Product details
Overview
TL072ACDE4 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 TL072ACDE4 datasheet, TL072ACDE4 pinout, TL072ACDE4 application, or TL072ACDE4 equivalent, key selection criteria include its FET-input architecture enabling ultra-low input bias current (±120 pA typ), low offset drift (±2 µV/°C), and wide supply flexibility-making it suitable for high-fidelity analog front-ends and DC-coupled instrumentation.
Technical Context
The TL072ACDE4 implements a dual-channel, high-slew-rate JFET-input op-amp topology with fully differential input stage and Class AB output stage. Its input stage features matched JFET pairs for low input bias current and low noise, while the internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
It supports single-supply operation down to 4.5 V or split supplies as low as ±2.25 V, with common-mode input range extending to VCC+-enabling direct sensing of signals near the positive rail. The device includes output short-circuit protection and integrated EMI filtering per TI's TL07x family design.
Key Specifications

|---|---|
| Slew Rate | 20 V/μs - enables clean amplification of fast transients in audio and test equipment without slew-induced distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - supports high-resolution signal acquisition in low-level sensor interfaces |
| Input Bias Current | ±120 pA (typ) - minimizes voltage error in high-impedance source applications like piezoelectric sensors |
| Supply Voltage Range | ±2.25 V to ±20 V (or 4.5 V to 40 V) - allows flexible deployment in both battery-powered and industrial line-powered systems |
| Common-Mode Input Range | Includes VCC+ - permits direct interface with signals referenced to the positive supply rail |
| Offset Voltage Drift | ±2 µV/°C - ensures stable DC performance over temperature in precision measurement circuits |
| Quiescent Current | 940 µA per channel - balances low power consumption with high-speed capability for portable instrumentation |
Pinout & Package
TL072ACDE4 is packaged in an 8-pin SOIC (D package) with surface-mount footprint and standard JEDEC MS-012AC dimensions (4.9 mm × 3.9 mm × 1.75 mm). Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier channel - drives external load or next stage with rail-to-rail swing capability |
| 2 | 1IN− | Inverting input of first channel - accepts feedback network or inverted signal path |
| 3 | 1IN+ | Noninverting input of first channel - connects to reference, sensor, or signal source with minimal loading |
| 4 | VCC− | Negative supply rail - must be decoupled locally to suppress ground bounce and noise coupling |
| 5 | 2IN+ | Noninverting input of second channel - electrically isolated from first channel; shares same supply rails |
| 6 | 2IN− | Inverting input of second channel - supports independent gain configuration from Channel 1 |
| 7 | 2OUT | Output of second amplifier channel - provides dual-channel functionality in compact layout |
| 8 | VCC+ | Positive supply rail - requires local 0.1 µF ceramic decoupling capacitor for high-frequency stability |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±120 pA typical - preserves signal integrity in megohm-range sensor interfaces and integrator circuits |
| 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 thermal failure during accidental overload or PCB fault conditions |
| EMI rejection ratio | 53 dB at 1 GHz - maintains signal fidelity in noisy industrial or RF-dense environments |
| Capacitive load drive | 300 pF - eliminates need for isolation resistors when driving ADC inputs or long 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; identical electrical specs but C-grade (0°C to 70°C) and no EMI filter | Lacks integrated EMI/RF filtering; slightly lower ESD rating (1.5 kV HBM vs 2 kV) | Acceptable where board-level EMI mitigation is implemented externally |
| OPA2134PA | Higher precision: 0.5 mV max offset, 8 nV/√Hz noise, 20 V/μs slew; DIP-8 package only | Not pin-compatible; requires PCB redesign; superior audio performance but higher cost | Preferred for premium audio applications where noise and distortion budgets are tighter |
Compared with TL072CDR and OPA2134PA, TL072ACDE4 offers balanced performance with built-in EMI filtering and industry-standard SOIC-8 compatibility-making it ideal for cost-sensitive, noise-resilient industrial signal chains without requiring layout changes.

FAQ
What is the operating temperature range of the TL072ACDE4?
The TL072ACDE4 is rated for operation from 0°C to +70°C (commercial grade). This range is confirmed in Section 5.3 of the TI datasheet under Recommended Operating Conditions for TL07xC variants. It is not rated for extended industrial or automotive temperature ranges-those require TL072I or TL072M suffixes.
Does TL072ACDE4 support single-supply operation?
Yes, TL072ACDE4 supports true single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing input signals to swing up to the positive rail-critical for DC-coupled single-supply designs such as battery-powered test instruments and portable audio gear.
What is the maximum capacitive load TL072ACDE4 can drive stably?
TL072ACDE4 is characterized to drive up to 300 pF capacitively without oscillation or excessive overshoot, as specified in the Electrical Characteristics table (Section 5.7). This eliminates the need for series isolation resistors when interfacing directly with ADC inputs, coaxial cables, or large PCB traces.
How does TL072ACDE4 differ from TL072H variants?
TL072ACDE4 belongs to the TL07xC family (not H), meaning it uses the original die with 37 nV/√Hz noise and 5.25 MHz GBW, whereas TL072H offers improved 20 V/μs slew rate and enhanced EMI filtering. TL072ACDE4 lacks the H-suffix ESD (2 kV HBM) and EMI hardening but retains full pin and functional compatibility.
Is TL072ACDE4 RoHS compliant and lead-free?
Yes, TL072ACDE4 is RoHS compliant and lead-free. Per TI's packaging information (Section 11), the "E4" suffix denotes lead-free, halogen-free, and RoHS-compliant SOIC packaging with NiPdAu lead finish and matte tin lead plating.
