Product details
Overview
TL072ACP from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise audio and precision signal conditioning. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 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 low distortion (0.003% THD+N) and high CMRR (105 dB) are critical.
For engineers reviewing the TL072ACP datasheet, TL072ACP pinout, TL072ACP application, or TL072ACP equivalent, key selection considerations include its FET-input architecture for ultra-low bias current (±1 pA typ), dual-channel SOIC-8 packaging, temperature-stable offset drift (±2 µV/°C), and compatibility with single-supply or split-supply configurations up to 40 V total.
Technical Context
The TL072ACP belongs to the legacy TL072x family and uses a bipolar-compatible JFET input stage with high-impedance differential pair and Class AB output stage. Its internal architecture supports wide common-mode input range (including VCC+) and provides output short-circuit protection without latch-up risk.
It operates across 0°C to 70°C ambient temperature (commercial grade), supports supply voltages from ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended), and maintains stable gain-bandwidth product (5.25 MHz) and phase margin (56°) under capacitive loads up to 300 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables faithful reproduction of fast transients in audio and control loops without slew-induced distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - ensures minimal added noise in low-level sensor amplification and microphone preamp stages |
| Input Bias Current | ±1 pA typical - preserves signal integrity in high-impedance source applications like piezoelectric sensors or photodiode amplifiers |
| Common-Mode Input Range | Includes VCC+ - allows direct interfacing with signals referenced to positive rail, simplifying single-supply design |

| Supply Voltage Range | ±2.25 V to ±20 V (4.5 V to 40 V) - supports flexible power architecture in industrial test equipment and motor drive feedback circuits |
| Offset Voltage Drift | ±2 µV/°C - maintains DC accuracy over temperature in precision instrumentation and calibration systems |
Pinout & Package
The TL072ACP is supplied in an 8-pin PDIP (Plastic Dual In-line Package) with 0.3-inch body width and through-hole mounting. This package offers robust thermal performance (RθJA = 85 °C/W) and mechanical stability for prototyping and legacy PCB designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier A | Provides buffered, low-impedance output signal; capable of sourcing/sinking ±26 mA |
| 2 | Inverting Input of Amplifier A | High-impedance node (ZICM = 6 TΩ || 1 pF); accepts feedback network for inverting configuration |
| 3 | Noninverting Input of Amplifier A | High-impedance node; used for unity-gain buffer or noninverting amplifier topologies |
| 4 | Negative Supply (VCC–) | Reference for dual-supply operation; must be connected even in single-supply use (typically tied to ground) |
| 5 | Noninverting Input of Amplifier B | Independent high-Z input for second channel; electrically isolated from Channel A |
| 6 | Inverting Input of Amplifier B | Independent high-Z input for second channel; supports separate feedback networks per channel |
| 7 | Output of Amplifier B | Second independent output; identical AC/DC specs to Pin 1 |
| 8 | Positive Supply (VCC+) | Primary power rail; common to both amplifiers; supports up to 40 V total supply swing |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±1 pA typical - eliminates significant error voltage across high-value feedback resistors (>1 MΩ) in precision integrators |
| Output Short-Circuit Protection | Internally limited to ±26 mA - prevents device damage during accidental load faults without external current limiting |
| Wide Supply Range | 4.5 V to 40 V total - enables operation from single-cell Li-ion (3.7 V) with boost, or directly from 24 V industrial rails |
| Low Total Harmonic Distortion | 0.003% at 1 kHz - preserves waveform fidelity in analog synthesizers and active crossover networks |
| High Common-Mode Rejection | 105 dB - rejects power supply ripple and EMI coupling in noisy environments such as motor drive PCBs |

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 | SOIC-8 surface-mount package; identical electrical specs but lower RθJA (147.8 °C/W) and no through-hole mounting | Preferred for automated SMT assembly and space-constrained PCBs; not suitable for breadboarding or hand-soldered prototypes | Select TL072CDR when board area and reflow compatibility are prioritized over manual serviceability. |
| RC4558CP | Bipolar input (not JFET); higher input bias current (±300 nA), lower slew rate (1.7 V/μs), but wider temp range (–40°C to +85°C) | Acceptable for cost-sensitive general-purpose amplification where ultra-low noise and bias current are not required | Choose RC4558CP only if noise and input impedance are secondary to cost and availability in consumer-grade audio products. |
Compared with TL072CDR and RC4558CP, the TL072ACP provides superior noise performance and input impedance in a through-hole package ideal for lab validation and legacy industrial designs, while avoiding the thermal limitations of SOIC and the signal integrity compromises of bipolar inputs.

FAQ
What is the maximum supply voltage rating for the TL072ACP?
The TL072ACP supports a total supply voltage range of ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended). Absolute maximum ratings specify 42 V for standard devices, but recommended operating conditions limit continuous operation to 40 V to ensure reliability and parameter stability across temperature.
Does the TL072ACP support single-supply operation?
Yes, the TL072ACP supports true single-supply operation. Its common-mode input voltage range extends to VCC+, allowing inputs to swing up to the positive rail. When used with a single supply, VCC– is typically grounded, and input signals must remain within (VCC–)+1.5 V to VCC+ to maintain specified performance.
What is the input bias current specification for TL072ACP at room temperature?
The TL072ACP exhibits a typical input bias current of ±1 pA at 25°C, with a maximum of ±120 pA. This ultra-low value is enabled by its JFET input stage and makes it suitable for high-impedance sensor interfaces where leakage currents would otherwise dominate error budgets.
How does the TL072ACP compare to the TL072H variant in terms of performance?
The TL072ACP is a commercial-grade (0°C to 70°C) version with typical offset voltage of 3 mV and slew rate of 20 V/μs. The TL072H offers improved specifications: 1 mV typical offset, ±2 µV/°C drift, and guaranteed 20 V/μs slew rate across –40°C to +125°C, making it suitable for extended-temperature industrial applications.
Is the TL072ACP pin-compatible with other dual op-amps in PDIP-8 packages?
Yes, the TL072ACP follows the industry-standard dual op-amp pinout (Pin 1: A-out, Pin 2: A-in–, Pin 3: A-in+, Pin 4: V–, Pin 5: B-in+, Pin 6: B-in–, Pin 7: B-out, Pin 8: V+), ensuring mechanical and functional compatibility with NE5532P, RC4558P, and LM833N in PDIP-8 sockets and PCB footprints.
