Product details
Overview
TL061ACPSRE4 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 sensor front-ends and audio preamplifiers where low power and high input impedance are critical.
For engineers reviewing the TL061ACPSRE4 datasheet, TL061ACPSRE4 pinout, TL061ACPSRE4 application, or TL061ACPSRE4 equivalent, this page provides verified electrical specifications, SOIC-8 package details, real-world use cases, and two validated alternative op amps with documented functional and parametric differences.
Technical Context
The TL061ACPSRE4 implements a JFET-input differential pair with internal frequency compensation, enabling stable unity-gain operation without external components. Its high input impedance (10¹² Ω) and low input bias current (30 pA typ at 25°C) minimize loading on high-impedance sources like piezoelectric sensors or photodiode transimpedance stages.
It operates from dual supplies of ±5 V to ±15 V, supports rail-to-rail output swing within ±10 V under 10 kΩ load, and features output short-circuit protection. The device meets 1.5 kV HBM ESD rating and includes integrated EMI/RF filtering for robustness in electrically noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA typical per amplifier - enables battery-powered or energy-constrained designs with minimal quiescent power draw. |
| Slew Rate | 3.5 V/µs typical - supports faithful reproduction of audio-band signals and fast transient response in active filters. |
| Unity-Gain Bandwidth | 1 MHz - suitable for DC-coupled instrumentation, low-frequency active filters, and sensor amplification up to ~100 kHz. |
| Input Bias Current | 30 pA typical at 25°C - preserves accuracy in high-impedance transducer interfaces (e.g., pH electrodes, photodiodes). |
| Common-Mode Range | ±11 V (VCC– + 4 V to VCC+ – 4 V) - allows input signals to reach within 4 V of either supply rail, simplifying level-shifting design. |
| Input Offset Voltage | 3 mV max at 25°C - ensures <10 mV output error in unity-gain configurations without trimming, adequate for non-critical analog stages. |
| ESD Rating | 1.5 kV HBM - provides baseline handling robustness during PCB assembly and field service without requiring additional protection circuitry. |
Pinout & Package
TL061ACPSRE4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 6.00 mm, with standard 1.27 mm pitch and gull-wing leads compatible with automated SMT assembly.
| 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; connects to feedback network in inverting configurations or reference point in comparator setups. |
| 3 | Non-Inverting Input (IN+) | Differential input node; accepts signal source directly in non-inverting gain stages or sensor inputs. |
| 4 | Negative Supply (VCC–) | Ground or negative rail connection; must be decoupled locally with 0.1 µF ceramic capacitor. |
| 5 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding required. |
| 6 | Output (OUT) | Amplified single-ended output; capable of sourcing/sinking ≥10 mA into resistive loads. |
| 7 | Positive Supply (VCC+) | Positive rail connection; requires local 0.1 µF ceramic decoupling adjacent to pin. |
| 8 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | 10¹² Ω input resistance and ≤200 pA input bias current enable accurate amplification of microcurrent and high-Z voltage sources. |

IC Role / Device Role / Timing Role: High-impedance buffer driving multiplexer inputs or ADC reference buffers in multi-channel data acquisition systems. Use Value: ±11 V common-mode range accommodates sensor outputs referenced to system ground or floating supplies, reducing need for level-shifting. |
Use Scenario: Comparing regulated DC supply voltages (e.g., 5 V, 3.3 V) against precision references to trigger fault alerts in embedded power management. IC Role / Device Role / Timing Role: Comparator with hysteresis (via external feedback) detecting overvoltage/undervoltage thresholds.

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), lower input noise (18 nV/√Hz), but 2.8 mA supply current - 14× higher quiescent power than TL061ACPSRE4. | Better suited for wideband audio or high-speed active filters; unsuitable for battery-powered or thermally constrained designs. | Select TL071CP only when bandwidth/noise requirements exceed TL061ACPSRE4 capability and power budget permits. |
| RC4558P | Bipolar-input architecture: 500 nA input bias current, 0.5 V/μs slew rate, 3 mA supply current - significantly lower input impedance and speed. | Acceptable for low-frequency general-purpose amplification (e.g., simple comparators, basic gain stages) where JFET advantages are unnecessary. | Choose RC4558P for cost-driven, non-critical analog functions where input impedance >1 MΩ is not required and power efficiency is secondary. |
Compared with TL071CP and RC4558P, TL061ACPSRE4 uniquely balances ultra-low power (200 µA), JFET-input precision (30 pA bias, 10¹² Ω), and sufficient bandwidth (1 MHz) for sensor and audio front-ends - making it optimal where power, input impedance, and moderate speed intersect.

FAQ
What is the maximum supply voltage for TL061ACPSRE4?
The absolute maximum supply voltage for TL061ACPSRE4 is ±18 V, but the recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, especially at elevated ambient temperatures. Always observe derating curves in the datasheet's thermal information section.
Does TL061ACPSRE4 require external compensation capacitors?
No, TL061ACPSRE4 includes internal frequency compensation and is stable in unity-gain configurations without external components. This eliminates layout complexity and component count in standard inverting/non-inverting amplifier designs, though external compensation may be added for specialized high-speed or high-gain applications.
Can TL061ACPSRE4 drive a 2 kΩ load effectively?
Yes - TL061ACPSRE4 can drive a 2 kΩ load while maintaining ≥±10 V output swing at room temperature. However, output voltage compliance reduces under heavy loads due to internal output stage limitations; for full ±13.5 V swing, a minimum 10 kΩ load is recommended per the datasheet's VOM specification.
Is TL061ACPSRE4 pin-compatible with TL071 or TL081?
Yes - TL061ACPSRE4 uses the same SOIC-8 pinout as TL071CP and TL081CP, including identical IN+, IN–, OUT, VCC+, and VCC– assignments. However, direct substitution requires verification of slew rate, noise, and supply current requirements, as TL061ACPSRE4 trades performance for lower power consumption.
What is the input offset voltage drift over temperature for TL061ACPSRE4?
TL061ACPSRE4 has a guaranteed maximum input offset voltage drift of 10 µV/°C across its full operating range (0°C to 70°C). This low drift ensures predictable error accumulation in precision DC-coupled applications such as sensor amplifiers and reference buffers without frequent recalibration.
