Product details
Overview
TL061ACPSRG4 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 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 tablets and white goods.
For engineers reviewing the TL061ACPSRG4 datasheet, TL061ACPSRG4 pinout, TL061ACPSRG4 application, or TL061ACPSRG4 equivalent, this page provides verified electrical parameters, SOIC-8 package details, JFET-input stage advantages, and real-world implementation guidance for low-noise, low-quiescent-current designs.
Technical Context
The TL061ACPSRG4 implements a JFET-input differential pair with internal frequency compensation, delivering stable unity-gain operation without external components. Its high input impedance and low input bias current (30 pA typ. at 25°C) minimize loading on high-Z sources like piezoelectric sensors or photodiode transimpedance nodes.
It operates from dual supplies of ±5 V to ±15 V, supports rail-to-rail common-mode input (VCC– + 4 V to VCC+ – 4 V), and features output short-circuit protection. The device meets 1.5 kV HBM ESD rating and includes integrated EMI/RF filters for robustness in electrically noisy environments.
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 |
| Slew Rate | 3.5 V/µs typical - supports audio-band signal amplification with minimal distortion |
| Input Resistance | 1012 Ω - preserves signal integrity when interfacing with megohm-level sensor impedances |
| Input Offset Voltage | 3 mV max at 25°C - suitable for DC-coupled gain stages requiring <1% error at 100× gain |
| Unity-Gain Bandwidth | 1 MHz - enables stable closed-loop operation up to ~100 kHz with moderate capacitive loads |
| Common-Mode Range | VCC– + 4 V to VCC+ – 4 V - allows direct sensing of signals near supply rails in single-supply configurations |
| ESD Rating | 1.5 kV HBM - provides baseline handling robustness during PCB assembly and field operation |
Pinout & Package
TL061ACPSRG4 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 in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Unused internal node - must remain unconnected to avoid parasitic coupling |
| 2 | Inverting Input (IN–) | Differential input terminal for feedback network connection in inverting configurations |
| 3 | Non-Inverting Input (IN+) | Differential input terminal for reference or sensor signal routing in non-inverting topologies |
| 4 | VCC– | Negative power supply rail - requires local 0.1 µF ceramic decoupling to ground |
| 5 | No Connect (NC) | Unused internal node - must remain unconnected to prevent noise injection |
| 6 | Output (OUT) | Amplified single-ended output - capable of driving ≥10 kΩ loads with ±10 V swing |
| 7 | VCC+ | Positive power supply rail - requires local 0.1 µF ceramic decoupling to ground |
| 8 | No Connect (NC) | Unused internal node - must remain unconnected to maintain specified CMRR and PSRR |
Key Features

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), higher supply current (2.8 mA), no integrated EMI filtering | Better suited for wideband audio or fast-settling data acquisition where speed outweighs power constraints | Select TL071CP only if bandwidth >1 MHz and supply current >2 mA are acceptable |
| LM358DR | Bipolar input (30 nA bias current), lower input impedance (200 kΩ), rail-to-rail output (not input) | Lower cost for non-critical DC amplification where sensor impedance <100 kΩ and rail-sensing not required | Choose LM358DR for cost-driven, low-speed applications with modest accuracy requirements |
Compared with TL071CP and LM358DR, TL061ACPSRG4 uniquely balances ultra-low power (200 µA), JFET-input impedance (1012 Ω), and integrated EMI filtering - making it optimal for battery-powered, high-Z sensor interfaces where both precision and efficiency are mandatory.

FAQ
What is the maximum supply voltage for TL061ACPSRG4?
The TL061ACPSRG4 supports dual-supply operation from ±5 V to ±15 V, with absolute maximum ratings of ±18 V. Exceeding ±15 V reduces reliability and may trigger thermal shutdown under load. For TL061ACPSRG4, recommended operation at ±12 V balances headroom and power dissipation in most applications.
Does TL061ACPSRG4 require external compensation capacitors?
No, TL061ACPSRG4 includes internal frequency compensation and is stable in unity-gain and inverting configurations without external components. This eliminates layout complexity and component count in TL061ACPSRG4-based designs, unlike some decompensated op-amps that mandate external capacitors for stability.
Can TL061ACPSRG4 drive capacitive loads directly?
TL061ACPSRG4 can safely drive ≤100 pF capacitive loads without oscillation. For larger loads (e.g., long cables or ADC input capacitance), a series isolation resistor (20–100 Ω) between TL061ACPSRG4 output and the load is recommended to maintain phase margin and prevent peaking.
What is the input offset voltage drift over temperature for TL061ACPSRG4?
TL061ACPSRG4 has a guaranteed temperature coefficient of input offset voltage (αVIO) of 10 µV/°C across its full operating range. At 25°C, typical VIO is 1.5 mV; over 0°C to 70°C, total drift remains within ±0.7 mV - critical for DC-coupled TL061ACPSRG4 sensor amplifiers.
Is TL061ACPSRG4 pin-compatible with other TL06x variants?
Yes, TL061ACPSRG4 shares identical SOIC-8 pinout with all TL061x variants (e.g., TL061CP, TL061CDR), including TL061ACPSRG4. Pin compatibility extends to TL071 and TL081 families, enabling drop-in replacement where performance margins allow - though TL061ACPSRG4's lower power and JFET input differ functionally.
