The LF444ACN is a quad low power JFET input operational amplifier from Texas Instruments, designed for applications requiring low power consumption and high performance. It features a supply current of only 200 OºA per amplifier, which is one-fourth that of the LM148, while maintaining similar AC characteristics. The amplifier has a high gain bandwidth of 1 MHz and a slew rate of 1 V/Oºs. It exhibits low input bias current of 50 pA (maximum) and low noise voltage of 35 nV/,àöHz, making it suitable for precision applications. The input impedance is exceptionally high at 10^12 Oc, which minimizes loading effects on the preceding stage. The LF444ACN is pin-compatible with the LM148, allowing for easy integration into existing designs. It is ideal for low power dissipation applications where good electrical characteristics are critical.
