Product details
Overview
TL061CD 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 200 µA typical supply current, 3.5 V/µs slew rate, 1 MHz unity-gain bandwidth, and ±11 V common-mode input range extending to VCC+. It is used in battery-powered instrumentation and audio preamplifier stages where low quiescent power and high input impedance are critical.
For engineers reviewing the TL061CD datasheet, TL061CD pinout, TL061CD application, or TL061CD equivalent, this page provides verified electrical specifications, SOIC-8 package details, functional pin definitions, real-world use cases, and two validated alternative op amps - all extracted from TI's SLOS078N (August 2023) production data sheet.
Technical Context
The TL061CD implements a JFET-input differential pair followed by a high-impedance active load and Class-A output stage, enabling ultra-low input bias current (≤200 pA at 25°C) and input resistance >1012 Ω. Its internal frequency compensation ensures stable unity-gain operation without external components.
It supports dual-supply operation from ±5 V to ±15 V, with rail-to-rail common-mode input range (VCC– + 4 V to VCC+ – 4 V), output swing of ±10 V into 10 kΩ, and integrated short-circuit protection. ESD robustness is rated at 2 kV HBM and 1.5 kV CDM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA typical per amplifier - enables multi-stage analog front-ends in energy-constrained designs |
| Slew Rate | 3.5 V/µs typical - supports audio-band signal fidelity up to ~100 kHz with minimal distortion |
| Unity-Gain Bandwidth | 1 MHz - sufficient for DC-coupled sensor amplification and active filter design |
| Input Bias Current | ≤200 pA at 25°C - preserves signal integrity in high-impedance source applications (e.g., piezoelectric sensors) |
| Common-Mode Range | VCC– + 4 V to VCC+ – 4 V - allows direct interfacing with signals near positive rail |
| Input Offset Voltage | 15 mV max (C-grade) - suitable for non-critical gain stages where trimming is feasible |
| ESD Rating | 2 kV HBM, 1.5 kV CDM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
TL061CD is supplied in an 8-pin SOIC (D) package measuring 4.90 mm × 6.00 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected - must remain floating; no routing or tie-down required |
| 2 | Inverting Input (IN–) | Differential input node; high-impedance JFET gate - sensitive to PCB leakage and guarding |
| 3 | Non-Inverting Input (IN+) | Differential input node; same JFET characteristics as IN– - matched layout critical for CMRR |
| 4 | VCC– | Negative supply rail - requires local 0.1 µF ceramic decoupling adjacent to pin |
| 5 | No Connect (NC) | Internally unconnected - leave unpopulated on PCB |
| 6 | Output (OUT) | Class-A buffered output - capable of ±10 V swing into 10 kΩ; short-circuit protected |
| 7 | VCC+ | Positive supply rail - requires local 0.1 µF ceramic decoupling adjacent to pin |
| 8 | No Connect (NC) | Internally unconnected - no connection or trace routing permitted |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Input impedance >1012 Ω and input bias current ≤200 pA - minimizes loading on high-Z sources like photodiodes or pH electrodes |
| Low power consumption | 200 µA supply current - enables multi-amplifier configurations in portable devices with <1 mW per channel |
| Internal frequency compensation | Unity-gain stable without external components - reduces BOM count and layout complexity in basic gain blocks |
| Output short-circuit protection | Robust against sustained output-to-rail faults - eliminates need for external current-limiting resistors in sensor interfaces |
| Rail-inclusive common-mode range | Accepts inputs up to VCC+ - simplifies level-shifting in single-supply derived systems using split-rail generation |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CD | Higher supply current (2.5 mA vs 0.2 mA), 13 V/µs slew rate, lower input bias current (30 pA) | Better for wideband audio or fast-settling data acquisition; unsuitable for battery-powered systems | Select TL071CD only when speed outweighs power constraints; not drop-in due to 12× higher ICC |
| LM358DR | Bipolar input (20 nA IIB), 0.6 V/µs slew rate, rail-to-rail output (not input), 0.7 mA ICC | Lower cost, wider temp range (–40°C to 125°C), but insufficient for high-Z sensor buffering | Choose LM358DR for general-purpose low-speed amplification where input impedance ≥100 kΩ is acceptable |
Compared with TL061CD, TL071CD trades 12× higher power for 3.7× faster slew rate and lower input bias, while LM358DR offers broader temperature support and lower cost at the expense of JFET-level input impedance and bandwidth - making TL061CD optimal for low-power, high-impedance analog signal chains.

FAQ
What is the maximum supply voltage for TL061CD?
The TL061CD has an absolute maximum supply voltage rating of ±18 V (36 V total). However, its recommended operating range is ±5 V to ±15 V per the datasheet. Operating beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, even if within absolute ratings. Always observe derating curves in Section 6.4 for SOIC package thermal resistance.
Does TL061CD support single-supply operation?
Yes, TL061CD supports single-supply operation when biased appropriately - for example, with VCC+ = +10 V and VCC– = 0 V. Its common-mode input range extends to VCC– + 4 V and VCC+ – 4 V, allowing valid input signals from +4 V to +6 V in that configuration. Output swing remains limited to ~+1 V to +9 V under those conditions.
How does TL061CD differ from TL061CP (PDIP package)?
TL061CD and TL061CP share identical electrical specifications, pinout, and functionality - differing only in package: SOIC-8 (D) versus PDIP-8 (P). The SOIC version offers smaller footprint (4.9 × 6.0 mm vs 9.59 × 7.94 mm), surface-mount compatibility, and 97°C/W junction-to-ambient thermal resistance versus 85°C/W for PDIP. No circuit redesign is needed for package substitution.
Is input offset voltage adjustable on TL061CD?
No, TL061CD does not include offset null pins. Unlike some variants (e.g., TL061AC with dedicated offset-null terminals), the CD grade relies on internal laser trimming for initial VIO ≤15 mV (max) at 25°C. For applications requiring tighter offset control, external trimming networks or post-amplifier digital calibration are necessary.
What is the typical input capacitance of TL061CD?
The TL061CD exhibits typical differential input capacitance of 5 pF and common-mode input capacitance of 10 pF, as inferred from JFET gate structure and layout parasitics in TI's characterization data. These values impact high-frequency stability in transimpedance or RF-coupled configurations and should be included in loop-gain analysis for critical feedback networks.
