LF444 JFET-Input Operational Amplifier

The LF444 from Texas Instruments (TI) is a quad, JFET-input operational amplifier that integrates four independent high-speed amplifiers in a single package. This component is engineered with an FET input architecture, characterized by a low input bias current of 50 pA and a typical offset voltage of 5 mV. With a total supply voltage of 6 V and a gain bandwidth product of 1 MHz, it is well-suited for a variety of analog signal processing tasks. Its input common-mode range includes the positive rail, supporting design flexibility in single-supply systems. The LF444 is offered in a PDIP-14 package and is specified for the commercial temperature range of 0°C to 70°C, making it a reliable choice for cost-sensitive industrial control, audio processing, and active filter applications.
