The CA3280E is a dual operational transconductance amplifier (OTA) from SIL, featuring a 9MHz bandwidth. This device is designed to reduce initial input offset voltage and offset voltage variation, minimizing "AGC thump" in control systems. Its design emphasizes reduced dependence on thermal and processing variables through interdigitation.
The CA3280E functions as a voltage amplifier but is characterized by transconductance rather than voltage gain, with a current output. The output current magnitude is the product of transconductance and input voltage. This makes it a versatile building block for applications such as voltage-controlled amplifiers, multipliers, demodulators, and instrumentation amplifiers.
Key features include low initial input offset voltage (500µV max for CA3280A), low offset voltage drift (5µV/°C max for CA3280A), and excellent matching between the two amplifiers. It supports a flexible supply voltage range from ±2V to ±15V and is available in PDIP and CERDIP packages.
This OTA was first introduced in 1969 and has found wide acceptance in instrumentation and audio applications, including linearization of transducer outputs, standardization of signals for data processing, and high-speed comparators.
