Texas Instruments TL064BCDG4

Overview

TL064BCDG4 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 TL064BCDG4 datasheet, TL064BCDG4 pinout, TL064BCDG4 application, or TL064BCDG4 equivalent, this page provides verified electrical parameters, SOIC-14 package details, real-world use cases in white goods and personal electronics, and two validated alternative op amps with documented functional and thermal differences.

Technical Context

The TL064BCDG4 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-Z sources like 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 meets 1.5 kV HBM ESD rating and integrates EMI/RF filtering for robustness in electrically noisy environments.

FAQ

What is the maximum operating temperature range for TL064BCDG4?

The TL064BCDG4 is rated for operation from 0°C to 70°C (commercial temperature grade). Its electrical specifications - including input offset voltage (2 mV max at 25°C), supply current (200 µA typ.), and common-mode range - are guaranteed across this full range. Operation beyond 70°C may cause parameter drift or accelerated aging; for extended temperature use, consider the TL064I variant rated to 85°C.

Does TL064BCDG4 support single-supply operation?

Yes, TL064BCDG4 supports single-supply operation with appropriate input biasing. Its common-mode input voltage range extends to V_CC+, allowing the non-inverting input to be biased at mid-supply (e.g., 2.5 V on a 5 V rail) while accepting signals from 0 V to V_CC+. Output swing is limited to approximately 1.5 V from each rail, so design margins must accommodate this headroom in rail-to-rail signal paths.

How does the input offset voltage of TL064BCDG4 compare to TL064CDR?

TL064BCDG4 guarantees a maximum input offset voltage of 2 mV at 25°C, whereas TL064CDR specifies 3 mV max under the same conditions. This 1 mV improvement directly reduces DC error in precision applications like weigh scales or medical sensor amplifiers. Both parts share the same 10 µV/°C temperature coefficient, so the offset advantage holds across the full 0°C–70°C range.

Can TL064BCDG4 replace TL074 in existing designs?

TL064BCDG4 is not a direct drop-in replacement for TL074 due to significantly lower slew rate (3.5 V/µs vs 13 V/µs) and bandwidth (1 MHz vs 3 MHz). While pin-compatible in SOIC-14, substituting TL064BCDG4 in high-speed applications - such as active filters above 100 kHz or video signal paths - will result in distortion and settling errors. It is suitable only where low power is prioritized over speed.

What decoupling is recommended for TL064BCDG4 power pins?

Each V_CC+ and V_CC– pin of TL064BCDG4 requires a 0.1 µF X7R ceramic capacitor placed within 2 mm of the pin and connected to a low-impedance ground plane. For systems with noisy digital supplies, add a 10 µF tantalum or aluminum electrolytic capacitor per supply rail at the board edge. Avoid shared vias between decoupling caps and analog signal returns to prevent ground bounce coupling.
