Product details
Overview
TL071CDE4 from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 37 nV/√Hz input voltage noise at 1 kHz, 5.25 MHz gain-bandwidth product, ±15 V supply operation, and 0.003% THD+N - making it suitable for pro-audio mixers and battery test equipment where fidelity and DC stability are critical.
For engineers reviewing the TL071CDE4 datasheet, TL071CDE4 pinout, TL071CDE4 application, or TL071CDE4 equivalent, key selection criteria include its FET-input architecture enabling pA-level bias current, rail-to-rail common-mode input (including VCC+), output short-circuit protection, and SOIC-8 packaging compatible with industrial PCB layouts requiring thermal reliability and EMI resilience.
Technical Context
The TL071CDE4 implements a high-slew-rate (20 V/μs) JFET differential input stage followed by a Class AB output stage, supporting stable unity-gain operation with up to 300 pF capacitive load. Its internal compensation ensures phase margin ≥56° under standard test conditions (G = +1, RL = 10 kΩ, CL = 20 pF).
Designed for the TL07xC grade, it operates across 0°C to +70°C ambient temperature, with DC specifications including 3–10 mV input offset voltage, ±18 μV/°C drift, and 70–100 dB CMRR at ±15 V supply - distinguishing it from the higher-performance TL071H variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2.25 V to ±20 V (4.5 V to 40 V); supports dual-rail and single-supply configurations in analog front-ends. |
| Gain-Bandwidth Product | 5.25 MHz; enables stable closed-loop operation up to ~100 kHz at G = 50 without external compensation. |
| Slew Rate | 20 V/μs; preserves transient fidelity in fast-settling instrumentation and audio preamp stages. |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz; low enough for microphone preamplifiers and sensor signal chains requiring sub-μV resolution. |
| Input Bias Current | 65–200 pA (typ); enables high-impedance source interfacing (e.g., piezoelectric sensors, photodiode TIA feedback networks). |
| THD+N | 0.003% at 1 kHz, 6 VRMS output; meets pro-audio line-level distortion requirements without post-filtering. |
| Common-Mode Input Range | Includes VCC+; allows direct sensing of signals referenced to positive rail (e.g., high-side current monitoring). |
Pinout & Package
TL071CDE4 is supplied in an 8-pin SOIC (PS) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Pin 1 is OFFSET N1 for input offset nulling; Pin 5 is OFFSET N2. Power pins are isolated from signal paths to minimize supply coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Input offset voltage adjustment terminal; connects to potentiometer wiper for precision DC calibration. |
| 2 | IN− | Inverting input; high-impedance JFET node for feedback network connection in inverting amplifiers. |
| 3 | IN+ | Noninverting input; accepts high-Z sources directly; common-mode range extends to VCC+. |
| 4 | VCC− | Negative supply rail; must be decoupled locally to suppress ground bounce in multi-amplifier systems. |
| 5 | OFFSET N2 | Second offset null terminal; completes 3-terminal potentiometer circuit for symmetric nulling. |
| 6 | OUT | Class AB output stage; drives ≥2 kΩ loads to ±10 V swing; short-circuit protected. |
| 7 | VCC+ | Positive supply rail; supports rail-to-rail input common-mode and wide dynamic range. |
| 8 | NC | No connect; electrically isolated; no internal bond wire or silicon connection. |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | 65–200 pA enables use with >100 MΩ source impedances without significant DC error. |
| Output short-circuit protection | Self-limiting current prevents latch-up or destruction during accidental output shorts. |
| Wide supply voltage range | ±2.25 V to ±20 V accommodates legacy ±15 V systems and modern low-voltage battery-powered designs. |
| High CMRR (70–100 dB) | Rejects power supply ripple and shared-impedance noise in mixed-signal PCB environments. |
| EMI rejection ratio | 53 dB at 1 GHz reduces susceptibility to RF interference in noisy industrial enclosures. |

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 electrical specs and SOIC-8 pinout; PDIP-8 package instead of SOIC-8; higher thermal resistance (85°C/W vs 95°C/W). | Preferred for through-hole prototyping or legacy board rework where SOIC footprint unavailable. | Select TL071CP only when manual soldering or socket-based testing is required. |
| OPA134UA | Lower noise (8 nV/√Hz), lower distortion (0.00008% THD+N), but higher quiescent current (4 mA vs 1.4–2.5 mA) and narrower supply range (±4.5 V to ±18 V). | Better suited for ultra-low-noise studio-grade audio, not cost-sensitive industrial monitoring. | Choose OPA134UA only when noise performance outweighs power budget and BOM cost constraints. |
Compared with TL071CP and OPA134UA, TL071CDE4 offers optimal balance of low noise, low power, SOIC-8 manufacturability, and proven reliability in industrial analog signal chains - especially where cost, thermal management, and legacy compatibility are prioritized over absolute noise floor.

FAQ
What is the maximum operating temperature range for TL071CDE4?
The TL071CDE4 is rated for operation from 0°C to +70°C ambient temperature, consistent with its TL07xC grade designation. This makes it suitable for commercial and industrial indoor applications but not extended-temperature environments like automotive under-hood or military systems - for which TL071H (–40°C to +125°C) or TL071M (–55°C to +125°C) variants are specified. Always verify thermal derating against PCB layout and power dissipation in final design.
Does TL071CDE4 support rail-to-rail input or output?
TL071CDE4 supports rail-to-rail common-mode input - its input voltage range extends to VCC+, enabling high-side sensing - but does not provide rail-to-rail output swing. Typical output swing is ±12 V into 10 kΩ at ±15 V supply, with 105–215 mV headroom from each rail. For true rail-to-rail I/O, consider newer alternatives like OPA333 or TLV2461, though these lack the TL071CDE4's JFET input noise profile and legacy compatibility.
Can TL071CDE4 be used in single-supply configurations?
Yes, TL071CDE4 operates in single-supply mode with VCC− grounded and VCC+ at +4.5 V to +40 V. Its input common-mode range includes the positive rail, allowing input signals referenced to VCC+. However, output swing remains asymmetric: typical high-side swing is limited to ~VCC+ – 0.1 V, while low-side swing reaches ~0.1 V above ground. Proper biasing (e.g., mid-rail reference) is required for AC-coupled signal paths.
What is the purpose of Pins 1 and 5 (OFFSET N1/N2) on TL071CDE4?
Pins 1 and 5 on TL071CDE4 are dedicated input offset voltage nulling terminals. Connecting a 10-kΩ potentiometer between them, with its wiper tied to VCC−, allows precise cancellation of DC input offset (typically 3–10 mV). This is essential in DC-coupled applications like precision integrators or strain gauge amplifiers where even millivolt-level offsets cause integration drift or measurement error over time.
How does TL071CDE4 compare to TL071H in terms of noise and offset performance?
TL071CDE4 (TL07xC grade) specifies 37 nV/√Hz input voltage noise at 1 kHz - identical to TL071H - but exhibits higher input offset voltage (3–10 mV vs ±1 mV typ for TL071H) and greater drift (±18 μV/°C vs ±2 μV/°C). The TL071H also features improved PSRR and CMRR, wider temperature range (–40°C to +125°C), and lower quiescent current (937–1125 μA vs 1.4–2.5 mA). TL071CDE4 trades precision for cost and legacy compatibility.
