Product details
Overview
TL061CDT from STMicroelectronics is a low-power JFET-input single operational amplifier designed for precision analog signal conditioning in cost-sensitive industrial and consumer systems. It delivers 3.5 V/µs slew rate, 1 MHz gain-bandwidth product, ±15 V input common-mode range (up to VCC+), and consumes only 200 µA quiescent current - enabling battery-powered sensor front-ends and portable instrumentation.
For engineers reviewing the TL061CDT datasheet, TL061CDT pinout, TL061CDT application, or TL061CDT equivalent, key selection criteria include its JFET-input high input impedance (1012 Ω), low input bias current (30 pA typ.), output short-circuit protection, and SO-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TL061CDT uses a monolithic JFET-bipolar hybrid process to achieve high input impedance and low input currents while maintaining robust output drive capability. Its internal frequency compensation ensures unity-gain stability without external components across supply voltages from ±3 V to ±18 V.
It operates over 0°C to +70°C ambient temperature, supports rail-to-rail input common-mode range (±11 V to +15 V / –12 V), and provides 20 V peak-to-peak output swing into 10 kΩ at ±15 V supplies - making it suitable for single-supply and dual-supply configurations in transducer amplification and active filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA typical - enables multi-channel low-power sensor interfaces with minimal thermal load |
| Slew Rate | 3.5 V/µs - supports audio-band signal amplification and medium-speed pulse conditioning |
| Input Bias Current | 30 pA typical - preserves signal integrity in high-impedance source applications (e.g., piezoelectric sensors) |
| Input Resistance | 1012 Ω - minimizes loading error on passive RC networks and high-Z transducers |
| Common-Mode Range | ±11 V to +15 V / –12 V - allows direct interfacing with signals near supply rails in single-ended configurations |
| Gain-Bandwidth Product | 1 MHz - sets usable closed-loop bandwidth limit for gain ≥10 configurations |
| Output Short-Circuit Duration | Infinite - permits safe operation during transient overload or wiring faults without latch-up |
Pinout & Package
TL061CDT is housed in an SO-8 plastic micropackage (ECOPACK® compliant), measuring 4.90 mm × 6.00 mm × 1.75 mm (max height), with 1.27 mm pitch gull-wing leads. Thermal resistance junction-to-ambient is 125 °C/W (SO-8).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset null (1) | Connects to external potentiometer wiper for input offset voltage trimming |
| 2 | Inverting input | Primary negative feedback node; accepts inverted-phase signal or reference |
| 3 | Non-inverting input | Positive input terminal; used in follower, summing, or differential configurations |
| 4 | VCC– | Negative supply rail connection; must be referenced to system ground or negative rail |
| 5 | Offset null (2) | Second terminal of offset trim network; completes nulling circuit with Pin 1 |
| 6 | Output | Amplified single-ended output; capable of sourcing/sinking up to ±20 mA (short-circuit protected) |
| 7 | VCC+ | Positive supply rail connection; supports up to +18 V absolute maximum rating |
| 8 | No connect (N.C.) | Internally unconnected; must remain floating - no external tie required |
Key Features
| Feature | Design Value |
|---|---|
| Very low power consumption | 200 µA supply current enables >1-year battery life in always-on sensor nodes |
| High input impedance JFET stage | 1012 Ω input resistance prevents signal attenuation in megohm-level source impedances |
| Internal frequency compensation | Unity-gain stable without external compensation capacitors - reduces BOM count and layout complexity |
| Output short-circuit protection | Allows indefinite short to either rail or ground without damage - critical for field-deployed equipment safety |
| Latch-up free operation | Guaranteed immunity to CMOS-like latch-up under overvoltage or ESD stress conditions |
Applications
| Industrial Sensor Signal Conditioning | Portable Instrumentation Amplifiers |

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 | Higher slew rate (13 V/µs), lower input noise (18 nV/√Hz), but higher supply current (2.8 mA) | Better suited for wideband audio or fast transient response; not viable for microamp-level power budgets | Select when speed/noise outweigh power constraints; avoid in battery-operated designs |
| CA3140EZ | BiMOS input stage, 0.5 pA input bias current, but slower slew rate (9 V/s) and no SO-8 option | Preferred for femtoamp-level sensor interfaces (e.g., photodiode TIA); lacks rail-swing capability | Choose for ultra-low Iib where speed is secondary; verify DIP8-only availability impacts layout |
Compared with TL061CDT, TL071CP trades 14× higher supply current for 3.7× faster slew rate and halved noise, while CA3140EZ offers 60× lower input bias current but sacrifices bandwidth and modern packaging - making TL061CDT optimal for balanced low-power, medium-speed precision use cases.

FAQ
What is the maximum supply voltage for TL061CDT?
The absolute maximum supply voltage is ±18 V (36 V total). Operation beyond this risks permanent damage. For reliable long-term use, ST recommends staying within ±15 V, especially at elevated temperatures, to maintain specified slew rate and output swing performance.
Does TL061CDT require external compensation capacitors?
No - TL061CDT features internal frequency compensation and is unity-gain stable across all standard configurations. Adding external compensation may degrade phase margin and cause instability; it is neither required nor recommended per the datasheet.
Can TL061CDT operate from a single +5 V supply?
Yes, but with limitations: input common-mode range extends only to VCC– +1.5 V and VCC+ –1.5 V, so with +5 V supply, usable input range is ~0.5 V to 4.5 V. Output swing is similarly constrained to ~1.5 V to 3.5 V into 10 kΩ, requiring careful biasing for AC-coupled signals.
Is the SO-8 package of TL061CDT RoHS and REACH compliant?
Yes - TL061CDT carries ECOPACK®2 certification, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The SO-8 package uses lead-free terminations and halogen-free molding compound, verified per STMicroelectronics' published environmental compliance documentation.
