Product details
Overview
TL071ACP 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 high fidelity and DC accuracy are critical.
For engineers reviewing the TL071ACP datasheet, TL071ACP pinout, TL071ACP application, or TL071ACP equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±1 pA typ), offset voltage drift of ±2 μV/°C, and guaranteed operation across 0°C to 70°C industrial temperature range - all in an 8-pin PDIP package with offset-null capability.
Technical Context
The TL071ACP uses a high-impedance JFET differential pair input stage enabling sub-picoampere input bias current and wide common-mode range including VCC+. Its internal compensation ensures unity-gain stability with 5.25 MHz gain-bandwidth product and 56° phase margin under standard 10 kΩ/20 pF load conditions.
It features integrated EMI filtering, output short-circuit protection, and low THD+N (0.00012% typ at 1 kHz), making it suitable for high-fidelity signal paths. The device supports dual ±15 V operation and maintains 118 dB open-loop gain and 100 dB CMRR over temperature.
Key Specifications

| Input Voltage Noise | 37 nV/√Hz at 1 kHz - supports low-noise preamplifier stages in audio and sensor interfaces |
| Input Bias Current | ±1 pA typical - preserves signal integrity in high-impedance source networks (e.g., piezoelectric sensors) |
| Offset Voltage Drift | ±2 μV/°C - ensures stable DC accuracy over 0°C–70°C operating range without recalibration |
| Supply Voltage Range | ±2.25 V to ±20 V - accommodates legacy ±15 V systems and modern low-voltage designs |
| Common-Mode Input Range | Includes VCC+ - allows direct interface with signals referenced to positive rail (e.g., current-sense amps) |
| Open-Loop Gain | 118 dB - provides >750,000 V/V loop gain for precise closed-loop gain setting and error reduction |
Pinout & Package
TL071ACP is housed in an 8-pin plastic dual in-line package (PDIP) with through-hole mounting. Pin 1 is OFFSET N1 (input offset null), Pin 2 is IN–, Pin 3 is IN+, Pin 4 is VCC–, Pin 5 is OFFSET N2 (input offset null), Pin 6 is OUT, Pin 7 is VCC+, and Pin 8 is NC (no connect).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Adjustment terminal for fine-tuning input offset voltage via external potentiometer |
| 2 | IN– | Inverting input - primary feedback node in standard op-amp configurations |
| 3 | IN+ | Noninverting input - accepts reference or signal input in follower/buffer applications |
| 4 | VCC– | Negative supply rail - must be connected to system ground or negative voltage |
| 5 | OFFSET N2 | Second offset adjustment terminal - used with Pin 1 to balance input stage mismatch |
| 6 | OUT | Amplified output - capable of sourcing/sinking ±26 mA with 210 mV headroom from rails |
| 7 | VCC+ | Positive supply rail - supports up to +20 V; common-mode input extends to this pin |
| 8 | NC | No connect - internally unconnected; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | Same die, commercial temperature range (0°C to 70°C), identical pinout and electrical specs | No difference - direct functional replacement with identical performance in non-extended temp environments | Select TL071CP when full military-grade screening or extended temperature qualification is unnecessary |
| OPA134PA | Lower noise (8 nV/√Hz), higher slew rate (20 V/μs), wider GBW (8 MHz), but no offset-null pins | Lacks offset trim capability - unsuitable where manual calibration is required for sub-mV DC accuracy | Choose OPA134PA for ultra-low-noise audio paths where offset drift is managed digitally or via auto-zeroing |
Compared with TL071CP and OPA134PA, TL071ACP offers unique offset-null terminals for analog trimming in precision DC-coupled circuits, while maintaining industry-standard JFET-input noise and bias performance - a critical differentiator for calibrated test equipment and legacy audio designs.

FAQ
What is the maximum supply voltage for TL071ACP?
The TL071ACP supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V). Absolute maximum ratings specify 42 V for non-NS/PS packages, but recommended operation is capped at ±20 V to ensure reliability and specified performance across temperature.
Does TL071ACP have rail-to-rail input or output capability?
The TL071ACP features rail-to-rail common-mode input range - its input stage operates with common-mode voltages extending to VCC+ - but output swing is not rail-to-rail. At ±15 V supplies and 10 kΩ load, output typically swings within 210 mV of each rail.
How do I use the offset null pins on TL071ACP?
Pins 1 (OFFSET N1) and 5 (OFFSET N2) connect to the ends of a 10 kΩ potentiometer; the wiper connects to VCC–. Adjusting the potentiometer balances input stage mismatches, reducing input offset voltage to <100 μV - essential for precision DC-coupled amplifiers using TL071ACP.
Is TL071ACP suitable for single-supply operation?
Yes - TL071ACP operates with single supplies as low as +4.5 V. Its common-mode input range includes the positive rail, allowing input signals referenced to VCC. However, output cannot swing to VCC– (ground), so a virtual ground or level-shifting network may be needed for true single-supply signal handling.
What is the typical input bias current of TL071ACP at 25°C?
The TL071ACP exhibits a typical input bias current of ±1 pA at 25°C, with a maximum of ±120 pA across the 0°C to 70°C temperature range. This ultra-low value stems from its JFET-input architecture and makes TL071ACP ideal for high-impedance sensor interfaces.
