These types are especially applicable for multiplexer applications because power is consumed only when the devices are in the "ON" channel state. * Multiplier * Comparator Ordering Information PART NUMBER (BRAND) TEMP. RANGE (oC) CA3080 CA3080A PACKAGE The CA3080 and CA3080A types have differential input and a single-ended, push-pull, class A output. In addition, these types have an amplifier bias input which may be used either for gating or for linear gain control. These types also have a high output impedance and their transconductance (gM) is directly proportional to the amplifier bias current (IABC). PKG.
