Product details
Overview
TL080CPS from Texas Instruments is a JFET-input operational amplifier designed for precision analog signal conditioning in dual-supply systems. It delivers 13 V/µs typical slew rate, ±15 V supply capability, 3 MHz unity-gain bandwidth, and 0.003% typical total harmonic distortion at 1 kHz - enabling high-fidelity audio preamplification and sensor signal amplification in industrial instrumentation.
For engineers reviewing the TL080CPS datasheet, TL080CPS pinout, TL080CPS application, or TL080CPS equivalent, key selection criteria include input bias current (≤400 pA typ), common-mode input range extending to VCC+, offset voltage nulling capability, and external frequency compensation support for stability-critical feedback designs.
Technical Context
The TL080CPS integrates matched high-voltage JFET and bipolar transistors to achieve low input bias current and high input impedance (10¹² Ω). Its internal architecture supports external compensation via pins 1 and 5 (N1/COMP and COMP), allowing precise control of gain-bandwidth trade-offs across varying load and capacitance conditions.
It operates over 0°C to 70°C with ±15 V supplies, features latch-up-free design, and provides output short-circuit protection. The device's differential input stage accepts ±30 V differential voltage and ±15 V absolute input voltage, with common-mode range spanning −12 V to +15 V - making it suitable for rail-to-rail input signal handling in non-inverting configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 13 V/µs typical - enables faithful reproduction of fast-changing signals up to ~1 MHz without slew-induced distortion |
| Unity-Gain Bandwidth | 3 MHz - supports stable closed-loop operation at gains ≥1 with adequate phase margin using external compensation |
| Input Bias Current | 30–400 pA at 25°C - minimizes DC error in high-impedance sensor interfaces and integrator circuits |
| Input Offset Voltage | 3–15 mV at 25°C - adjustable via external potentiometer between pins 1 and 5 for sub-mV precision |
| Total Harmonic Distortion | 0.003% typical at 1 kHz - meets requirements for low-noise audio preamp and measurement-grade signal chains |
| Common-Mode Input Range | −12 V to +15 V - allows input signals to swing beyond negative rail, supporting single-ended sensor outputs referenced to ground |
| Supply Voltage Range | ±3 V to ±18 V - accommodates legacy ±15 V systems and lower-power ±5 V designs with headroom margin |
Pinout & Package
TL080CPS is housed in an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Thermal resistance θJA is 85°C/W, supporting continuous operation at ambient temperatures up to 70°C with appropriate PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (IN−) | Inverting input | High-impedance JFET gate node; accepts differential input signals up to ±30 V |
| 3 (IN+) | Non-inverting input | High-impedance JFET gate node; common-mode range includes VCC+ |
| 4 (VCC−) | Negative supply rail | Reference for internal biasing; must be connected to system ground or negative supply |
| 5 (COMP) | Compensation terminal | Used with Pin 1 to configure external frequency compensation network for stability optimization |
| 6 (OUT) | Amplifier output | Capable of driving ≥2 kΩ loads; protected against indefinite short-circuit to either supply rail |
| 7 (VCC+) | Positive supply rail | Supplies internal circuitry; supports up to +18 V with thermal derating |
| 8 (OFFSET N2) | Offset null connection | Completes offset adjustment path with Pin 1; tied to one end of external 10–20 kΩ potentiometer |
Key Features
| Feature | Design Value |
|---|---|
| JFET input stage | Delivers 10¹² Ω input impedance and ≤400 pA input bias current - critical for photodiode, piezoelectric, and high-Z sensor interfacing |
| External frequency compensation | Enables customizable gain-bandwidth product and phase margin tuning via Pins 1 and 5 - essential for driving capacitive loads or achieving wideband stability |
| Output short-circuit protection | Allows indefinite output shorting to VCC+ or VCC− without damage - improves robustness in test equipment and industrial control I/O stages |
| Offset voltage nulling | Supports sub-mV DC accuracy via external potentiometer between Pins 1 and 8 - required for precision integrators and low-drift instrumentation amplifiers |
| Latch-up-free operation | Prevents destructive parasitic conduction under overvoltage or ESD stress - enhances reliability in unregulated or noisy power environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | Lower input bias current (65 pA typ), higher slew rate (16 V/µs), same pinout and package | Better suited for ultra-high-Z sources and faster settling; not rated for >125°C ambient | Select TL071CP when lower noise and faster response are prioritized over cost and legacy compatibility |
| LF356N | Higher input offset voltage (10 mV max), no offset null pins, identical supply range and bandwidth | Less suitable for precision DC-coupled stages but more tolerant of layout-induced parasitics | Choose LF356N where simplicity and ruggedness outweigh need for fine offset trimming |
Compared with TL080CPS, TL071CP offers superior speed and input current performance at similar cost, while LF356N trades offset adjustability for reduced external component count - making TL080CPS optimal for legacy designs requiring field calibration and proven thermal stability over 0°C–70°C.

FAQ
What is the operating temperature range for TL080CPS?
The TL080CPS is characterized for operation from 0°C to 70°C. This commercial-grade rating aligns with its "C" suffix designation and ensures specified electrical performance-including input offset voltage (≤15 mV), slew rate (≥8 V/µs), and CMRR (≥70 dB)-within that ambient range. Operation outside this range may result in parametric degradation or reliability risk.
Does TL080CPS support single-supply operation?
TL080CPS is optimized for dual-supply operation (e.g., ±15 V), but can function in single-supply configurations with proper biasing. Its common-mode input range extends to VCC+, allowing inputs near the positive rail; however, the negative rail (VCC−) must remain at a defined potential-typically ground-so true single-supply use requires level-shifting networks. The TL080CPS does not support rail-to-rail input or output.
How do I configure external frequency compensation for TL080CPS?
External compensation for TL080CPS uses Pins 1 (N1/COMP) and 5 (COMP) to connect a capacitor (e.g., 18 pF for unity-gain stability with 2 kΩ load) between them, or a capacitor-resistor network from Pin 5 to VCC−. Figure 1 in the SLOS368 datasheet shows the standard unity-gain configuration. Compensation value depends on closed-loop gain, load capacitance, and desired phase margin-TI's application notes provide design equations and stability plots specific to TL080CPS.
Can TL080CPS drive capacitive loads directly?
TL080CPS is not inherently stable driving pure capacitive loads >100 pF without external compensation. Its internal compensation is optimized for resistive loads; driving cables or ADC input capacitance requires adding a series resistor (e.g., 100 Ω) in the feedback path or configuring external compensation via Pins 1 and 5. Figure 3 in the SLOS368 datasheet demonstrates feed-forward compensation for improved capacitive-load drive capability.
Is TL080CPS RoHS compliant?
TL080CPS was manufactured under legacy processes and is marked as OBSOLETE by Texas Instruments. While many PDIP-packaged variants (including TL080CP) were produced with leaded finishes, RoHS compliance status is not documented in the SLOS368 datasheet or TI's 2015 packaging addendum. For new designs, TI recommends evaluating RoHS-compliant alternatives such as TL071 or OPA167x series - TL080CPS should only be sourced for legacy repair or continuity programs with verified material declarations.
