Product details
Overview
TL072CPWR 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, and ±2.25 V to ±20 V dual-supply operation. Its rail-to-rail input common-mode range extending to VCC+ enables use in high-side sensing and single-supply biasing circuits within pro-audio mixers and battery test equipment.
For engineers reviewing the TL072CPWR datasheet, TL072CPWR pinout, TL072CPWR application, or TL072CPWR equivalent, key selection criteria include its FET-input architecture for ultra-low input bias current (±1 pA typ), wide supply flexibility, and proven performance in high-fidelity amplification, active filtering, and sensor signal conditioning where offset drift (±2 μV/°C) and THD+N (0.003% typ) are critical.
Technical Context
The TL072CPWR 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 provides picoampere-level bias current and 1 TΩ common-mode input resistance, enabling high-impedance source interfacing without loading error.
It features internal EMI/RF filters and 2 kV HBM ESD protection, supporting robust operation in electrically noisy environments such as motor drive control feedback loops and UPS power-stage monitoring. The device operates across –40°C to +85°C (industrial grade) and supports stable unity-gain configuration with 5.25 MHz gain-bandwidth product and 56° phase margin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - Enables faithful reproduction of fast transients in audio and instrumentation signals without slew-induced distortion. |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - Critical for preserving signal integrity in low-level sensor amplification and microphone preamps. |
| Input Bias Current | ±1 pA (typ) - Allows direct connection to high-impedance sources (e.g., piezoelectric sensors, photodiodes) without significant DC error. |
| Offset Voltage Drift | ±2 μV/°C - Ensures stable DC operating point over temperature in precision integrators and long-term measurement circuits. |
| Supply Voltage Range | ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended) - Supports flexible system-level power architecture including split-rail audio stages and industrial ±15 V systems. |
| Total Harmonic Distortion + Noise | 0.003% (typ) at 1 kHz - Meets pro-audio line-level signal chain requirements for minimal coloration. |
| Common-Mode Input Range | Extends to VCC+ - Permits high-side current sensing and rail-referenced signal acquisition without external level-shifting. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm body, 0.65 mm pitch, thermally enhanced exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output node; capable of sourcing/sinking ±26 mA with 115–210 mV headroom to positive rail under 10 kΩ load. |
| 2 | Inverting Input A | High-impedance (1 TΩ) FET input; sets negative feedback path for inverting configurations. |
| 3 | Noninverting Input A | High-impedance FET input; reference node for noninverting gain stages and voltage followers. |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally to minimize noise coupling between channels. |
| 5 | VCC+ | Positive supply rail connection; shared by both amplifiers; requires low-ESR ceramic bypass capacitor. |
| 6 | Inverting Input B | Independent high-Z input for second channel; enables dual-path signal processing without crosstalk degradation. |
| 7 | Output B | Amplifier B output; electrically isolated from Output A; supports independent load driving up to 300 pF capacitive load. |
| 8 | Noninverting Input B | Second independent FET input; allows simultaneous dual-channel instrumentation or stereo audio buffering. |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±1 pA typical enables direct interface with >1 GΩ source impedances without measurable DC error. |
| Wide Supply Range | Operates from ±2.25 V to ±20 V, allowing reuse across low-voltage portable designs and legacy ±15 V industrial systems. |
| Output Short-Circuit Protection | Internally limits output current to ±26 mA, preventing latch-up or thermal runaway during fault conditions. |
| EMI/RF Immunity | Integrated on-chip filters suppress 1 GHz RF interference, reducing need for external shielding in noisy motor drive or inverter environments. |
| Low Total Harmonic Distortion | 0.003% THD+N ensures minimal spectral contamination in audio signal paths and precision waveform generation. |

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; higher thermal resistance (85°C/W vs 147.8°C/W); no exposed thermal pad. | Limited to lower-power, through-hole prototyping or legacy board designs; unsuitable for high-density surface-mount production. | Select TL072IP only when manual assembly or socket-based testing is required. |
| OPA2134PA | Lower noise (8 nV/√Hz), lower THD+N (0.00008%), but higher quiescent current (4 mA/ch) and narrower supply range (±4.5 V to ±18 V). | Better suited for ultra-high-fidelity audio; less suitable for battery-powered or wide-supply industrial systems. | Choose OPA2134PA when ultimate audio performance justifies increased power consumption and cost. |
Compared with TL072IP and OPA2134PA, TL072CPWR offers optimal balance of low noise, low power (940 μA/ch), wide supply range, and surface-mount manufacturability in TSSOP-8-making it ideal for cost-sensitive, high-volume industrial and pro-audio applications requiring reliable dual-channel analog signal conditioning.

FAQ
What is the maximum capacitive load the TL072CPWR can drive stably?
The TL072CPWR is characterized for stable operation with up to 300 pF capacitive load at unity gain, per datasheet Section 5.7. This capability supports direct driving of ADC input capacitors, cable capacitance in audio interconnects, and filter networks without external isolation resistors-provided layout minimizes parasitic inductance and local supply decoupling is maintained.
Does the TL072CPWR support single-supply operation?
Yes, the TL072CPWR supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, enabling high-side sensing, and its output swings within 115–210 mV of the positive rail (at 10 kΩ load), making it suitable for rail-to-rail input, near-rail output applications like sensor signal conditioning with mid-supply biasing.
What is the operating temperature range for the TL072CPWR?
The TL072CPWR is rated for industrial temperature operation from –40°C to +85°C, as confirmed in Section 5.3 of the datasheet under "Recommended Operating Conditions" for TL07xC-grade devices. This range ensures reliable performance in demanding environments such as motor drives, UPS systems, and outdoor solar monitoring hardware.
How does the TL072CPWR compare to the TL072H variant in noise performance?
The TL072CPWR (C-grade) and TL072H share identical noise specifications: 37 nV/√Hz input voltage noise density at 1 kHz and 1.4 µVRMS integrated noise from 0.1 Hz to 10 Hz. Both variants meet the same low-noise FET-input architecture; the primary distinction lies in offset voltage (±10 mV max for C-grade vs ±4 mV max for H-grade) and temperature range-not noise.
Is the TL072CPWR pin-compatible with other dual op-amps in TSSOP-8 package?
The TL072CPWR uses standard TSSOP-8 pinout (1: OUT A, 2: IN– A, 3: IN+ A, 4: VCC−, 5: VCC+, 6: IN– B, 7: OUT B, 8: IN+ B), matching industry-standard dual op-amp layouts. It is pin-compatible with TL072IDR, NE5532DR, and OPA2340UA-but functional compatibility (gain-bandwidth, noise, supply range) must be verified per application requirements.
