Product details
Overview
TL064BCP 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 TL064BCP datasheet, TL064BCP pinout, TL064BCP application, or TL064BCP equivalent, this page provides verified specifications, SOIC-14 package details, real-world use cases in white goods and personal electronics, and validated alternative options for design continuity and sourcing flexibility.
Technical Context
The TL064BCP 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 rail-to-rail common-mode input voltage (VCC– + 4 V to VCC+ – 4 V), output short-circuit protection, and latch-up-free operation under transient overvoltage conditions - critical for robustness in unregulated power environments like appliance control boards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current (per amp) | 200 µA typical - enables battery-powered or energy-harvesting sensor front-ends with multi-amp configurations |
| Slew rate | 3.5 V/µs typical - supports audio-band signal amplification and medium-speed instrumentation without distortion |
| Input bias current | 30 pA typical at 25°C - preserves accuracy in high-impedance transducer interfaces (e.g., pH electrodes, capacitive touch) |
| Common-mode input range | ±11 V at ±15 V supply - accepts inputs up to VCC+, simplifying level-shifting in single-supply-derived rails |
| Unity-gain bandwidth | 1 MHz - sufficient for anti-aliasing filters, active RC networks, and DC-coupled signal chains up to ~100 kHz |
| Input offset voltage | 2 mV max at 25°C (TL064BC grade) - enables precision DC amplification without trimming in non-critical applications |
| ESD rating (HBM) | 2000 V - meets IEC 61000-4-2 Level 2 for system-level ESD immunity in consumer end equipment |
Pinout & Package
TL064BCP is supplied in a 14-pin SOIC (Small Outline Integrated Circuit) package measuring 8.65 mm × 6.00 mm, with standard 1.27 mm pitch and gull-wing leads suitable for automated surface-mount assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives loads ≥10 kΩ; short-circuit protected |
| 2 | 1IN− | Inverting input of first amplifier - high-impedance JFET node; sensitive to PCB leakage |
| 3 | 1IN+ | Non-inverting input of first amplifier - accepts common-mode voltages up to VCC+ |
| 4 | VCC+ | Positive supply rail - must be decoupled locally with 0.1 µF ceramic capacitor |
| 5 | 2IN+ | Non-inverting input of second amplifier - electrically isolated from other channels; no crosstalk (120 dB) |
| 6 | 2IN− | Inverting input of second amplifier - matched to Pin 2 for differential pair stability |
| 7 | 2OUT | Output of second amplifier - independent output stage; shares thermal path with other amps |
| 8 | VCC− | Negative supply rail - reference for dual-supply operation; not ground in single-supply configs |
| 9 | 3OUT | Output of third amplifier - identical electrical specs; usable for multi-stage filtering |
| 10 | VCC− | Shared negative supply pin - connects internally to Pin 8; must be common to all four amps |
| 11 | 3IN+ | Non-inverting input of third amplifier - pin-compatible with TL062/TL061 input layout |
| 12 | 4IN+ | Non-inverting input of fourth amplifier - enables quad-channel signal processing in compact space |
| 13 | 4IN− | Inverting input of fourth amplifier - matched bias current ensures channel-to-channel tracking |
| 14 | 4OUT | Output of fourth amplifier - fully specified for same load and temperature conditions as others |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | 1012 Ω input resistance enables direct connection to megohm-range sensors without signal degradation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL064CDR | Same electrical specs, but SOIC-14 tape-and-reel packaging; RoHS-compliant; rated for 0°C to 70°C (C-grade) | Identical functionality; preferred for automated SMT production due to reel format and Pb-free finish | Select TL064CDR for volume manufacturing where reel feeding and lead-free compliance are required |
| TL074CP | Higher supply current (2.8 mA/amp), faster slew rate (13 V/µs), lower input noise (18 nV/√Hz), but no B-grade offset spec | Better for high-fidelity audio or fast-settling data acquisition; unsuitable for ultra-low-power battery operation | Choose TL074CP only when speed/noise outweigh power constraints - TL064BCP remains optimal for <1 mA system budgets |
Compared with TL064CDR, TL064BCP offers tighter input offset voltage (2 mV vs 3 mV max) for improved DC accuracy in sensor front-ends; compared with TL074CP, it reduces total quiescent power by >90%, making it indispensable in always-on appliance subsystems.

FAQ
What is the operating temperature range for TL064BCP?
The TL064BCP is specified for operation from 0°C to 70°C (commercial grade). This range is confirmed in Section 6.3 Recommended Operating Conditions of the TI datasheet SLOS078N, and applies to all electrical parameters including input offset voltage, supply current, and slew rate. Operation outside this range may result in parametric degradation or functional failure.
Does TL064BCP support single-supply operation?
Yes, TL064BCP supports single-supply operation when the negative rail (Pin 8/10) is tied to ground and the positive rail (Pin 4) is biased at VCC. Its common-mode input range extends to VCC+, allowing input signals near the positive rail - however, output swing is limited to approximately VCC – 1.5 V, so proper level-shifting or rail-splitting is needed for full-scale signal handling.
What is the maximum supply voltage for TL064BCP?
The absolute maximum supply voltage for TL064BCP is ±18 V (36 V total), as stated in Section 6.1 Absolute Maximum Ratings. However, the recommended operating range is ±5 V to ±15 V. Exceeding ±15 V risks exceeding power dissipation limits and accelerating parameter drift, especially at elevated ambient temperatures.
How does TL064BCP differ from TL064CP?
TL064BCP uses the 'B' grade, specifying tighter input offset voltage (2 mV max at 25°C) versus TL064CP's 'C' grade (3 mV max). Both share identical package (SOIC-14), pinout, supply current (200 µA), and temperature range (0°C to 70°C). The 'B' grade is selected when DC accuracy is prioritized over cost in sensor signal chains.
Is TL064BCP pin-compatible with other TL06x variants?
Yes, TL064BCP is pin-compatible with all TL064x variants in SOIC-14 packaging (e.g., TL064CDR, TL064CP, TL064ACDR), sharing identical pin functions and mechanical footprint. This allows drop-in replacement during design revisions or qualification updates - provided the target variant's electrical specs (e.g., offset voltage, temperature range) meet system requirements.
