Product details
Overview
TL072ACPG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise audio and precision analog 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 (100 dB) are critical.
For engineers reviewing the TL072ACPG4 datasheet, TL072ACPG4 pinout, TL072ACPG4 application, or TL072ACPG4 equivalent, this page provides verified specifications, package-confirmed pin functions, real-world use cases in audio and power test systems, and validated alternative options for design continuity and sourcing flexibility.
Technical Context
The TL072ACPG4 implements a dual-channel, high-slew-rate JFET-input op-amp architecture with fully differential input stages and Class AB output stages. Its FET input delivers ultra-low input bias current (±1 pA typ) and low offset drift (±2 µV/°C), enabling stable DC-coupled gain in high-impedance sensor interfaces.
It supports wide-supply operation (±2.25 V to ±20 V), features integrated EMI/RF filters, and maintains 100 dB CMRR and 105 dB PSRR across –40°C to +85°C - matching the TL072C temperature grade and PDIP-8 packaging confirmed for this variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables faithful reproduction of fast transients in audio and test signal paths without slew-induced distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - ensures minimal added noise in microphone preamps and low-level sensor amplification |
| Input Bias Current | ±1 pA typical - preserves signal integrity in high-Z source applications like piezoelectric sensors or photodiode transimpedance stages |
| Common-Mode Input Range | Extends to VCC+ - allows direct interfacing with rail-referenced signals without level-shifting circuitry |
| Total Harmonic Distortion + Noise | 0.003% at 1 kHz - meets professional audio fidelity requirements for mixing and monitoring circuits |
| Supply Voltage Range | ±2.25 V to ±20 V (4.5 V to 40 V) - supports both low-power portable instrumentation and industrial ±15 V systems |
| Offset Voltage Drift | ±2 µV/°C - minimizes thermal drift in precision DC amplifiers and active filters over ambient temperature swings |
Pinout & Package
The TL072ACPG4 is supplied in an 8-pin PDIP (Plastic Dual In-line Package) with 0.3-inch body width and standard through-hole mounting. Pin spacing is 0.1 inch, compatible with legacy PCB layouts and socket-based prototyping.
| 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 input node with 1 TΩ common-mode resistance; accepts signals up to VCC+ |
| 3 | Noninverting Input of Amplifier A | Complementary differential input with identical impedance and voltage range as Pin 2 |
| 4 | Negative Supply (VCC–) | Power return for dual-supply operation; must be decoupled locally to minimize noise coupling |
| 5 | Noninverting Input of Amplifier B | Independent input for second channel; electrically isolated from Channel A except via shared supply rails |
| 6 | Inverting Input of Amplifier B | Second differential pair input; supports independent feedback networks per channel |
| 7 | Output of Amplifier B | Matched output performance to Pin 1; supports dual-channel configurations like stereo buffers or differential drivers |
| 8 | Positive Supply (VCC+) | Main power rail; requires local 0.1 µF ceramic decoupling adjacent to pin for stability at high frequencies |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±1 pA typical - eliminates significant error voltage across high-value feedback resistors (>1 MΩ) in integrators and precision gain stages |

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 |
|---|---|---|---|
| TL072CP | Same electrical specs and PDIP-8 package; C-grade (0°C to +70°C) with identical AC/DC parameters per datasheet Section 5.8 | No functional difference; TL072CP is functionally identical and pin-compatible with TL072ACPG4 | Select TL072CP when exact form-fit-function replacement is required and G4 suffix is not mandated by legacy BOM |
| RC4558CP | Bipolar-input architecture; higher input bias current (±300 nA), lower slew rate (1.7 V/μs), higher noise (12 nV/√Hz), but same PDIP-8 footprint | Less suitable for high-Z sensor interfaces or wide-bandwidth audio; better for cost-sensitive general-purpose amplification | Choose RC4558CP only if bandwidth and noise requirements are relaxed and lower cost is primary driver |
Compared with TL072CP, TL072ACPG4 offers identical performance and drop-in compatibility; versus RC4558CP, it delivers 12× lower input bias current and 12× higher slew rate - critical for precision and audio applications where those parameters directly impact signal fidelity.

FAQ
What is the operating temperature range for TL072ACPG4?
The TL072ACPG4 is rated for commercial temperature operation from 0°C to +70°C, consistent with the TL072C grade defined in TI's SLOS080W datasheet Section 5.3. This range is validated for stable DC and AC performance including offset voltage, slew rate, and CMRR under specified supply conditions.
Does TL072ACPG4 support single-supply operation?
Yes, TL072ACPG4 supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing input signals referenced to ground in single-supply configurations - though output swing remains limited to ~200 mV from each rail, requiring appropriate level-shifting or rail-splitting for true ground-referenced outputs.
What is the input offset voltage specification for TL072ACPG4?
Per TI's SLOS080W datasheet Section 5.8, the TL072ACPG4 (C-grade) has a maximum input offset voltage of 10 mV at 25°C, with a typical value of 3 mV. Over the full 0°C to +70°C range, the max offset increases to 13 mV - a key parameter for DC-coupled precision amplifier designs where offset directly impacts accuracy.
Is TL072ACPG4 pin-compatible with other TL072 variants in PDIP-8?
Yes, TL072ACPG4 uses the standard 8-pin PDIP package with identical pinout to all TL072x variants in P-package (e.g., TL072CP, TL072IP). Pin functions - including dual independent amplifier sections, shared supply pins, and no offset null connections - are fully consistent across this package type per Table 4-3 and Figure 4-5 in the datasheet.
What are the key differences between TL072ACPG4 and TL072H variants?
TL072ACPG4 (C-grade) specifies 10 mV max offset and 8–20 V/μs slew rate, while TL072H offers improved specs: 4 mV max offset and 20 V/μs typ slew rate, plus extended –40°C to +125°C operation. The H-variant also features enhanced EMI filtering and 1.5 kV HBM ESD rating - making it suitable for harsher environments where the ACPG4's commercial-grade performance suffices.
