Product details
Overview
TL072ACDRG4 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 range, and operates across 0°C to 70°C. It is widely used in pro audio mixers and battery test equipment where high CMRR and rail-to-rail common-mode input (including VCC+) are critical.
For engineers reviewing the TL072ACDRG4 datasheet, TL072ACDRG4 pinout, TL072ACDRG4 application, or TL072ACDRG4 equivalent, this page provides verified electrical specifications, SOIC-8 package layout, dual-channel FET-input architecture details, and validated alternatives for audio front-ends, sensor signal chains, and industrial instrumentation designs.
Technical Context
The TL072ACDRG4 implements a dual-channel, high-slew-rate JFET-input op-amp topology with fully differential input stages and Class AB output stages. Its input stage uses matched JFET pairs to achieve ultra-low input bias current (≤120 pA typ) and low offset drift (2 μV/°C).
It supports wide supply operation (±2.25 V to ±20 V), features integrated EMI/RF filters, and maintains stable unity-gain performance with capacitive loads up to 300 pF - enabling direct interface with ADC drivers and active filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables clean amplification of fast transients in audio and test equipment signals without slew-induced distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - ensures minimal added noise in low-level microphone or sensor preamplifier stages |
| Input Bias Current | 120 pA (typ) - preserves signal integrity in high-impedance source applications like piezoelectric sensors |
| Common-Mode Input Range | Includes VCC+ - allows direct sensing of 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 both low-voltage portable systems and high-voltage industrial rails |
| Offset Voltage Drift | 2 μV/°C - maintains DC accuracy over temperature in precision instrumentation and calibration circuits |
| Total Harmonic Distortion + Noise | 0.00012% (typ) at 1 kHz - meets pro-audio THD+N requirements for line-level signal paths |
Pinout & Package
TL072ACDRG4 is housed in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier channel - drives downstream stages with ±12 V swing into 10 kΩ load |
| 2 | 1IN− | Inverting input of first channel - accepts feedback networks for precise gain control |
| 3 | 1IN+ | Noninverting input of first channel - connects to high-impedance sources with minimal loading |
| 4 | VCC− | Negative power supply terminal - must be decoupled locally with 0.1 μF ceramic capacitor |
| 5 | 2IN+ | Noninverting input of second channel - electrically isolated from Channel 1 for dual-path signal processing |
| 6 | 2IN− | Inverting input of second channel - supports independent feedback configuration per channel |
| 7 | 2OUT | Output of second amplifier channel - provides matched AC performance to Channel 1 |
| 8 | VCC+ | Positive power supply terminal - supplies both channels; requires local 0.1 μF bypass |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | 120 pA typical - preserves signal fidelity in photodiode and pH probe interfaces |
| High CMRR | 105 dB (typ) - rejects power supply ripple and shared-noise coupling in multi-stage analog chains |
| Output short-circuit protection | ±26 mA continuous - prevents latch-up or damage during transient overload conditions |
| EMI/RF rejection | 53 dB at 1 GHz - suppresses cellular and switching regulator interference in noisy industrial environments |
| Capacitive load drive | 300 pF - eliminates need for isolation resistors when driving ADC inputs or coaxial cables |

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 (3–10 mV vs. 1–4 mV typ) and higher noise (18 nV/√Hz in PS/NS packages) | Lower-cost option for non-critical audio or general-purpose gain blocks where 0.003% THD+N is acceptable | Select TL072CDR only if budget constraints outweigh need for lowest noise and tightest offset specs |
| OPA2134PA | Higher precision: 0.5 mV max offset, 8 nV/√Hz noise, 20 V/μs slew, but requires ±4.5 V to ±18 V supply | Preferred for studio-grade audio preamps and medical instrumentation requiring sub-mV DC accuracy | Choose OPA2134PA when system-level noise budget or DC stability demands exceed TL072ACDRG4 capability |
Compared with TL072CDR, TL072ACDRG4 offers tighter offset and lower noise for demanding audio paths; compared with OPA2134PA, it trades some precision for broader supply range and cost efficiency in industrial signal conditioning.

FAQ
What is the maximum supply voltage for TL072ACDRG4?
The TL072ACDRG4 supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V). Absolute maximum ratings specify 42 V for most packages, but recommended operating conditions limit VS to 40 V to ensure long-term reliability and specified performance across temperature.
Does TL072ACDRG4 include ESD protection?
Yes, TL072ACDRG4 features integrated ESD protection rated at ±2000 V HBM and ±1000 V CDM per JEDEC standards. This enables robust handling during PCB assembly and operation in environments with moderate electrostatic discharge risk, such as benchtop test equipment and industrial control panels.
Can TL072ACDRG4 drive capacitive loads directly?
Yes, TL072ACDRG4 is characterized to drive up to 300 pF capacitive loads without oscillation or excessive overshoot. This capability simplifies interface design with ADC inputs, coaxial cables, and filtering networks - eliminating the need for series isolation resistors in many applications.
What is the input common-mode voltage range of TL072ACDRG4?
The TL072ACDRG4 features a rail-to-rail common-mode input range that extends to VCC+, meaning it accepts input signals from (VCC−) + 1.5 V up to VCC+. This allows direct connection to sensors or dividers referenced to the positive supply, reducing external level-shifting components in single-supply configurations.
How does TL072ACDRG4 compare to TL072H in noise performance?
TL072ACDRG4 and TL072H share identical noise specifications: 37 nV/√Hz at 1 kHz and 1.4 µVRMS (0.1 Hz–10 Hz). Both belong to the same die generation (H-suffix family), and TL072ACDRG4 is the commercial-grade variant (0°C to 70°C) of the broader TL072H product line, maintaining full electrical compatibility in noise-critical applications.
