MAX514BCWI+

The MAX514BCWI+ is a CMOS, quad, 12bit serial input multiplying digital to analogue converter (DAC) in 28 pin WSOIC package. It contains four 12bit R-2R multiplying DACs each with serial-in parallel-out shift register, DAC register and control logic. The 3-wire serial interface design of MAX514 minimizes number of package pins and internal level translators, so it uses less board space and dissipates less power (10mW maximum) than parallel interface devices. The MAX514 minimizes digital-noise feed-through from its logic input pins to its analogue output when used with microprocessors (µPs) with serial port. This device uses low tempco thin film resistors which are laser trimmed to ±1LSB linearity with gain accuracy better than ±1.5LSB. It is specified with a +5V power supply and used in µP controlled systems, arbitrary waveform generation (AWG), automatic test equipments, digital offset/gain adjustment, motion control systems and programmable amplifiers/attenuators.
