Product details
Overview
TL061ACPSR 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 3.5 V/μs slew rate, 1 MHz unity-gain bandwidth, ±13.5 V maximum output swing (at ±15 V supply), and ultra-low 200 μA supply current per amplifier - enabling battery-powered and thermally constrained applications such as sensor front-ends and portable audio preamps.
For engineers reviewing the TL061ACPSR datasheet, TL061ACPSR pinout, TL061ACPSR application, or TL061ACPSR equivalent, key selection criteria include its JFET-input stage (10¹² Ω input resistance), rail-to-rail common-mode range (including VCC+), low 30 nV/√Hz input voltage noise at 1 kHz, and SOIC-8 package compatibility with legacy TL071/TL081 footprints.
Technical Context
The TL061ACPSR uses a JFET-input differential pair followed by a high-gain Darlington output stage, internally compensated for unity-gain stability. Its architecture supports wide common-mode input range (VCC– + 4 V to VCC+ – 4 V) and operates from ±5 V to ±15 V dual supplies.
It features built-in output short-circuit protection, latch-up-free operation, and integrated EMI/RF filtering. The device is characterized across 0°C to 70°C (Commercial grade), with guaranteed parameters including 15 mV max input offset voltage, 200 pA max input bias current at 25°C, and 86 dB min CMRR.
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 supply budgets. |
| Slew Rate | 3.5 V/µs typical - supports clean amplification of audio-band signals up to ~100 kHz without distortion. |
| Unity-Gain Bandwidth | 1 MHz - allows stable closed-loop gain configurations down to G = 1 with phase margin >60°. |
| Input Offset Voltage | 6 mV max (TL061AC variant) - reduces DC error in precision transducer interfaces and active filters. |
| Input Resistance | 10¹² Ω - minimizes loading on high-impedance sources like piezoelectric sensors or photodiode TIA feedback networks. |
| Common-Mode Range | Includes VCC+ - permits direct sensing of signals referenced to positive rail (e.g., high-side current monitoring). |
| ESD Rating | 1.5 kV CDM - meets industrial handling requirements without additional board-level protection. |
Pinout & Package
TL061ACPSR is supplied in an 8-pin SOIC (PS) package measuring 6.20 mm × 7.80 mm, with standard 1.27 mm pitch and gull-wing leads. Thermal resistance RθJA is 95 °C/W, supporting operation up to +70°C ambient without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Unused internal node - must remain unconnected; no pull-up/down 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 buffer, non-inverting amplifier, or comparator reference inputs. |
| 4 | VCC– | Negative supply rail - must be decoupled locally with ≥0.1 µF ceramic capacitor to ground. |
| 5 | No Connect (NC) | Unused internal node - must remain unconnected; no routing or stubs allowed. |
| 6 | Output (OUT) | Amplified single-ended output - capable of ±10 V swing into 10 kΩ load at full temperature range. |
| 7 | VCC+ | Positive supply rail - must be decoupled locally with ≥0.1 µF ceramic capacitor to ground. |
| 8 | No Connect (NC) | Unused internal node - must remain unconnected; avoids parasitic coupling paths. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | 10¹² Ω input resistance and sub-nA input bias current enable accurate measurement of microamp-level sensor currents. |
| Internal frequency compensation | Guarantees stable unity-gain operation without external compensation components - simplifies PCB layout. |
| Output short-circuit protection | Allows indefinite output shorting to either rail or ground without damage - improves field reliability in motor-drive interface circuits. |
| Rail-inclusive common-mode range | Accepts input voltages up to VCC+, eliminating need for level-shifting in high-side sensing applications. |
| Low 30 nV/√Hz input voltage noise | Preserves signal integrity in low-level audio and instrumentation amplifiers where noise floor dominates SNR. |

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 2.5 mA supply current; 13 V/μs slew rate; tighter 10 mV max VIO (C-grade) | Better AC performance but 12.5× higher power - unsuitable for battery operation | Choose TL071CP only when bandwidth >3 MHz or lower noise (18 nV/√Hz) is mandatory. |
| LM358DR | Bipolar input (30 nA IIB); 0.6 V/μs slew rate; rail-to-rail output only; no VCC+ input capability | Lower cost but cannot handle high-impedance sources or high-side sensing | Choose LM358DR only for low-speed, low-precision, single-supply applications where input impedance >1 MΩ is not required. |
Compared with TL071CP and LM358DR, TL061ACPSR uniquely balances ultra-low power (200 µA), JFET-input integrity (10¹² Ω), and rail-inclusive common-mode range - making it the optimal choice for portable, high-impedance, and thermally constrained analog signal paths.

FAQ
What is the maximum operating temperature range for TL061ACPSR?
The TL061ACPSR is specified for commercial-grade operation from 0°C to +70°C ambient temperature. Its electrical characteristics - including input offset voltage (6 mV max), supply current (200 µA typ), and common-mode range - are guaranteed across this full range. Derating is recommended above +70°C; for extended temperature operation, consider TL061I (–40°C to +85°C) or TL061M (–55°C to +125°C) variants.
Does TL061ACPSR require external compensation capacitors?
No, TL061ACPSR includes internal frequency compensation optimized for unity-gain stability. It drives capacitive loads up to 100 pF without oscillation and supports closed-loop gains ≥1 without external components. For heavier capacitive loads (>100 pF), a small series resistor (10–50 Ω) between output and load is recommended to maintain phase margin.
Can TL061ACPSR operate from a single 5-V supply?
Yes, TL061ACPSR supports single-supply operation with VCC+ = 5 V and VCC– = 0 V. However, its common-mode input range extends only to VCC– + 4 V and VCC+ – 4 V, limiting usable input range to 1 V–4 V. Output swing is similarly restricted to ~1.5 V–3.5 V. For true rail-to-rail input/output, consider dedicated single-supply op amps like TLV2461.
What is the purpose of the NC pins on TL061ACPSR?
Pins 1, 5, and 8 on TL061ACPSR are No Connect (NC) terminals - internally unconnected silicon nodes. They must remain unconnected on PCBs: no traces, vias, or solder mask openings. Routing to these pins may introduce parasitic capacitance or coupling, degrading noise performance or stability. TI's SOIC-8 pinout diagram explicitly confirms their NC status.
How does TL061ACPSR compare to TL061CP in terms of input offset voltage?
TL061ACPSR has a tighter input offset voltage specification: 6 mV maximum (vs. 15 mV for TL061CP) at 25°C. This A-grade binning results from enhanced laser trimming during production, directly reducing DC error in precision gain stages and active filter designs. Both share identical pinout, package, and thermal characteristics - TL061ACPSR is a drop-in upgrade where lower initial offset is critical.
