Product details
Overview
TL072CDRG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise, high-slew-rate analog signal conditioning in audio and precision instrumentation. 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 deployed in pro audio mixers and battery test equipment where FET-input stability and low distortion are critical.
For engineers reviewing the TL072CDRG4 datasheet, TL072CDRG4 pinout, TL072CDRG4 application, or TL072CDRG4 equivalent, this page provides verified electrical specifications, SOIC-8 package terminal mapping, real-world use cases in audio and power electronics, and two validated alternative op-amps with documented functional and thermal differences.
Technical Context
The TL072CDRG4 implements a dual-channel, high-impedance JFET differential input stage followed by a Class AB output stage, enabling wide common-mode input range (including VCC+) and low input bias current (±1 pA typ). Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
It operates across 0°C to 70°C ambient temperature with ±15 V nominal supply, delivering 115–125 dB open-loop gain, 5.25 MHz gain-bandwidth product, and 0.00012% THD+N at 1 kHz - characteristics confirmed for the 'C' grade variant per TI SLOS080W Rev. July 2025.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| 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 - supports high-fidelity signal chains in microphone preamps and sensor interfaces |
| Input Bias Current | ±65 pA (max) - preserves accuracy in high-impedance source applications like photodiode amplifiers |
| Supply Voltage Range | ±2.25 V to ±20 V - accommodates both low-voltage portable systems and industrial ±15 V rails |
| Common-Mode Input Range | Extends to VCC+ - allows direct sensing of signals referenced to positive supply (e.g., single-supply biasing) |
| THD+N | 0.00012% at 1 kHz - meets pro-audio line-level distortion requirements (< –110 dB) |
| Quiescent Current | 1.4–2.5 mA per channel - balances low-power operation with performance in battery-powered test gear |
Pinout & Package
TL072CDRG4 is supplied 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; leads are gull-wing, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives external load or feedback network; capable of ±12 V swing into 10 kΩ |
| 2 | 1IN− | Inverting input of first amplifier - accepts feedback or signal inversion; high-impedance JFET node (ZICM = 6 TΩ) |
| 3 | 1IN+ | Noninverting input of first amplifier - reference point for follower or noninverting gain stages |
| 4 | VCC− | Negative supply rail - must be decoupled locally; supports −2.25 V minimum for full spec compliance |
| 5 | 2IN+ | Noninverting input of second amplifier - electrically isolated from Channel 1; shares same VCC rails |
| 6 | 2IN− | Inverting input of second amplifier - independent high-Z node; no crosstalk with Channel 1 inputs |
| 7 | 2OUT | Output of second amplifier - fully buffered; short-circuit protected to ±26 mA |
| 8 | VCC+ | Positive supply rail - supplies both amplifiers; common-mode range includes this pin |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±65 pA max (TA = 25°C) - minimizes voltage error in high-source-impedance circuits (e.g., piezoelectric sensors) |
| High CMRR | 70–100 dB - rejects power-supply ripple and ground noise in single-ended measurement front-ends |
| Output short-circuit protection | ±26 mA continuous - prevents latch-up or destruction during overload or wiring faults |
| Wide supply range | ±2.25 V to ±20 V - eliminates need for level-shifting in mixed-voltage systems |
| Low total harmonic distortion | 0.00012% at 1 kHz - preserves spectral purity in analog audio paths and precision DAC buffers |

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 |
|---|---|---|---|
| TL072IP | PDIP-8 package; wider operating temperature (–40°C to +85°C); identical electrical specs to TL072C grade | Preferred for through-hole prototyping or legacy board rework; lacks SOIC's thermal performance and density | Select when manual soldering, breadboarding, or compatibility with older DIP footprints is required |
| OPA2134PA | Lower noise (8 nV/√Hz), lower THD+N (0.00008%), higher quiescent current (4 mA/ch), SOIC-8 | Targeted at ultra-high-fidelity audio; not drop-in due to different bias current (±200 pA) and supply sensitivity | Choose for premium audio paths where noise and distortion dominate over power budget |
Compared with TL072CDRG4, TL072IP offers identical performance in a through-hole format ideal for development, while OPA2134PA trades higher power for superior audio-grade linearity - making TL072CDRG4 the optimal balance of cost, noise, and supply flexibility for industrial signal conditioning.

FAQ
What is the maximum supply voltage for TL072CDRG4?
The TL072CDRG4 supports a total supply voltage (VCC+ minus VCC−) of up to ±20 V (40 V total), with absolute maximum ratings specifying 42 V for non-NS/PS packages. Operation at ±15 V is typical in industrial and audio designs, and the device maintains full specification compliance across ±2.25 V to ±20 V.
Does TL072CDRG4 have rail-to-rail input capability?
Yes, the TL072CDRG4 features a common-mode input voltage range that extends to VCC+, satisfying rail-to-rail input functionality on the positive side. Its common-mode range is specified as (VCC−) + 1.5 V to VCC+, enabling direct interfacing with signals referenced to the positive rail - a key advantage over many bipolar-input op-amps.
What is the input bias current of TL072CDRG4 at 25°C?
The TL072CDRG4 exhibits a maximum input bias current of ±65 pA at 25°C, with typical values near ±1 pA. This ultra-low bias current stems from its JFET input stage and makes the device suitable for high-impedance sensor interfaces, such as photodiode amplifiers and piezoelectric transducers, where leakage-induced offset must be minimized.
Can TL072CDRG4 drive capacitive loads?
Yes, the TL072CDRG4 is characterized to safely drive capacitive loads up to 300 pF while maintaining stability, as confirmed in Section 5.7 of the TI SLOS080W datasheet. For loads exceeding 300 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to prevent peaking or oscillation.
Is TL072CDRG4 suitable for single-supply operation?
Yes, TL072CDRG4 supports single-supply operation with VCC− grounded and VCC+ between 4.5 V and 40 V. Its common-mode input range includes the positive rail, allowing input signals up to VCC+, though output swing remains limited to ~115 mV from each rail under 10 kΩ load - requiring careful headroom planning in true rail-to-rail output applications.
