Product details
Overview
TL071CPSR 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, and ±13.5 V output swing into 10 kΩ at ±15 V supply - enabling high-fidelity preamplification in pro-audio mixers and sensor front-ends.
For engineers reviewing the TL071CPSR datasheet, TL071CPSR pinout, TL071CPSR application, or TL071CPSR equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (≤200 pA), offset voltage of 3–10 mV (typ), CMRR of 70–100 dB, and SO package compatibility with industrial temperature range (0°C to +70°C).
Technical Context
The TL071CPSR uses a dual-JFET input stage with high-impedance differential pair and Class AB output stage, supporting rail-to-rail common-mode input up to VCC+ (with headroom). Its internal compensation ensures unity-gain stability with capacitive loads ≤300 pF and provides 56° phase margin at G = +1.
Designed for DC-coupled and AC-coupled amplification, it operates from ±2.25 V to ±20 V supplies (4.5 V to 40 V total), features output short-circuit protection, and maintains 125 dB open-loop gain (min) across its specified temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.25 MHz - supports stable unity-gain buffers and 10× amplifiers up to ~500 kHz |
| Slew rate | 8–20 V/μs - enables clean reproduction of 10 Vpp signals up to ~125 kHz without slew-induced distortion |
| Input voltage noise density | 37 nV/√Hz @ 1 kHz - critical for low-level microphone and piezoelectric sensor amplification |
| Input bias current | 65–200 pA - preserves signal integrity in high-impedance transducer interfaces (e.g., photodiode, pH electrode) |
| Common-mode rejection ratio | 70–100 dB - suppresses power-supply ripple and ground-bounce interference in noisy industrial environments |
| Supply voltage range | ±2.25 V to ±20 V (4.5 V to 40 V total) - compatible with legacy ±15 V systems and modern low-voltage rails |
| Offset voltage | 3–10 mV (typ) - sets minimum resolvable DC signal level in precision instrumentation |
Pinout & Package
TL071CPSR is housed in an 8-pin SO (Small Outline) package (PS), measuring 4.9 mm × 3.9 mm × 1.75 mm, with gull-wing leads and standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Input offset null adjustment terminal - used with external potentiometer to trim DC error to <1 mV |
| 2 | IN− | Inverting input - accepts feedback network for stable closed-loop gain configurations |
| 3 | IN+ | Noninverting input - high-impedance node (≥1 TΩ) for direct sensor connection or reference biasing |
| 4 | VCC− | Negative supply rail - must be decoupled locally with ≥0.1 μF ceramic capacitor |
| 5 | OFFSET N2 | Input offset null adjustment terminal - completes external trimming circuit with Pin 1 |
| 6 | OUT | Amplified output - capable of sourcing/sinking ±26 mA, with 115–210 mV headroom from positive rail |
| 7 | VCC+ | Positive supply rail - supports wide dynamic range operation up to ±20 V |
| 8 | NC | No connect - internally unconnected; must remain floating per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables ≤200 pA input bias current - essential for integrating high-Z sensors without loading error |
| Low 1/f noise | 1.4 µVRMS (0.1 Hz–10 Hz) - minimizes drift and audible hiss in DC-coupled audio paths |
| Output short-circuit protection | Withstands indefinite short to ground - improves system robustness in field-deployed equipment |
| Wide common-mode input range | Extends to VCC+ - allows direct interface with rail-referenced signals (e.g., DAC outputs, thermocouple cold-junction refs) |
| EMI rejection ratio | 53 dB @ 1 GHz - mitigates RF ingress in mixed-signal PCBs near switching regulators or wireless modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071IP | Same electrical specs but in 8-pin PDIP package; no offset null pins; wider lead pitch (0.3 inch vs 0.05 inch) | Prototyping and through-hole assembly only; lacks SO package thermal performance and board space efficiency | Select TL071IP only for breadboard evaluation or legacy through-hole designs requiring manual soldering |
| OPA134UA | Lower noise (8 nV/√Hz), lower distortion (0.00008% THD+N), higher slew rate (20 V/μs), but higher quiescent current (4 mA/ch) and cost | High-end audio and metrology where noise and linearity outweigh power budget constraints | Choose OPA134UA when SNR >115 dB and THD+N < –110 dB are required; TL071CPSR remains optimal for cost-sensitive industrial signal chains |
Compared with TL071IP and OPA134UA, TL071CPSR offers the best balance of low-noise FET input performance, SO-package manufacturability, and offset-trimming capability - making it ideal for volume production of audio and test equipment where DC accuracy and EMI resilience matter.

FAQ
What is the operating temperature range for TL071CPSR?
The TL071CPSR is rated for operation from 0°C to +70°C ambient temperature, matching the 'C' grade specification defined in TI's datasheet Section 5.3. This makes it suitable for commercial and industrial indoor applications but not extended-temperature environments like automotive under-hood or outdoor power electronics. Always verify thermal derating when operating near maximum junction temperature limits.
Does TL071CPSR support rail-to-rail input or output?
TL071CPSR supports rail-to-rail common-mode input - its input range extends to VCC+, though it does not reach VCC− (minimum is VCC− + 1.5 V). Output swing is not rail-to-rail: at ±15 V supply and 10 kΩ load, it delivers ±13.5 V (1.5 V headroom from each rail). For true rail-to-rail operation, consider newer alternatives like OPA376 or TLV2462.
How do I use the OFFSET N1 and OFFSET N2 pins on TL071CPSR?
Connect a 10 kΩ potentiometer between OFFSET N1 (Pin 1) and OFFSET N2 (Pin 5), with the wiper grounded. Adjusting the potentiometer nulls input offset voltage to <1 mV - critical for DC-coupled precision applications like strain gauge bridges or thermocouple amplifiers. Do not leave these pins floating; unused terminals must be tied as specified in TI SLOS080W Figure 4-4.
Can TL071CPSR drive capacitive loads?
Yes, TL071CPSR can safely drive capacitive loads up to 300 pF while maintaining stability and 56° phase margin, per datasheet Section 5.7. For larger loads (e.g., long cables or ADC input filters), add a series isolation resistor (10–100 Ω) between output and capacitance to prevent peaking or oscillation. Avoid direct connection to >500 pF without external compensation.
What is the difference between TL071CPSR and TL071HPSR?
TL071CPSR uses the legacy silicon process ('C' grade), with typical offset voltage of 3–10 mV and 37 nV/√Hz noise. TL071HPSR uses TI's newer 'H'-suffix die, offering improved specs: 1 mV typical offset, 20 V/μs slew rate (vs 8–20 V/μs), and enhanced ESD robustness (2 kV HBM). Both share the PS SO package and pinout, but H-grade is preferred for new designs demanding tighter DC accuracy.
