensing in battery monitors and DC-DC converter feedback loops using TL072ACPSRE4.
How does the TL072ACPSRE4 compare to the TL072H variant in noise performance?
The TL072ACPSRE4 (C-grade) specifies 37 nV/√Hz input voltage noise at 1 kHz, matching the TL072H. Both share identical noise density; however, TL072H guarantees operation to +125°C and has tighter offset drift (±2 µV/°C vs ±18 µV/°C for C-grade), while TL072ACPSRE4 is rated for –40°C to +85°C - confirming TL072ACPSRE4's suitability for industrial audio and test gear.
Is the TL072ACPSRE4 pin-compatible with other TL072 variants in SOIC-8?
Yes, TL072ACPSRE4 uses the standard 8-pin SOIC (PS) footprint and shares identical pinout with all TL072x variants in D, P, PS, and PW packages - including TL072CDR, TL072IDR, and TL072HPSR. This allows drop-in replacement in existing layouts without PCB revision when upgrading to the A-grade performance tier.
What is the quiescent current of the TL072ACPSRE4 per amplifier?
The TL072ACPSRE4 draws 1.4 mA per amplifier maximum (2.8 mA total) at ±15 V supply and 25°C, with typical consumption of 1.125 mA per channel. This value remains stable across –40°C to +85°C, enabling predictable power budgeting in thermally constrained battery test fixtures and compact audio modules using TL072ACPSRE4.
