Analog Microelectronics AM411
AM411 is a universal voltage amplifier / transmitter IC for signal-conditioning applications. It converts a differential input voltage into an amplified, single-ended output voltage. The IC consists of an instrumentation amplifier with adjustable offset as input stage and an operational amplifier output stage with adjustable gain.APPLICATIONS
