Product details
Overview
TL061ACD 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 TL061ACD datasheet, TL061ACD pinout, TL061ACD application, or TL061ACD equivalent, key selection criteria include its JFET-input stage for ultra-low bias current (30 pA typ.), internal frequency compensation for unity-gain stability, output short-circuit protection, and SOIC-8 packaging suitable for space-constrained PCB layouts.
Technical Context
The TL061ACD implements a JFET-input differential pair with high-impedance gate-driven stages, enabling femtoampere-level input bias currents and wide common-mode voltage range extending to VCC+. Its fully compensated internal architecture ensures stable operation at unity gain without external components.
It operates from dual supplies of ±5 V to ±15 V, supports rail-to-rail output swing within ±10 V (at 10 kΩ load), and maintains 80 dB CMRR and 80 dB PSRR across 0°C to 70°C ambient temperature - meeting requirements for industrial-grade signal amplification where power efficiency 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 like portable tablets and smart appliances. |
| Slew Rate | 3.5 V/µs typical - supports faithful reproduction of audio-band signals and fast transient response in active filters and sensor buffers. |
| Input Resistance | 1012 Ω - preserves signal integrity when interfacing high-impedance sources such as piezoelectric sensors or pH electrodes. |
| Input Offset Voltage | 3 mV max at 25°C - ensures baseline accuracy in DC-coupled instrumentation without requiring frequent calibration. |
| Common-Mode Range | –12 V to +15 V (with ±15 V supplies) - allows direct connection to signals referenced to positive rails, simplifying level-shifting circuits. |
| Unity-Gain Bandwidth | 1 MHz - provides sufficient small-signal bandwidth for anti-aliasing filters, transimpedance amplifiers, and general-purpose gain stages. |
| ESD Rating | 2000 V HBM - enhances robustness during handling and assembly in standard manufacturing environments. |
Pinout & Package
TL061ACD is housed in an 8-pin SOIC (Small Outline Integrated Circuit) 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 accepting feedback or signal inversion; high-impedance JFET gate structure minimizes loading. |
| 3 | Non-Inverting Input (IN+) | Reference input for follower or non-inverting configurations; supports common-mode voltages up to VCC+. |
| 4 | Negative Supply (VCC–) | Ground or negative rail connection; establishes lower operating boundary for internal biasing and output swing. |
| 5 | No Connect (NC) | Internally unconnected; left unpopulated on PCB to avoid parasitic coupling. |
| 6 | Output (OUT) | Amplified single-ended output capable of ±10 V swing into 10 kΩ; includes short-circuit protection limiting fault current. |
| 7 | Positive Supply (VCC+) | Primary power rail; supplies internal current mirrors and output stage; accepts up to +18 V absolute maximum. |
| 8 | No Connect (NC) | Internally unconnected; electrically isolated to prevent unintended signal paths or noise injection. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Delivers 30 pA typical input bias current - essential for integrating photodiode or capacitive sensor outputs without drift. |
| Internal frequency compensation | Guarantees unity-gain stability without external compensation components - reduces BOM count and layout complexity. |
| Output short-circuit protection | Limits output current during fault conditions - prevents device destruction and system-level damage in production environments. |
| Latch-up-free operation | Ensures reliable recovery after overvoltage or ESD events - eliminates need for system reset logic in safety-critical monitoring paths. |
| High input impedance (1012 Ω) | Maintains signal fidelity across decades of source impedance - critical for electrochemical and biomedical sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CD | Higher slew rate (13 V/µs), higher supply current (2.5 mA), same SOIC-8 package. | Better suited for wideband audio or fast-settling data acquisition where power budget allows. | Choose TL071CD only if bandwidth >1 MHz and slew rate >10 V/µs are required; TL061ACD remains optimal for sub-1 MHz, ultra-low-power use cases. |
| LM358DR | Bipolar input (20 nA bias current), lower input impedance (2 MΩ), rail-to-rail output not supported. | Acceptable for low-cost, non-critical DC amplification but unsuitable for high-Z sensor buffering. | Select LM358DR only for cost-driven, low-performance applications; TL061ACD is mandatory when input bias current <100 pA or input Z >1 GΩ is required. |
Compared with TL071CD and LM358DR, TL061ACD uniquely balances JFET-input precision (pA-level bias current, TΩ input Z) with micropower operation (200 µA), making it irreplaceable in battery-powered sensor nodes and portable instrumentation where both accuracy and energy efficiency are non-negotiable.

FAQ
What is the maximum supply voltage rating for TL061ACD?
The TL061ACD has an absolute maximum supply voltage rating of ±18 V across VCC+ and VCC–. Operation beyond this limit risks permanent damage. For reliable long-term use, TI specifies recommended operating conditions of ±5 V to ±15 V - ensuring optimal performance while preserving device lifetime and thermal margin in the TL061ACD.
Does TL061ACD support rail-to-rail input or output operation?
The TL061ACD does not support rail-to-rail input or output. Its common-mode input range extends to VCC+ but stops 4 V short of VCC– (i.e., VCC– + 4 V minimum), and its output swing is limited to ±10 V into 10 kΩ under ±15 V supplies. This behavior is inherent to its JFET-input, bipolar-output architecture - confirmed in Section 6.3 and Figure 6-1 of the TL061ACD datasheet.
Can TL061ACD be used in single-supply configurations?
Yes, TL061ACD can operate from a single supply by referencing its VCC– pin to ground and applying a mid-rail bias (e.g., VCC+/2) to the non-inverting input. Its common-mode range includes VCC+, allowing IN+ to accept signals near the positive rail - a key advantage over many bipolar op-amps. Designers must ensure input and output voltage ranges stay within specified limits per Section 6.3 of the TL061ACD datasheet.
What is the input offset voltage specification for TL061ACD at full temperature range?
For the TL061ACD (C-grade), the input offset voltage is guaranteed to be ≤20 mV over the full operating temperature range of 0°C to 70°C. At 25°C, the typical value is 3 mV with a maximum of 6 mV. These values are explicitly listed in Table 6-7 (Electrical Characteristics for TL06xC and TL06xxC) of the official TL061ACD datasheet revision SLOS078N.
Is TL061ACD pin-compatible with other members of the TL06x family?
Yes, TL061ACD shares identical pinout and package dimensions with TL061, TL061A, and TL061B variants in SOIC-8, PDIP-8, and SO-8 packages - all defined in Figure 5-1 and Table 5-1 of the TL061ACD datasheet. However, it is not pin-compatible with TL062 or TL064 due to differing channel counts and pin assignments; substitution requires PCB redesign.
