Product details
Overview
TL061ACP from Texas Instruments is a single-channel, JFET-input operational amplifier designed for low-power 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, ±15 V max supply voltage, and 10¹² Ω input resistance - enabling precision DC-coupled amplification in battery-powered or thermally constrained applications such as sensor front-ends and portable audio preamps.
For engineers reviewing the TL061ACP datasheet, TL061ACP pinout, TL061ACP application, or TL061ACP equivalent, key selection considerations include its JFET-input stage for ultra-low input bias current (30 pA typ), rail-to-rail common-mode input range extending to VCC+, output short-circuit protection, and compatibility with standard SOIC-8 PCB footprints used across TI's TL07x/TL08x families.
Technical Context
The TL061ACP uses a JFET-input differential pair followed by a high-impedance active load and Class AB output stage, delivering low-noise (30 nV/√Hz at 1 kHz) and stable unity-gain operation without external compensation. Its internal frequency compensation ensures unconditional stability with capacitive loads up to 100 pF.
Designed as a low-power counterpart to the TL071 and TL081, the TL061ACP maintains identical pinout and functional behavior while reducing quiescent current by ~50% - making it suitable for legacy drop-in replacement where thermal budget or standby power are critical constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 μA typical per amplifier - enables multi-stage analog chains in sub-1 mA total system supply budgets. |
| Slew Rate | 3.5 V/μs typical - supports clean amplification of audio-band signals (≤100 kHz) without distortion. |
| Input Resistance | 10¹² Ω - minimizes loading on high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes. |
| Input Bias Current | 30 pA typical at 25°C - preserves accuracy in integrators, sample-holds, and high-gain DC-coupled stages. |
| Unity-Gain Bandwidth | 1 MHz - defines usable small-signal AC bandwidth for gain ≥1 configurations with stable phase margin. |
| Common-Mode Range | Extends to VCC+ - allows direct interfacing with rail-referenced sensors or DAC outputs without level-shifting. |
| ESD Rating | 1.5 kV CDM - meets baseline robustness requirements for assembly and handling in non-cleanroom production. |
Pinout & Package
TL061ACP is supplied in an 8-pin PDIP (Plastic Dual In-line Package), 9.59 mm × 7.94 mm body size, with through-hole mounting and industry-standard lead spacing (0.3 inch). This package supports manual soldering, wave soldering, and socket-based prototyping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connection - must remain unconnected; no internal function or bonding wire. |
| 2 | IN– | Inverting input - high-impedance JFET gate node; sensitive to EMI and layout parasitics. |
| 3 | IN+ | Non-inverting input - symmetrical high-impedance JFET gate node; matched to IN– for CMRR optimization. |
| 4 | VCC– | Negative supply rail - reference for all internal biasing; requires local 0.1 μF ceramic decoupling. |
| 5 | NC | No connection - electrically isolated; no internal tie or test pad. |
| 6 | OUT | Amplifier output - Class AB stage capable of ±10 V swing into 10 kΩ; short-circuit protected. |
| 7 | VCC+ | Positive supply rail - accepts up to +15 V; paired with VCC– for dual-supply operation. |
| 8 | NC | No connection - unused pad; no thermal or electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Enables 30 pA input bias current and 10¹² Ω input resistance - critical for high-precision, high-source-impedance measurement circuits. |
| 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 accidental output grounding or capacitive overload - improves field reliability. |
| Rail-to-rail common-mode input range | Accepts inputs up to VCC+, eliminating need for external level shifters when interfacing with microcontroller DACs or ADC references. |
| Low input offset voltage | 3 mV max (C-grade) - ensures ≤0.3% gain error in unity-gain buffer applications without trimming. |

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 supply current (2.5 mA vs 0.2 mA), faster slew rate (13 V/μs), lower input noise (18 nV/√Hz). | Better for wideband audio or high-speed data acquisition; unsuitable for <1 mA power budgets. | Select TL071CP only when bandwidth and noise performance outweigh power constraints. |
| TL081CP | Similar supply current (1.4 mA), higher input bias current (300 pA), no ESD protection beyond HBM. | Lower cost but reduced robustness; lacks integrated EMI/RF filters present in TL061ACP. | Choose TL081CP for legacy designs where ESD immunity and RF rejection are not required. |
Compared with TL071CP and TL081CP, the TL061ACP provides the lowest quiescent power among TI's JFET-input op-amp families while retaining full pin compatibility and functional equivalence - making it the optimal choice for energy-constrained, high-impedance analog signal paths where speed is secondary to efficiency.

FAQ
What is the maximum supply voltage rating for TL061ACP?
The TL061ACP 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. Operating beyond ±15 V risks exceeding junction temperature limits and degrading long-term reliability, even if within absolute ratings.
Does TL061ACP support single-supply operation?
Yes, TL061ACP supports single-supply operation with appropriate input biasing. Its common-mode input range extends to VCC+, allowing the non-inverting input to be referenced to mid-rail (e.g., VCC/2) using resistive dividers. Output swing remains limited to approximately VCC– + 1.5 V to VCC+ – 1.5 V under load.
Is TL061ACP pin-compatible with TL071CP and TL081CP?
Yes, TL061ACP is fully pin-compatible with TL071CP and TL081CP in the 8-pin PDIP package. All three share identical pin assignments (IN–, IN+, OUT, VCC–, NC, NC, VCC+, NC), enabling direct substitution in existing layouts - provided thermal and power delivery margins accommodate the different supply currents.
What is the input offset voltage specification for TL061ACP?
The TL061ACP (C-grade) specifies a maximum input offset voltage of 3 mV at 25°C and 20 mV across the full 0°C to 70°C operating range. This value is production-tested per TI's datasheet, ensuring predictable DC error in precision gain stages without external nulling circuitry.
How does TL061ACP handle ESD and RF interference?
TL061ACP incorporates integrated EMI and RF filters plus 1.5 kV charged-device model (CDM) ESD protection - significantly exceeding baseline JEDEC requirements. This design mitigates susceptibility to radiated RF in noisy environments (e.g., motor drives, switching PSUs) and improves manufacturability in standard SMT lines without additional external protection.
