Product details
Overview
TL061BCP from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for low-power, high-input-impedance 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+), 1 MHz unity-gain bandwidth, and 1012 Ω input resistance - enabling precision DC-coupled amplification in battery-powered sensors and audio front-ends.
For engineers reviewing the TL061BCP datasheet, TL061BCP pinout, TL061BCP application, or TL061BCP equivalent, key selection criteria include its JFET-input stage for ultra-low bias current (≤200 pA at 25°C), rail-to-rail-compatible common-mode range, internal frequency compensation for stable unity-gain operation, and SOIC-8 packaging suitable for space-constrained PCB layouts.
Technical Context
The TL061BCP implements a fully differential JFET-input stage followed by a high-gain CMOS transconductance amplifier and class-AB output stage, supporting stable operation with capacitive loads up to 100 pF. Its internal frequency compensation ensures unconditional stability in standard inverting and non-inverting configurations without external components.
Designed as a low-power variant of the TL07x/TL08x families, the TL061BCP maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew rate) while reducing quiescent current by ~50%. It operates across 0°C to 70°C (Commercial grade) with ±5 V to ±15 V dual-supply capability and features latch-up-free silicon construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA typical per amplifier - enables multi-stage analog signal chains in power-constrained applications like portable instrumentation. |
| Input Bias Current | ≤200 pA at 25°C - preserves signal integrity in high-impedance sensor interfaces (e.g., piezoelectric, pH electrodes). |
| Slew Rate | 3.5 V/µs typical - supports faithful reproduction of audio-band signals (≤100 kHz full-power) without distortion. |
| Unity-Gain Bandwidth | 1 MHz - allows stable closed-loop gain ≥1 with predictable phase margin in filter and buffer designs. |
| Common-Mode Range | Includes VCC+ (–12 V to +15 V with ±15 V supplies) - simplifies single-supply biasing and eliminates level-shifting in rail-referenced circuits. |
| Input Resistance | 1012 Ω - minimizes loading error on high-Z sources such as photodiode transimpedance nodes or passive RC filters. |
| ESD Rating | 1.5 kV CDM - provides robust handling during automated assembly and field deployment in unshielded environments. |
Pinout & Package
TL061BCP is supplied 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 lead pitch. The package is RoHS-compliant and rated for surface-mount reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected - must remain floating; no PCB trace or via required. |
| 2 | Inverting Input (IN–) | Differential input node for feedback networks; high-impedance JFET gate structure minimizes current injection error. |
| 3 | Non-Inverting Input (IN+) | Reference input node; common-mode voltage range extends to VCC+, enabling direct connection to positive supply rails. |
| 4 | Negative Supply (VCC–) | Ground reference for dual-supply operation; supports –5 V to –15 V range with thermal derating above 70°C ambient. |
| 5 | No Connect (NC) | Internally unconnected - must remain floating; no pull-up/down or bypassing permitted. |
| 6 | Output (OUT) | Class-AB buffered output capable of ±10 V swing into 10 kΩ load; short-circuit protected per absolute maximum ratings. |
| 7 | Positive Supply (VCC+) | Power rail for dual-supply operation; supports +5 V to +15 V range; decoupling capacitor (0.1 µF ceramic) required within 5 mm. |
| 8 | No Connect (NC) | Internally unconnected - must remain floating; no thermal pad or heatsinking function. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Enables ≤200 pA input bias current at 25°C - critical for maintaining accuracy in high-impedance transducer interfaces. |
| Internal frequency compensation | Guarantees stable unity-gain operation without external compensation components - reduces BOM count and layout complexity. |
| Output short-circuit protection | Allows indefinite output shorting to either supply rail without damage - improves system reliability during fault conditions. |
| Latch-up-free process | Prevents destructive parasitic thyristor conduction under overvoltage or ESD stress - ensures long-term functional safety. |
| Wide common-mode range | Supports input voltages up to VCC+ - eliminates need for external level shifters in single-ended sensor signal conditioning. |

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), 10× faster slew rate (13 V/µs), lower input noise (18 nV/√Hz) | Better suited for wideband audio or fast-settling data acquisition where power is not constrained | Select TL071CP only when higher speed and lower noise justify 12.5× higher quiescent power consumption. |
| LM358DR | Bipolar input (vs JFET), higher input bias current (45 nA), rail-to-rail output (vs limited swing), lower cost | Ideal for general-purpose DC amplification where ultra-low input current is unnecessary | Choose LM358DR for cost-driven, low-speed applications with <100 kΩ source impedance and single-supply operation. |
Compared with TL071CP and LM358DR, the TL061BCP uniquely balances ultra-low power (200 µA), JFET-input precision (≤200 pA bias), and industry-standard SOIC-8 compatibility - making it optimal for battery-powered sensor nodes and legacy-design drop-in replacements requiring minimal layout change.

FAQ
What is the maximum operating temperature range for TL061BCP?
The TL061BCP is specified for commercial-grade operation from 0°C to 70°C ambient temperature. Its absolute maximum junction temperature is 150°C, and thermal derating begins above 70°C based on package-specific RθJA (97°C/W for SOIC-8). For extended temperature applications, consider the TL061I (–40°C to +85°C) or TL061M (–55°C to +125°C) variants instead of TL061BCP.
Does TL061BCP support single-supply operation?
Yes, TL061BCP supports single-supply operation with appropriate input biasing. Its common-mode input voltage range extends to VCC+, allowing the non-inverting input to be tied directly to a mid-rail reference (e.g., VCC/2) while accepting signals referenced to ground. Output swing remains limited to approximately ±10 V under ±15 V supplies, so single-supply designs require careful headroom planning.
Can TL061BCP drive capacitive loads reliably?
TL061BCP is internally compensated for unity-gain stability and can safely drive capacitive loads up to 100 pF without oscillation, as verified in Figure 6-13 of the datasheet. For loads exceeding 100 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to maintain phase margin and prevent peaking or ringing in pulse response.
How does TL061BCP differ from TL061CP?
TL061BCP and TL061CP share identical electrical specifications and SOIC-8 packaging, but differ in input offset voltage grading: TL061BCP guarantees ≤3 mV max at 25°C (vs ≤6 mV for TL061CP), making it suitable for higher-precision DC-coupled applications. Both parts use the same die and process - the 'B' suffix denotes tighter initial offset binning without changes to pinout, footprint, or thermal behavior.
Is TL061BCP pin-compatible with other TL06x family members?
No - TL061BCP is a single-channel device in 8-pin SOIC, while TL062BCP (dual) and TL064BCP (quad) use different pinouts and package counts (8-pin and 14-pin respectively). Direct substitution between channel counts is not possible. However, TL061BCP is pin-compatible with TL071CP, TL081CP, and LM324N (single section) in SOIC-8, subject to verification of supply current, noise, and slew rate requirements.
