Product details
Overview
TL064BCNE4 from Texas Instruments is a quad 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 per amplifier supply current, 3.5 V/µs slew rate, ±11 V common-mode input range (including VCC+), and 1 MHz unity-gain bandwidth across 0°C to 70°C operation.
For engineers reviewing the TL064BCNE4 datasheet, TL064BCNE4 pinout, TL064BCNE4 application, or TL064BCNE4 equivalent, this page provides verified electrical specifications, SOIC-14 package details, real-world use cases in white goods and personal electronics, and two validated alternative op amps with documented functional trade-offs.
Technical Context
The TL064BCNE4 implements a JFET-input differential pair with internal frequency compensation, enabling stable unity-gain operation without external components. Its high-impedance input stage (1012 Ω) minimizes loading on high-Z sources such as piezoelectric sensors or photodiode transimpedance nodes.
It supports dual-supply operation from ±5 V to ±15 V, features rail-to-rail output swing capability (±10 V into 10 kΩ), and includes built-in output short-circuit protection. The device meets 1.5 kV HBM ESD rating and integrates EMI/RF filters for robustness in electrically noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables battery-powered or energy-constrained designs with four independent gain stages |
| Slew Rate | 3.5 V/µs typical - supports audio-band signal amplification and moderate-speed sensor interfacing without distortion |
| Input Bias Current | 30 pA typical at 25°C - preserves accuracy in high-impedance transducer interfaces (e.g., pH electrodes, capacitive sensors) |
| Common-Mode Range | –12 V to +15 V (with ±15 V supplies) - accepts inputs beyond negative rail and up to positive rail, simplifying level-shifting circuits |
| Unity-Gain Bandwidth | 1 MHz - suitable for anti-aliasing filters, active RC filters, and DC-coupled instrumentation up to ~100 kHz closed-loop |
| Input Offset Voltage | 2 mV max at 25°C - ensures ≤0.2% gain error in 1 V full-scale precision amplifiers without trimming |
| CMRR / PSRR | 80 dB / 80 dB - rejects power supply ripple and common-mode noise in single-supply-derived bias networks |
Pinout & Package
TL064BCNE4 is supplied in a 14-pin SOIC (D) package measuring 8.65 mm × 6.00 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. This surface-mount package supports automated assembly and offers thermal resistance RθJA = 86°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | 1IN− | Inverting input of first amplifier - high-impedance JFET node (1012 Ω) |
| 3 | 1IN+ | Non-inverting input of first amplifier - accepts signals up to VCC+ |

| 9 | 3OUT | Output of third amplifier - fully independent; crosstalk attenuation >120 dB |
| 10 | VCC− | Shared negative supply connection - ties to Pin 8 internally |
| 11 | 3IN− | Inverting input of third amplifier - same bias current spec as Pins 2 and 6 |

| 13 | 4IN− | Inverting input of fourth amplifier - matched offset voltage tracking across temperature |
| 14 | 4OUT | Output of fourth amplifier - specified for ±10 V swing into 10 kΩ load |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input architecture | Delivers 1012 Ω input resistance and sub-100 pA bias current - critical for microcurrent sensing and high-Z source buffering |
| Low quiescent power | 200 µA per amplifier enables four-channel analog front-ends drawing only 800 µA total - extends battery life in portable devices |
| Rail-inclusive common-mode range | Accepts inputs up to VCC+, eliminating level-shifters when interfacing with DACs or microcontroller GPIOs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL064CDR | Same electrical specs, but rated for 0°C to 70°C (C grade) and packaged in SOIC-14 without Pb-free exemption marking | No difference in circuit function; differs only in RoHS compliance status and tape-and-reel packaging | Select TL064CDR for standard commercial applications requiring full RoHS compliance and automated pick-and-place compatibility |
| TL074CDR | Higher 4.5 mA supply current per amplifier, 13 V/µs slew rate, and lower 10 nV/√Hz noise - but consumes 22× more power | Better for wideband audio or fast-settling data acquisition; unsuitable where <1 mA total quiescent current is required | Choose TL074CDR only when bandwidth or noise performance outweighs power budget constraints - not a drop-in replacement |
Compared with TL064BCNE4, TL064CDR offers identical performance with updated environmental compliance, while TL074CDR trades 22× higher supply current for 3.7× faster slew rate and 3× lower noise - making it appropriate only for bandwidth-critical, mains-powered systems.

FAQ
What is the operating temperature range for TL064BCNE4?
The TL064BCNE4 is specified for operation from 0°C to 70°C ambient temperature (Commercial grade). Its electrical characteristics - including input offset voltage (2 mV max), supply current (200 µA typical), and common-mode range - are guaranteed across this full range, making it suitable for indoor consumer and office equipment where thermal management is limited.
Does TL064BCNE4 support single-supply operation?
TL064BCNE4 is designed for dual-supply operation (±5 V to ±15 V), but can be used in single-supply configurations with proper biasing. Its common-mode input range extends to VCC+, allowing the non-inverting input to accept signals near the positive rail - however, the VCC− pin must still be connected to a defined reference (e.g., virtual ground), and output swing remains asymmetric without rail-splitting.
What is the maximum load capacitance TL064BCNE4 can drive stably?
TL064BCNE4 is unity-gain stable and characterized with 100 pF load capacitance in its pulse response test circuit (Figure 6-13). Driving >100 pF directly may cause peaking or ringing; for capacitive loads exceeding 100 pF, a series resistor (≥100 Ω) should be placed between the TL064BCNE4 output and the load to isolate capacitance and maintain phase margin.
How does TL064BCNE4 compare to TL064ACNE4 in precision applications?
TL064BCNE4 specifies tighter input offset voltage (2 mV max vs. 3 mV max for TL064ACNE4) and lower input offset current (5 pA typical vs. 30 pA), making it preferable for high-accuracy DC-coupled amplifiers, precision transducer interfaces, and low-drift integrators where offset drift contributes significantly to system error.
Is TL064BCNE4 pin-compatible with other quad op amps in SOIC-14?
TL064BCNE4 uses the industry-standard SOIC-14 pinout defined for quad op amps (e.g., LM324, TL074, TL084), with identical channel ordering and power pin locations (Pins 4 and 8). However, differences in input stage topology (JFET vs. bipolar), supply current, and ESD structure mean functional substitution requires verification of bias current, noise, and stability requirements - it is not a blind drop-in replacement.
