The No external capacitors required AD8574-EP is a quad amplifier, featuring rail-to-rail input and ENHANCED PRODUCT FEATURES output swings. It is guaranteed to operate from 2.7 V to 5 V single supply. Supports defense and aerospace applications (AQEC standard) Military temperature range (55C to +125C) The AD8574-EP provides benefits previously found only in Controlled manufacturing baseline expensive auto-zeroing or chopper stabilized amplifiers. Using a One assembly/test site patented spread spectrum, auto-zero technique, the AD8574 One fabrication site eliminates the intermodulation effects from interaction of the Product change notification chopping function with the signal frequency in ac applications. Qualification data available on request With an offset voltage of only 1 V and drift of 0.005 V/C, the APPLICATIONS AD8574-EP is perfectly suited for applications where error sources must be minimized. Temperature sensors Pressure sensors The AD8574-EP is specified for the military temperature range Precision current sensing (55C to +125C). The AD8574-EP quad amplifier is available in Strain gage amplifiers a 14-lead TSSOP package. Additional applications and technical information is available in the AD8571/AD8572/AD8574 data sheets.
