Product details
Overview
TL072ACD from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise, high-slew-rate precision signal conditioning in audio and industrial analog circuits. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V dual-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 FET-input stability and low distortion (0.003% THD+N) are critical.
For engineers reviewing the TL072ACD datasheet, TL072ACD pinout, TL072ACD application, or TL072ACD equivalent, this page provides verified specifications, SOIC-8 package terminal mapping, real-world use cases in audio and power electronics, and two validated alternative parts with documented functional and thermal differences.
Technical Context
The TL072ACD uses a JFET-input differential pair architecture enabling ultra-low input bias current (≤120 pA typ) and high input impedance (>1 TΩ), making it suitable for high-source-impedance sensor interfaces and integrator circuits. Its internal compensation ensures unity-gain stability with ≥5.25 MHz gain-bandwidth product and 56° phase margin under standard 10 kΩ/20 pF load conditions.
It operates across 0°C to 70°C ambient temperature with ±15 V nominal supply, supports common-mode input voltages up to VCC+, and features output short-circuit protection. The device exhibits low offset drift (±2 μV/°C) and integrated EMI filtering-key for noise-sensitive instrumentation in electrically harsh environments.
Key Specifications

|---|---|
| Slew Rate | 20 V/μs - enables clean amplification of fast transients in audio and control loops without slew-induced distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - preserves signal integrity in low-level microphone preamp and sensor front-end stages |
| Input Bias Current | ≤120 pA (typ) - minimizes voltage error in high-impedance photodiode or piezoelectric sensor interfaces |
| Supply Voltage Range | ±2.25 V to ±20 V - supports flexible bipolar operation in legacy industrial and audio systems |
| Common-Mode Input Range | Extends to VCC+ - allows direct sensing of signals referenced to positive rail, e.g., current-sense amplifiers |
| Total Harmonic Distortion + Noise | 0.003% (typ) at 1 kHz - meets fidelity requirements for professional audio mixing and line-level processing |
| Quiescent Current per Channel | 1.4–2.5 mA - balances performance and power efficiency in dual-channel analog signal chains |
Pinout & Package
TL072ACD is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package, surface-mount compatible with standard reflow profiles and IPC-7351B footprint D_300X190X100_P1270X2000.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier A | Low-impedance buffered output capable of driving ≥10 kΩ loads with <210 mV headroom to positive rail |
| 2 | Inverting Input of Amplifier A | Differential node accepting feedback networks; high-impedance JFET input minimizes loading on source |
| 3 | Noninverting Input of Amplifier A | Reference node for single-ended or differential configurations; accepts common-mode voltages up to VCC+ |
| 4 | Negative Supply (VCC–) | Ground reference for dual supply; must be decoupled locally to suppress PSRR degradation above 100 Hz |
| 5 | Noninverting Input of Amplifier B | Independent input for second channel; identical electrical characteristics to Pin 3 |
| 6 | Inverting Input of Amplifier B | Second channel feedback node; isolated from Channel A to maintain >100 dB channel separation |
| 7 | Output of Amplifier B | Matched output stage to Pin 1; supports independent loading and AC coupling without crosstalk |
| 8 | Positive Supply (VCC+) | Main power rail; requires 0.1 μF ceramic + 10 μF tantalum decoupling per amplifier pair for stable high-frequency operation |

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 and pinout; wider operating temperature range (0°C to 70°C vs TL072ACD's 0°C to 70°C), identical AC/DC specs except slightly higher max input offset voltage (10 mV vs 6 mV) | Valid for cost-sensitive industrial controls where tighter initial offset is noncritical | Select TL072CDR when BOM consolidation across multiple TL072 variants is prioritized and offset drift tolerance is ≥±18 μV/°C |
| OPA2134PA | Higher precision: 0.5 mV max offset, 8 nV/√Hz noise, 20 V/μs slew, but higher quiescent current (4 mA/ch) and SO-8 package with different thermal resistance (RθJA = 125°C/W) | Preferred in studio-grade audio where ultra-low noise and distortion outweigh power budget constraints | Choose OPA2134PA only when THD+N < 0.0005% and noise < 10 nV/√Hz are mandatory, and PCB layout accommodates higher thermal dissipation |
Compared with TL072CDR, TL072ACD offers tighter initial offset (6 mV max) and lower drift (±2 μV/°C), while OPA2134PA delivers superior noise and offset performance at higher power and cost-making TL072ACD the optimal balance for mid-tier audio and industrial signal chains requiring proven reliability and JEDEC-standard SOIC compatibility.

FAQ
What is the maximum supply voltage rating for TL072ACD?
The TL072ACD supports a total supply voltage (VCC+ – VCC–) of up to 40 V, corresponding to ±20 V dual supply or 4.5 V to 40 V single supply. Absolute maximum ratings specify –0.3 V to 36 V for NS/PS packages; operation beyond 40 V risks permanent damage and violates JEDEC stress limits defined in Section 5.1 of the official datasheet.
Does TL072ACD have rail-to-rail output capability?
No, TL072ACD does not feature rail-to-rail output. At ±15 V supply and 10 kΩ load, its output swings within 115–210 mV of the positive rail and 105–215 mV of the negative rail. This limited headroom necessitates design margining in applications requiring full-scale output swing, such as DAC buffer stages.
Is TL072ACD suitable for single-supply operation?
Yes, TL072ACD supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, enabling direct sensing of signals referenced to the positive rail. However, output swing remains asymmetric-designers must bias inputs near mid-supply and verify headroom margins for intended load conditions.
What is the input offset voltage specification for TL072ACD?
The TL072ACD has a maximum input offset voltage of 6 mV at 25°C, with typical value of 3 mV. Over full temperature range (0°C to 70°C), offset drift is ±2 μV/°C. These values are confirmed in Section 5.8 of the TI datasheet SLOS080W and distinguish TL072ACD from standard TL072C (10 mV max) and TL072I (6 mV max, –40°C to +85°C).
How does TL072ACD compare to TL072H in noise performance?
TL072ACD and TL072H share identical input voltage noise density: 37 nV/√Hz at 1 kHz. Both belong to the same die family and exhibit matching low-frequency noise (1.4 µVRMS, 0.1–10 Hz). The "H" suffix denotes newer process fabrication with enhanced ESD (2 kV HBM) and extended temperature range (–40°C to +125°C), whereas TL072ACD targets commercial-grade 0°C to 70°C operation with optimized cost/performance trade-off.
