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
SOT-23.
The SOT-23 package is well suited for cost sensitive
applications and mass production.
(See Packaging Information).
LS320 Features:
High Input Impedance
High Transconductance
