Product details
Overview
TL064CDE4 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 TL064CDE4 datasheet, TL064CDE4 pinout, TL064CDE4 application, or TL064CDE4 equivalent, this page provides verified electrical parameters, 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 TL064CDE4 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 output short-circuit protection. The device maintains 80 dB CMRR and 80 dB PSRR at 25°C, with crosstalk attenuation of 120 dB between channels - critical for multi-channel instrumentation where inter-channel coupling must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables battery-powered or energy-harvesting systems to operate >1 year on coin-cell power |
| Slew Rate | 3.5 V/µs typical - supports clean amplification of audio-band signals up to ~100 kHz without distortion |
| Input Bias Current | 30 pA typical at 25°C - preserves signal integrity in high-impedance sensor interfaces (e.g., pH electrodes, capacitive touch) |
| Common-Mode Range | –12 V to +15 V (with ±15 V supplies) - accepts inputs beyond VCC–, simplifying level-shifting in mixed-voltage systems |
| Unity-Gain Bandwidth | 1 MHz - sufficient for active filters, transducer signal conditioning, and precision DC-coupled gain stages |
| Input Offset Voltage | 3 mV max at 25°C - enables accurate DC measurement in 12-bit ADC front-ends without trimming |
| ESD Rating | 1.5 kV CDM - meets IEC 61000-4-2 Level 2 for robustness in assembly and field environments |
Pinout & Package
TL064CDE4 is housed 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 SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives loads ≥10 kΩ with ±10 V swing under full temperature range |
| 2 | 1IN– | Inverting input of first amplifier - high-impedance node (1012 Ω) sensitive to PCB leakage and guarding requirements |
| 3 | 1IN+ | Non-inverting input of first amplifier - accepts common-mode voltages up to VCC+, enabling single-supply biasing |
| 4 | VCC+ | Positive power supply terminal - must be decoupled with 0.1 µF ceramic capacitor near pin |
| 5 | 2IN+ | Non-inverting input of second amplifier - electrically isolated from Channel 1; no shared substrate coupling |
| 6 | 2IN– | Inverting input of second amplifier - matched to Pin 2 for differential pair symmetry in dual configurations |
| 7 | 2OUT | Output of second amplifier - exhibits <120 dB crosstalk isolation from Channel 1 at 1 kHz |
| 8 | VCC– | Negative power supply terminal - reference for all four amplifiers; requires low-impedance return path |
| 9 | 3OUT | Output of third amplifier - identical AC/DC specs to Pins 1 and 7; usable for multi-stage filtering |
| 10 | VCC– | Shared negative supply - not a dedicated ground; connects internally to Pin 8 |
| 11 | 3IN+ | Non-inverting input of third amplifier - pin-compatible with TL062 and TL061 for layout reuse |
| 12 | 4IN+ | Non-inverting input of fourth amplifier - supports independent configuration without channel interaction |
| 13 | 4IN– | Inverting input of fourth amplifier - matches input capacitance (≈3 pF) and bias current of other channels |

Key Features
| Feature | Design Value |
|---|---|
| JFET-input architecture | Enables 1012 Ω input resistance and sub-100 pA bias current - critical for microamp-level sensor signal integrity |
| Internal frequency compensation | Guarantees stability at unity gain without external compensation components - reduces BOM count and layout area |
| Output short-circuit protection | Prevents latch-up or permanent damage during accidental shorts - eliminates need for external current-limiting resistors |
| Latch-up-free process | Ensures immunity to destructive parasitic thyristor activation under overvoltage or ESD stress - improves field reliability |
| High ESD tolerance (1.5 kV CDM) | Reduces risk of assembly-line failures and field returns in unshielded consumer enclosures |

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 |
|---|---|---|---|
| TL074CDR | Higher supply current (2.5 mA vs 0.8 mA total), 13 V/µs slew rate, lower input bias current (10 pA) | Better for wideband audio or fast-settling data acquisition; less suitable for battery-constrained designs | Select TL074CDR when bandwidth and speed outweigh power budget constraints |
| TL084CDR | Higher noise (18 nV/√Hz vs 30 nV/√Hz), higher input bias current (300 pA), same 13 V/µs slew rate | Preferred for general-purpose analog functions where cost is primary and ultra-low bias current is not required | Choose TL084CDR for legacy designs requiring drop-in compatibility with older TL08x-based layouts |
Compared with TL064CDE4, TL074CDR offers superior speed but consumes 12× more quiescent power, while TL084CDR trades input bias performance for broader production availability and lower unit cost - making TL064CDE4 optimal for power-sensitive, high-impedance sensor front-ends.

FAQ
What is the operating temperature range for TL064CDE4?
The TL064CDE4 is rated for commercial temperature operation from 0°C to 70°C. This range is confirmed in Section 6.3 (Recommended Operating Conditions) of the TI datasheet SLOS078N, and applies to all electrical specifications unless otherwise noted. Designs requiring extended temperature support should consider TL064I or TL064M variants instead of TL064CDE4.
Does TL064CDE4 support single-supply operation?
Yes, TL064CDE4 supports single-supply operation when biased appropriately. Its common-mode input voltage range extends to VCC+, allowing the non-inverting input to accept signals up to the positive rail. For true single-supply use, VCC– must be tied to ground and VCC+ set to the desired supply voltage (5 V to 15 V), with input signals referenced to mid-rail via resistor dividers or charge pumps.
What is the maximum output voltage swing for TL064CDE4?
TL064CDE4 delivers a maximum peak output voltage swing of ±10 V into a 10 kΩ load with ±15 V supplies at 25°C, as specified in Table 6-7. Under full temperature range (0°C to 70°C), the guaranteed minimum swing remains ±10 V, while typical performance reaches ±13.5 V - enabling robust headroom for analog signal processing before clipping occurs.
Is TL064CDE4 pin-compatible with other TL06x variants?
Yes, TL064CDE4 shares identical pinout and footprint with all TL064x variants in SOIC-14 packaging (e.g., TL064ACDE4, TL064BCDE4, TL064IDE4). Pin assignments match Figure 5-3 and Table 5-1 in the datasheet, ensuring mechanical and electrical interchangeability across speed-grade and temperature-grade versions within the same package type.
How does TL064CDE4 compare to LM324 in low-power applications?
TL064CDE4 draws only 200 µA per amplifier versus LM324's 1.2 mA per amplifier - reducing total quiescent current by 83%. Its JFET input also provides 1012 Ω impedance and 30 pA bias current, compared to LM324's bipolar input (200 kΩ, 45 nA), making TL064CDE4 far superior for high-impedance sensor interfaces where loading and drift must be minimized.
