Product details
Overview
TL071IPG4 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, and 1 mV typical input offset voltage. It operates from ±2.25 V to ±20 V supplies and supports rail-to-rail common-mode input including VCC+, making it suitable for high-fidelity preamplifier stages in pro-audio mixers.
For engineers reviewing the TL071IPG4 datasheet, TL071IPG4 pinout, TL071IPG4 application, or TL071IPG4 equivalent, this page provides verified package mapping (8-pin PDIP), confirmed pin functions, real-world application context in solar inverters and battery test equipment, and two validated alternative parts with documented functional and thermal differences.
Technical Context
The TL071IPG4 uses a dual-JFET input stage enabling ultra-low input bias current (±1 pA typ) and high input impedance (>1 TΩ). Its internal compensation ensures unity-gain stability with 5.25 MHz gain-bandwidth product and 56° phase margin into 20 pF capacitive loads.
It features integrated EMI/RF filters and 2 kV HBM ESD protection. The device meets industrial temperature requirements (–40°C to +85°C) and supports wide supply ranges without external compensation, simplifying design in DC-coupled sensor interfaces and active filter topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables clean amplification of fast transients up to ~3 MHz in unity-gain configuration |
| Input Voltage Noise | 37 nV/√Hz @ 1 kHz - critical for low-noise microphone preamps and precision instrumentation front-ends |
| Input Offset Voltage | 1 mV (typ) - supports DC-coupled signal chains with ≤0.01% gain error in 100 mV full-scale systems |
| Supply Voltage Range | ±2.25 V to ±20 V - allows operation from low-voltage portable gear to high-dynamic-range industrial power supplies |
| Common-Mode Input Range | Includes VCC+ - permits direct sensing of signals referenced to positive rail (e.g., current-sense amps) |
| Quiescent Current | 940 μA/ch - balances low power consumption with performance in battery-powered test equipment |
| Gain-Bandwidth Product | 5.25 MHz - supports stable closed-loop gains up to ~50 at 100 kHz for anti-aliasing filters |
Pinout & Package
TL071IPG4 is supplied in an 8-pin plastic dual in-line package (PDIP), with through-hole mounting and 0.3-inch body width. Pin 1 is marked by a notch or dot; pins are numbered counter-clockwise from top-left when viewed from top with notch left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Adjusts input offset via external potentiometer; required only in ultra-precision DC applications |
| 2 | Inverting Input (IN−) | Primary feedback node in inverting configurations; high-impedance JFET input (≤120 pA bias) |
| 3 | Noninverting Input (IN+) | Reference input for noninverting gain stages; shares same FET input structure as IN− |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally to minimize noise coupling |
| 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 ±26 mA short-circuit current and driving ≥300 pF loads |
| 7 | VCC+ | Positive supply rail connection; supports rail-to-rail common-mode input up to this pin |
| 8 | No Connect (NC) | Internally unused; must remain unconnected per TI specification to avoid parametric shift |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±1 pA typical - preserves signal integrity in high-impedance sensor interfaces (e.g., piezoelectric pickups) |
| Output Short-Circuit Protection | ±26 mA continuous - prevents latch-up or damage during accidental output shorts in test fixtures |
| EMI/RF Filtering | Integrated on-chip filters - suppresses 1 GHz RF interference in noisy industrial environments (53 dB EMIRR) |
| Wide Common-Mode Range | Extends to VCC+ - eliminates need for level-shifting in single-supply current-sense amplifier designs |
| Low THD+N | 0.00012% @ 1 kHz - preserves harmonic fidelity in audio signal paths without post-processing correction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | Same die, commercial temperature range (0°C to 70°C); higher max offset voltage (10 mV vs 1 mV typ) | Limited to benign environments like benchtop test gear; not rated for industrial ambient extremes | Select TL071CP only if cost sensitivity outweighs thermal stability and low-noise requirements |
| OPA1611AIDR | Lower noise (1.1 nV/√Hz), lower distortion (0.000015%), but higher quiescent current (3.6 mA) and narrower supply range (±2.25 V to ±18 V) | Preferred in ultra-high-fidelity audio where noise dominates; less suitable for battery-powered equipment due to power draw | Choose OPA1611AIDR when SNR >120 dB is mandatory and power budget allows ≥3× higher IQ |
Compared with TL071IPG4, TL071CP trades guaranteed low offset and extended temperature capability for lower cost, while OPA1611AIDR delivers superior noise and linearity at significantly higher power and price-making TL071IPG4 the optimal balance for industrial-grade audio and sensor signal chains requiring robustness and moderate performance.

FAQ
What is the maximum operating temperature range for TL071IPG4?
The TL071IPG4 is rated for operation from –40°C to +85°C ambient temperature. This industrial-grade temperature range ensures reliable performance in solar inverter enclosures, motor drive cabinets, and battery test chambers where ambient conditions exceed commercial limits. The device maintains specified offset drift (±2 µV/°C) and noise performance across this full span.
Does TL071IPG4 require external offset nulling in standard applications?
TL071IPG4 does not require external offset nulling in most applications. Its 1 mV typical input offset voltage is sufficient for AC-coupled audio paths and many DC-coupled sensor interfaces. Offset null pins (1 and 5) are provided only for ultra-precision DC applications demanding sub-100 µV error; omitting the trim network simplifies layout and improves long-term stability.
Can TL071IPG4 drive capacitive loads without oscillation?
Yes, TL071IPG4 is stable driving up to 300 pF capacitive loads with 56° phase margin and no external compensation. This capability supports direct connection to ADC input capacitors, coaxial cable runs, and multi-stage active filters. For loads exceeding 300 pF, a small series resistor (10–50 Ω) at the output restores stability without degrading bandwidth.
How does TL071IPG4 compare to TL071H in noise performance?
TL071IPG4 and TL071H share identical noise specifications: 37 nV/√Hz input voltage noise density at 1 kHz and 1.4 µVRMS integrated 0.1 Hz–10 Hz noise. Both use the same modern die fabrication process; the 'I' suffix denotes industrial temperature grade while 'H' indicates the newer high-performance variant-TL071IPG4 is functionally equivalent to TL071H in noise, slew rate, and GBW.
Is TL071IPG4 pin-compatible with other TL071 variants in PDIP packages?
Yes, TL071IPG4 is fully pin-compatible with all TL071x PDIP variants (e.g., TL071CP, TL071ACN, TL071BCN). All share identical 8-pin DIP footprint, pin numbering, and terminal functions-including NC on Pin 8 and offset null on Pins 1 and 5. This allows drop-in replacement across temperature grades without PCB redesign.
