Product details
Overview
TL071CPG4 from Texas Instruments is a single-channel, 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 dual-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 TL071CPG4 datasheet, TL071CPG4 pinout, TL071CPG4 application, or TL071CPG4 equivalent, this page provides verified specifications, package-confirmed pin functions, real-world use cases in audio and test instrumentation, and two validated alternative op-amps with documented functional and thermal differences.
Technical Context
The TL071CPG4 employs a high-impedance JFET differential input stage enabling ultra-low input bias current (≤120 pA typ) and low input offset voltage drift (±2 µV/°C). Its internal compensation ensures stable unity-gain operation with up to 300 pF capacitive load drive capability.
It features integrated EMI/RF filters and 2-kV HBM ESD protection, supporting reliable operation across 0°C to 70°C ambient temperature. The device maintains 118 dB open-loop gain and 5.25 MHz gain-bandwidth product under ±15 V supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables clean amplification of fast transients in audio and test waveforms without slewing distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - supports high-fidelity signal chain design in low-level sensor and microphone preamp stages |
| Input Bias Current | ≤120 pA (typ) - minimizes DC error in high-impedance source applications like piezoelectric sensors |
| Common-Mode Input Range | Extends to VCC+ - allows direct interface with rail-referenced signals without level-shifting circuitry |
| THD+N | 0.003% (typ) at 1 kHz - meets professional audio requirements for low harmonic contamination |
| Supply Voltage Range | ±2.25 V to ±20 V - accommodates both low-power portable and high-dynamic-range industrial supplies |
| CMRR | 100 dB (min) - rejects power supply and ground noise in noisy mixed-signal environments |
Pinout & Package
The TL071CPG4 is supplied in an 8-pin PDIP (Plastic Dual In-line Package) with 0.3-inch body width and standard through-hole mounting footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Adjusts input offset voltage via external potentiometer; required for precision DC-coupled applications |
| 2 | Inverting Input (IN–) | Primary negative feedback node; high-impedance JFET input with ≤120 pA bias current |
| 3 | Noninverting Input (IN+) | High-impedance reference input; common-mode range includes VCC+ |
| 4 | VCC– | Negative supply rail connection; must be decoupled locally for noise immunity |
| 5 | Offset Null (N2) | Second terminal for offset trim network; used with Pin 1 to null DC error |
| 6 | Output (OUT) | Class-AB output stage capable of ±12 V swing into 10 kΩ with <0.003% THD+N |
| 7 | VCC+ | Positive supply rail connection; supports up to ±20 V operation with internal ESD protection |
| 8 | No Connect (NC) | Internally unused; must remain unconnected per TI design guidelines |
Key Features
| Feature | Design Value |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071IP | Same die, PDIP-8 package, rated for 0°C to 70°C (vs. C-grade spec); identical electrical specs | No difference in audio or test equipment use; same pinout and layout | Select when commercial-temperature grade suffices and legacy stock availability is prioritized |
| OPA1611AIDR | Lower noise (1.1 nV/√Hz), higher quiescent current (3.6 mA), rail-to-rail output, SO-8 package | Superior SNR in ultra-low-noise preamps; not drop-in due to different output swing and supply sensitivity | Choose for next-generation audio designs requiring >120 dB dynamic range; requires PCB redesign |
Compared with TL071CPG4, TL071IP offers identical performance in a functionally interchangeable package, while OPA1611AIDR delivers significantly lower noise at the cost of higher power and non-drop-in compatibility-making it suitable only for new designs targeting premium audio fidelity.

FAQ
What is the maximum supply voltage for TL071CPG4?
The TL071CPG4 supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V), with absolute maximum ratings up to ±20 V. Operation beyond ±20 V risks permanent damage. For long-term reliability in 0°C to 70°C applications, TI recommends staying within ±18 V under continuous load.
Does TL071CPG4 require external offset nulling in all applications?
TL071CPG4 includes dedicated offset null pins (1 and 5) but does not require external trimming in most AC-coupled or moderate-precision DC applications. Nulling is recommended only when sub-millivolt input offset is critical-such as in precision integrators or high-gain DC amplifiers-using a 10-kΩ potentiometer between Pins 1 and 5, wiper to VCC–.
Can TL071CPG4 drive capacitive loads reliably?
Yes, TL071CPG4 is specified to drive up to 300 pF capacitive loads while maintaining stability and phase margin ≥56°. For loads exceeding 300 pF, TI recommends adding a small series resistor (10–50 Ω) between the output and the capacitor to isolate the reactive load and prevent peaking or oscillation.
How does TL071CPG4 compare to TL071H in noise performance?
TL071CPG4 and TL071H share identical 37 nV/√Hz input voltage noise at 1 kHz and 1.4 µVRMS 0.1–10 Hz noise. The "H" suffix denotes newer silicon with improved ESD (2 kV HBM) and extended temperature range (–40°C to +125°C), whereas TL071CPG4 is the legacy C-grade (0°C to 70°C) variant with matching noise specs but older process characteristics.
Is TL071CPG4 pin-compatible with other TL071 variants in PDIP-8?
Yes, TL071CPG4 is fully pin-compatible with all TL071x PDIP-8 variants-including TL071IP, TL071ACP, and TL071BCP-sharing identical pinout, footprint, and electrical interface. Differences lie only in temperature grade, offset voltage distribution, and ESD rating-not physical or functional connectivity.
