Rochester re-introduces CA3080 micropower op amp
Authorised by Harris/Intersil to continue manufacturing the CA3080 and CA3080A operational transconductance amplifier (OTA), Rochester’s Extension-of-Life program provides a continuous supply of the 2MHz amplifiers. The CA3080 and CA3080A amplifiers are Gatable-Gain Blocks that utilise the unique OTA concept.
The amplifiers have differential input and single-ended, push-pull, class A output. In addition, these devices have an amplifier bias input that can be used either for gating or for linear gain control. The CA3080 and CA3080A amplifiers also have a high output impedance and their transconductance (gM) is directly proportional to the amplifier bias current (IABC).
Delivering an excellent slew rate (50/µs), and because power is consumed only when devices are in the “ON” channel state, the CA3080 and CA3080A amplifiers are ideal for multiplexer and fast unity-gain voltage followers.
