Texas Instruments TL064ACDRE4

Overview

TL064ACDRE4 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 V_CC+), and 1 MHz unity-gain bandwidth across 0°C to 70°C operation.

For engineers reviewing the TL064ACDRE4 datasheet, TL064ACDRE4 pinout, TL064ACDRE4 application, or TL064ACDRE4 equivalent, this page provides verified electrical 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 TL064ACDRE4 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) and low input bias current (30 pA typ at 25°C) minimize loading on high-impedance sensors and passive networks.

It features rail-to-rail output swing capability (±10 V into 10 kΩ), latch-up-free operation, and integrated EMI/RF filtering - critical for noise-prone environments like motor-driven white goods and tablet power management circuits.

FAQ

What is the maximum supply voltage rating for TL064ACDRE4?

The absolute maximum supply voltage for TL064ACDRE4 is ±18 V, but the recommended operating range is ±5 V to ±15 V. Operation beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, especially in the SOIC-14 package where R_θJA is 86°C/W. Always include 100 nF ceramic decoupling capacitors at each supply pin.

Does TL064ACDRE4 support single-supply operation?

Yes, TL064ACDRE4 supports single-supply operation when a virtual ground (e.g., V_CC/2 reference) is provided to the non-inverting inputs and output swing is constrained within the valid common-mode range. Its ability to accept inputs up to V_CC+ simplifies high-side sensing in 3.3 V or 5 V systems without level-shifting circuitry.

How does the input offset voltage of TL064ACDRE4 compare to TL064CDR?

TL064ACDRE4 has a maximum input offset voltage of 3 mV at 25°C, while TL064CDR is rated at 6 mV max. This tighter specification makes TL064ACDRE4 preferable for DC-critical applications like precision current sensing or thermocouple amplification where initial offset directly impacts measurement accuracy.

Is TL064ACDRE4 pin-compatible with TL074 or TL084?

Yes, TL064ACDRE4 is pin-compatible with TL074CDR and TL084CDR in the SOIC-14 package. All share identical pinout, footprint, and terminal functions - enabling drop-in replacement where lower power consumption and rail-inclusive input range are acceptable trade-offs for reduced bandwidth and slew rate.

What thermal considerations apply to TL064ACDRE4 in continuous operation?

At maximum recommended supply (±15 V) and no load, TL064ACDRE4 dissipates 6 mW per amplifier (24 mW total). With R_θJA = 86°C/W, junction temperature rise is ~2.1°C above ambient - well within the 150°C limit. For high-ambient or high-load conditions, verify PCB copper area and airflow per TI's SLMA002B layout guidelines.
