Product details
Overview
TL061ACDE4 from Texas Instruments is a single-channel, low-power JFET-input operational amplifier optimized for cost-sensitive analog signal conditioning in industrial and consumer systems. It delivers 3.5 V/μs slew rate, 1 MHz unity-gain bandwidth, 200 μA typical supply current per amplifier, ±15 V max supply voltage, and 10¹² Ω input resistance - enabling precision DC-coupled amplification in battery-powered or thermally constrained designs such as sensor front-ends and portable audio.
For engineers reviewing the TL061ACDE4 datasheet, TL061ACDE4 pinout, TL061ACDE4 application, or TL061ACDE4 equivalent, key selection criteria include its JFET-input stage (enabling pA-level bias current), rail-to-rail common-mode input range extending to VCC+, output short-circuit protection, and SOIC-8 packaging suitable for high-density PCB layouts requiring low quiescent power.
Technical Context
The TL061ACDE4 implements a fully differential JFET-input stage followed by a high-voltage gain cell and Class-AB output stage, internally compensated for unity-gain stability. Its architecture supports operation from ±5 V to ±15 V supplies while maintaining low input offset voltage (max 6 mV at 25°C) and ultra-low input bias current (max 200 pA at 25°C).
Designed as a lower-power counterpart to the TL071 and TL081 families, it retains wide common-mode (±11 V) and differential input ranges, high CMRR (min 80 dB), and robust ESD tolerance (1.5 kV HBM), making it suitable for noisy environments without external filtering overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA typical per amplifier - enables multi-stage analog chains in <1 mA total system bias budgets. |
| Slew Rate | 3.5 V/µs typical - supports clean amplification of audio-band signals up to ~100 kHz at unity gain. |
| Unity-Gain Bandwidth | 1 MHz - ensures stable closed-loop operation with gain ≥1 and predictable phase margin. |
| Input Bias Current | 200 pA max at 25°C - minimizes voltage error across high-impedance source networks (e.g., piezoelectric sensors). |
| Common-Mode Input Range | Extends to VCC+ - allows direct interfacing with signals referenced to positive rail (e.g., single-supply sensor outputs). |
| ESD Rating | 1.5 kV HBM - reduces need for external protection in board-level ESD-prone applications like white goods controls. |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade embedded systems including tablets and personal electronics. |
Pinout & Package
TL061ACDE4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 6.00 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. The package supports automated assembly and provides thermal resistance RθJA = 97°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Unused internal node - must remain unconnected; no electrical function or routing required. |
| 2 | Inverting Input (IN–) | Differential input terminal; accepts feedback network connection for inverting configurations. |
| 3 | Non-Inverting Input (IN+) | Differential input terminal; used for positive signal injection and reference biasing. |
| 4 | VCC– | Negative supply rail connection; must be decoupled locally to minimize noise coupling. |
| 5 | No Connect (NC) | Unused internal node - must remain unconnected; no electrical function or routing required. |
| 6 | Output (OUT) | Amplified single-ended output; capable of ±10 V swing into 10 kΩ load at ±15 V supply. |
| 7 | VCC+ | Positive supply rail connection; requires local 0.1 µF ceramic decoupling to ground. |
| 8 | No Connect (NC) | Unused internal node - must remain unconnected; no electrical function or routing required. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Enables 10¹² Ω input resistance and sub-nA input bias current - critical for high-Z sensor interfaces. |
| Internal frequency compensation | Guarantees stability at unity gain without external components - simplifies design and reduces BOM count. |
| Output short-circuit protection | Prevents device damage during accidental load faults - eliminates need for external current-limiting resistors. |
| Rail-to-rail common-mode input | Accepts inputs up to VCC+ - supports direct connection to microcontroller DAC outputs or other rail-referenced sources. |
| Latch-up-free operation | Ensures robustness against input overvoltage transients beyond supply rails - improves field reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CDR | Higher supply current (2.8 mA vs 0.2 mA); 13 V/μs slew rate; tighter offset (10 mV max vs 6 mV). | Better AC performance but unsuitable for ultra-low-power systems; requires higher thermal budget. | Select TL071CDR only when bandwidth >3 MHz or slew rate >10 V/μs is required - not a drop-in replacement. |
| LM358DR | Bipolar input (65 nA bias current vs 200 pA); rail-to-rail output only; no VCC+-inclusive input range. | Lower cost and wider temp range (−40°C to 125°C), but incompatible with high-Z sources or rail-referenced inputs. | Choose LM358DR for general-purpose, low-cost dual-op-amp needs where input impedance >1 GΩ is not required. |
Compared with TL061ACDE4, TL071CDR trades 14× higher quiescent power for 3.7× faster slew rate and improved noise performance, while LM358DR sacrifices JFET-level input impedance and common-mode range for broader temperature support and lower unit cost - neither offers pin compatibility or identical electrical behavior.

FAQ
What is the maximum supply voltage rating for TL061ACDE4?
The TL061ACDE4 has an absolute maximum supply voltage rating of ±18 V across VCC+ and VCC– terminals. However, the recommended operating range is ±5 V to ±15 V per the datasheet's Recommended Operating Conditions table. Exceeding ±15 V may degrade long-term reliability or trigger internal protection mechanisms, and operation above ±18 V risks permanent damage. Always observe derating guidelines for thermal management when operating near limits.
Does TL061ACDE4 support rail-to-rail input or output?
TL061ACDE4 supports rail-to-rail common-mode input voltage - its input range extends to VCC+, enabling direct connection to signals referenced to the positive supply rail. However, its output swing is limited to ±10 V into 10 kΩ at ±15 V supply (i.e., not rail-to-rail output). Output does not reach within 2 V of either rail under typical loads, so it cannot drive logic-level signals directly without additional level-shifting circuitry.
Can TL061ACDE4 be used in single-supply configurations?
Yes, TL061ACDE4 can operate from a single supply (e.g., +15 V and ground) by biasing the IN+ pin to mid-rail using a resistor divider and capacitor. Its common-mode input range includes VCC+, allowing the non-inverting input to be set at VCC/2, and its output swings down to within ~2 V of VCC– (ground). This configuration is widely used in portable audio and sensor signal chains where dual supplies are impractical.
What is the input offset voltage specification for TL061ACDE4?
The TL061ACDE4 has a maximum input offset voltage of 6 mV at 25°C and full temperature range (0°C to 70°C), with a typical value of 3 mV. This parameter is specified for the 'AC' grade variant per Table 6.7 of the datasheet. Offset voltage drift is rated at 10 µV/°C maximum, ensuring predictable DC error accumulation across the operating temperature span - critical for precision DC amplification tasks.
Is TL061ACDE4 pin-compatible with other TL06x variants like TL062 or TL064?
No, TL061ACDE4 is not pin-compatible with TL062 or TL064. As a single-channel device in SOIC-8, it uses pins 1–8 with NC/IN–/IN+/VCC–/NC/OUT/VCC+/NC layout. TL062 (dual) and TL064 (quad) occupy different pinouts and package counts (8-pin and 14-pin respectively) to accommodate multiple amplifiers. Interchanging them requires PCB redesign - only same-channel-count variants (e.g., TL061ACP vs TL061ACDE4) share pinout compatibility.
