STMicroelectronics TL064CDT Low-Power JFET-Input Operational Amplifier

The TL064CDT from STMicroelectronics is a highly-efficient operational amplifier that integrates advanced JFET-input technology to offer a perfect blend of low power consumption and high performance. It is designed to address the needs of a wide array of applications that require optimized power and speed, from consumer electronics to industrial control systems.

This operational amplifier features a quadruple layout, with four independent high-gain, internally frequency-compensated op-amps that are designed to operate from a single power supply. However, it can also function with dual supplies, providing flexibility in a variety of circuit configurations. The single supply voltage can range from 3V to 30V, while the dual supply voltage range is ±1.5V to ±15V, making the TL064CDT a versatile choice for designers.

The TL064CDT boasts a low input bias and offset currents, thanks to its JFET input stage. This characteristic ensures that the op-amp maintains a high input impedance, which minimizes the loading effect on upstream circuits. Additionally, the low input bias current makes it suitable for applications that require good low-frequency characteristics.

Another significant advantage of the TL064CDT is its low power consumption. With a typical power supply drain of just 200 µA—significantly lower than that of standard bipolar input operational amplifiers—this device is ideal for battery-powered electronics and other applications where energy efficiency is paramount.

The device also features a wide common-mode (up to VCC+) and differential voltage range, providing enhanced linearity for better signal processing performance. Its high slew rate of 3.5 V/µs ensures fast response times, which is essential for applications requiring rapid signal amplification or conditioning.

STMicroelectronics packages the TL064CDT in a compact SO-14 surface-mount package, which allows for high-density mounting and is suitable for automated assembly processes. The combination of its low power profile, robust performance, and packaging makes the TL064CDT an excellent choice for designers looking to optimize their systems for power efficiency and operational excellence.

Overall, the TL064CDT operational amplifier is a reliable and cost-effective solution for a multitude of electronic applications, striking an optimal balance between power conservation and operational capability.
