    Products Detail

    The U440/441 are matched pairs of JFETs mounted in a hermetically-sealed TO-71 package. The two-chip design reduces parasitics, ensuring better performance at very high frequencies and extremely tight matching. These devices feature low gate leakage (1 pA), low noise, high CMRR (85 dB), and are ideal for wideband differential amplifiers in demanding test and measurement applications. They offer improved op-amp speed, settling time accuracy, and minimal input error.

    Key Features

    • Two-Chip Design
    • Minimum Parasitics
    • High Slew Rate
    • High-Frequency Performance
    • Low Offset/Drift Voltage
    • Low Gate Leakage: 1 pA
