Product details
Overview
TL061IP from Texas Instruments is a single-channel, low-power JFET-input 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 unity-gain bandwidth, 200 μA typical supply current per amplifier, and ±11 V common-mode input range extending to VCC+. It is used in battery-powered sensor interfaces and audio preamplifier stages where low quiescent power and high input impedance are critical.
For engineers reviewing the TL061IP datasheet, TL061IP pinout, TL061IP application, or TL061IP equivalent, key selection criteria include its JFET-input stage (1012 Ω input resistance), rail-to-rail-compatible common-mode range, low 30 nV/√Hz input voltage noise at 1 kHz, and SOIC-8/PDIP-8 package options - all validated for operation from –40°C to +85°C.
Technical Context
The TL061IP implements a fully differential JFET-input stage followed by a high-gain CMOS transconductance amplifier and class-AB output stage, enabling stable unity-gain operation without external compensation. Its internal frequency compensation ensures unconditional stability with capacitive loads up to 100 pF while maintaining 1 MHz bandwidth.
It supports dual-supply operation from ±5 V to ±15 V, features output short-circuit protection, and exhibits latch-up-free behavior under overvoltage transients. The device's high CMRR (80 dB min) and PSRR (80 dB min) make it suitable for noisy environments where supply ripple rejection and common-mode interference suppression are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA typical per amplifier - enables multi-stage analog chains in ultra-low-power systems without thermal or battery-life penalty. |
| Slew Rate | 3.5 V/µs typical - supports faithful reproduction of audio-band signals and fast-settling DC-coupled instrumentation outputs. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing filters, active RC networks, and closed-loop gain configurations up to G = 10 with phase margin > 45°. |
| Input Bias Current | 30 pA typical at 25°C - minimizes voltage error in high-impedance sensor interfaces (e.g., piezoelectric, photodiode, pH electrode). |
| Input Voltage Noise | 30 nV/√Hz at 1 kHz - lower than TL071 (42 nV/√Hz), improving SNR in low-level signal amplification below 10 kHz. |
| Common-Mode Range | –12 V to +15 V (with ±15 V supplies) - includes VCC+, allowing direct sensing of signals referenced to positive rail (e.g., high-side current sensing). |
| ESD Rating | 1.5 kV CDM - meets robustness requirements for automated PCB assembly and field-deployed equipment handling. |
Pinout & Package
TL061IP is available in PDIP-8 (Plastic Dual In-line Package, 9.59 mm × 7.94 mm) and SOIC-8 (Small Outline Integrated Circuit, 4.90 mm × 6.00 mm) packages. Pin functions are identical across both variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding permitted. |
| 2 | Inverting Input (IN–) | Differential input node; high-impedance JFET gate - sensitive to stray capacitance and EMI coupling. |
| 3 | Non-Inverting Input (IN+) | Differential input node; same impedance and noise characteristics as IN–; used for reference or signal injection. |
| 4 | VCC– | Negative supply terminal; must be decoupled locally with ≥0.1 µF ceramic capacitor to ground. |
| 5 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding permitted. |
| 6 | Output (OUT) | Class-AB buffered output capable of ±10 V swing into 10 kΩ load; short-circuit protected. |
| 7 | VCC+ | Positive supply terminal; must be decoupled locally with ≥0.1 µF ceramic capacitor to ground. |
| 8 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | 1012 Ω input resistance enables direct interfacing with megohm-range sensors without loading error. |
| Low power consumption | 200 µA supply current allows integration into multi-amplifier signal chains powered from coin cells or energy-harvesting sources. |
| Internal frequency compensation | Guarantees stable unity-gain operation without external components - reduces BOM count and layout sensitivity. |
| Output short-circuit protection | Prevents device failure during transient overloads or accidental wiring faults - eliminates need for external current-limiting resistors. |
| Latch-up free operation | Ensures reliable recovery after input overvoltage events beyond absolute maximum ratings - critical for ruggedized industrial designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | Higher slew rate (13 V/μs), higher supply current (2.5 mA), higher input voltage noise (18 nV/√Hz), same pinout and package. | Better for wideband audio or fast pulse amplification; unsuitable for sub-mA power budgets. | Select TL071CP only when bandwidth/speed outweighs power constraints; TL061IP remains preferred for battery longevity. |
| LM358AP | Bipolar input (20 nA bias current), lower input impedance (~2 MΩ), rail-to-rail output (not input), 700 kHz GBW, 0.6 V/μs slew rate. | Lower cost and wider temp range (–40°C to +105°C); insufficient for high-Z sensor buffering or precision DC gain. | Choose LM358AP for general-purpose low-speed, low-cost applications; TL061IP is mandatory when input bias current < 100 pA is required. |
Compared with TL071CP and LM358AP, TL061IP uniquely balances ultra-low power (200 µA), JFET-input performance (30 pA bias, 1012 Ω Zin), and industrial-grade temperature support (–40°C to +85°C), making it the optimal choice for precision analog front-ends where power and input impedance are co-constrained.

FAQ
What is the maximum supply voltage rating for TL061IP?
The TL061IP has an absolute maximum supply voltage rating of ±18 V (36 V total). However, the recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, even if within absolute max ratings. Always refer to the thermal derating curves in the datasheet for continuous operation at elevated voltages.
Does TL061IP support single-supply operation?
Yes, TL061IP supports single-supply operation with appropriate biasing. Its common-mode input range extends to VCC+, allowing the non-inverting input to be biased at mid-rail (e.g., VCC/2) using resistor dividers. Output swing is limited to approximately 1.5 V from each rail, so full-scale signal headroom must be planned accordingly in single-supply configurations.
What is the purpose of the NC pins on TL061IP?
Pins 1, 5, and 8 on TL061IP are No Connect (NC) terminals - they are not bonded internally and serve no electrical function. These pins must remain unconnected on the PCB; routing traces to them or tying them to ground/VCC may cause parasitic coupling or mechanical stress. Their presence accommodates die pad layout and package standardization across the TL06x family.
How does TL061IP compare to TL061CP in terms of temperature range?
TL061IP is rated for operation from –40°C to +85°C (industrial grade), while TL061CP is specified for 0°C to +70°C (commercial grade). Both share identical electrical specifications at 25°C, but TL061IP guarantees performance across the full industrial range - including input offset drift, slew rate, and CMRR - making it suitable for outdoor, automotive under-hood adjacent, and factory-floor deployments.
Is external compensation required for TL061IP in unity-gain configuration?
No, TL061IP includes internal frequency compensation optimized for stable unity-gain operation. External compensation capacitors are unnecessary and discouraged - adding them may degrade bandwidth and phase margin. The device is characterized and guaranteed to remain stable with capacitive loads up to 100 pF, as verified in Figure 6-6 of the datasheet.
