The device contains two ADCs, each preceded by a 2channel multiplexer, and a low noise, wide bandwidth trackand-hold amplifier that can handle input frequencies in excess of 10 MHz.
The AD7366 is fabricated on Analog Devices’ Industrial CMOS process, iCMOS, a technology platform combining the advantages of low and high voltage CMOS, bipolar and high voltage DMOS processes.
The process allows the AD7366 to accept high voltage bipolar signals in addition to reducing power consumption and package size.
The AD7366 can accept true bipolar analog input signals in the ±10 V range, ±5 V range and 0 to 10 V range.
The AD7366 has an on-chip 2.
5 V reference that can be overdriven if an external reference is preferred.
The AD7366 is available in a 24-lead TSSOP package.
iCMOSTM Process Technology For analog systems designers within industrial/instrumentation equipment OEMs who need high performance ICs at higher-voltage levels, iCMOS is a technology pla...
