概述 the max551/max552 are 12-bit,current-output, 4-quadrant multiplying digital-to-analog converters(dacs). these devices are capable of providing unipolar or bipolaroutputs when operating from either a single +5v (max551) or +3v(max552) power supply. an internal power-on-reset circuit clearsall dac registers on power-up, setting the dac output voltage to0v. the spi?/qspi? and microwire?-compatible 3-wire serial interfacesaves board space and reduces power dissipation compared withparallel-interface devices. the max551/max552 featuredouble-buffered interface logic with a 12-bit input register and a12-bit dac register. data in the dac register sets the dac outputvoltage. data is loaded into the input register through the serialinterface. the active-low load input transfers data from the inputregister to the dac register, updating the dac output voltage. themax551/max552 are available in an 8-pin dip package or aspace-saving 10-pin μmax package. the μmax package provides anasynchronous clear (clr-bar) input that clears all dac registerswhen pulled to gnd, setting the output voltage to 0v 关键特性 single-supply operation: +4.5v to+5.25v (max551) +2.7v to+3.6v (max552) 12.5mhz3-wire serial interface spi/qspi and microwire compatible power-on reset clears dac output to zero asynchronous clear input clears dac output to zero voltagemode or bipolar mode operation with a single power supply schmitt-trigger digital inputs for direct optocouplerinterface 0.4μasupply current 10-pinμmax package 应用/使用 μp控制系统 自动校准 数控滤波器 增益调节 运动控制系统 过程控制i/o板 可编程放大器/衰减器 变送器驱动器
