Extended automotive operating temperature range 55C to +125C GENERAL DESCRIPTION Selectable zero-scale/midscale power-on presets The AD5547-EP is a dual precision, 16-bit, multiplying, low power, Compact 38-lead TSSOP package current-output, parallel input, digital-to-analog converter (DAC). It ENHANCED PRODUCT FEATURES is designed to operate from a single +5 V supply with 10 V Supports defense and aerospace applications (AQEC multiplying references for 4-quadrant outputs with a 6.8 MHz standard) bandwidth. Military temperature range (such as 55C to +125C). The built-in, 4-quadrant resistors facilitate resistance matching Controlled manufacturing baseline and temperature tracking, which minimize the number of One assembly/test site components needed for multiquadrant applications. In addition, One fabrication site the feedback resistor (RFB) simplifies the I-to-V conversion with Enhanced product change notification an external buffer. Qualification data available on request The AD5547-EP is available in a compact, 38-lead TSSOP APPLICATIONS package and operates at the extended automotive temperature Automatic test equipment range of 55C to +125C. Additional application and technical Instrumentation information can be found in the AD5547 data sheet.
