The LF444CN is a quad low power JFET input operational amplifier from Texas Instruments, designed to provide improved DC characteristics compared to the LM148 while maintaining similar AC performance. It features a low supply current of 200 OºA per amplifier, making it suitable for battery-powered applications. The amplifier has a high input impedance of 10^12 Oc and low input bias current of 50 pA maximum, which minimizes loading effects on the preceding stages. With a gain bandwidth product of 1 MHz and a slew rate of 1 V/Oºs, the LF444CN is capable of handling a variety of signal processing tasks. It also exhibits low noise characteristics, with an equivalent input noise voltage of 35 nV/,àöHz and an input noise current of 0.01 pA/,àöHz. The device is pin-compatible with the LM148, allowing for easy upgrades in existing designs. The LF444CN is suitable for applications where low power dissipation and high performance are critical.
