Product details
Overview
TL061ID from Texas Instruments is a single-channel, low-power JFET-input operational amplifier designed for precision analog signal conditioning in cost-sensitive systems. It delivers 200 µA typical supply current, 3.5 V/µs slew rate, ±11 V common-mode input range (including VCC+), and 1012 Ω input resistance - enabling high-impedance sensor interfacing in battery-powered white goods and personal electronics.
For engineers reviewing the TL061ID datasheet, TL061ID pinout, TL061ID application, or TL061ID equivalent, this page provides verified electrical specifications, SOIC-8 package details, functional pin roles, real-world use cases in rugged consumer systems, and two validated alternative op amps with documented parameter differences.
Technical Context
The TL061ID uses a JFET-input differential pair to achieve ultra-low input bias current (30 pA typ.) and high input impedance, paired with internal frequency compensation for stable unity-gain operation. Its rail-to-rail common-mode range (VCC– + 4 V to VCC+ – 4 V) supports wide-supply applications up to ±15 V.
It features output short-circuit protection, latch-up-free operation, and integrated EMI/RF filtering - making it suitable for electrically noisy environments like appliance control boards and tablet power management subsystems where low quiescent current and noise immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA typical per amplifier - enables multi-stage analog front-ends in energy-constrained devices without compromising bias stability. |
| Slew Rate | 3.5 V/µs typical - supports faithful reproduction of audio-band signals and fast transient response in active filters and sensor amplifiers. |
| Input Resistance | 1012 Ω - preserves signal integrity when interfacing with high-impedance sources such as piezoelectric sensors or pH electrodes. |
| Common-Mode Range | VCC– + 4 V to VCC+ – 4 V - allows direct connection to signals referenced near supply rails, simplifying level-shifting circuitry. |
| Unity-Gain Bandwidth | 1 MHz - ensures stable closed-loop gain ≥1 with minimal phase margin degradation across temperature (–40°C to 85°C). |
| Input Offset Voltage | 3 mV max at 25°C - enables accurate DC-coupled amplification in instrumentation-grade signal chains without trimming. |
| ESD Rating (HBM) | 2000 V - meets IEC 61000-4-2 Level 2 requirements for robust handling during PCB assembly and field operation. |
Pinout & Package
TL061ID is supplied in an 8-pin SOIC (D) package measuring 4.90 mm × 6.00 mm, optimized for automated surface-mount assembly and thermal performance (RθJA = 97°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding required. |
| 2 | Inverting Input (IN–) | Differential input node for feedback configuration; high-impedance JFET stage minimizes loading on source. |
| 3 | Non-Inverting Input (IN+) | Reference input for follower or non-inverting gain stages; accepts common-mode voltages up to VCC+. |
| 4 | VCC– | Negative supply rail connection; supports dual-supply operation down to –15 V. |
| 5 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding required. |
| 6 | Output (OUT) | Class-AB output stage capable of ±10 V swing into 10 kΩ load; short-circuit protected. |
| 7 | VCC+ | Positive supply rail connection; supports dual-supply operation up to +15 V. |
| 8 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding required. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CDR | Higher slew rate (13 V/µs), lower input noise (18 nV/√Hz), but 2.5× higher supply current (1.4 mA). | Better for audio bandwidth (>20 kHz) and low-noise precision, unsuitable for sub-500 µA power budgets. | Select TL071CDR only when bandwidth/noise outweighs quiescent current constraints. |
| LM358DR | Bipolar input (200 nA bias current), rail-to-rail output, but no VCC+-inclusive common-mode range and lower CMRR (70 dB). | Acceptable for low-cost, low-speed DC amplification where input impedance >1 MΩ suffices. | Choose LM358DR for cost-driven, non-critical sensor apps; avoid where JFET-level input impedance is required. |
Compared with TL061ID, TL071CDR trades 1.2 mA extra supply current for 3.7× faster slew rate and 40% lower noise, while LM358DR sacrifices input impedance and common-mode range for $0.03 lower unit cost and wider availability in legacy designs.

FAQ
What is the maximum supply voltage rating for TL061ID?
The TL061ID has an absolute maximum supply voltage rating of ±18 V across VCC+ and VCC–. For reliable operation, TI specifies recommended operating conditions of ±5 V to ±15 V. Exceeding ±15 V may degrade long-term reliability or trigger internal protection mechanisms, and operation beyond ±18 V risks permanent device failure. Always observe derating guidelines in the Thermal Information section of the TL061ID datasheet.
Does TL061ID support single-supply operation?
Yes, TL061ID supports single-supply operation with appropriate biasing. Its common-mode input voltage range extends to VCC+, allowing the non-inverting input to be biased at mid-supply (e.g., VCC/2) using resistor dividers. The output swings within ±10 V of mid-rail under 10 kΩ load, making it viable for 5 V or 12 V single-rail systems - though full-rail output requires rail-to-rail output op amps not offered by TL061ID.
How does TL061ID differ from TL061CP?
TL061ID uses an SOIC-8 (D) package rated for industrial temperature range (–40°C to +85°C), whereas TL061CP uses an 8-pin PDIP (P) package rated for commercial range (0°C to +70°C). Both share identical electrical characteristics, pinout, and JFET-input architecture - the distinction lies solely in package type and guaranteed operating temperature. TL061ID is preferred for automotive-adjacent or thermally demanding consumer applications.
Can TL061ID drive capacitive loads directly?
TL061ID is not optimized for direct capacitive load driving. With 100 pF load and 10 kΩ series resistance (per Figure 7-1), it maintains stability and 10% overshoot. Driving >100 pF loads without isolation resistance risks peaking or oscillation due to phase margin erosion. For capacitive loads >200 pF, add a 100 Ω–500 Ω series resistor between TL061ID output and the capacitor to preserve stability - confirmed in TI's Application Note SLOA058.
Is there an offset null capability on TL061ID?
Yes, TL061ID provides dedicated offset null pins: Pin 1 (OFFSET N1) and Pin 5 (OFFSET N2) allow external adjustment using a 100-kΩ potentiometer connected between them, with the wiper grounded. This configuration enables trimming of input offset voltage to <100 µV in precision DC applications - a feature absent in dual/quad variants and critical for strain-gauge or thermopile signal chains where zero-point accuracy is essential.
