LS320 BiFET Amplifier Linear Systems High Input Impedance BiFET Amplifier The LS320 is a high input impedance amplifier produced using a BiFET process and packaged in TO-92. The TO-92 package is well suited for cost sensitive applications and mass production. (See Packaging Information). LS320 Features: High Input Impedance High Transconductance FEATURES HIGH INPUT IMPEDANCE rGs ≥ = 100GΩ HIGH TRANSCONDUCTANCE YFS = 30,000µS ABSOLUTE MAXIMUM RATINGS 1@ 25°C (unless otherwise noted) Maximum Temperatures Storage Temperature Operating Junction Temperature Maximum Power Dissipation Continuous Power Dissipation @ +125°C Maximum Currents Drain Current Maximum Voltages Drain to Source Gate to Source ELECTRICAL CHARACTERISTICS @ 25°C (unless otherwise noted) SYMBOL CHARACTERISTICS MIN.
