DAC8426FSZ

DAC8426 is a complete quad voltage output D/A converter with internal reference. It fits directly into any existing 7226 socket where the user currently has a 10V external reference. The external reference is no longer necessary. It contains four 8bit voltage-output CMOS D/A converters on a single chip. The circuit also includes four input latches and interface control logic. One of the four latches, selected by the address inputs, is loaded from the 8bit data bus input when the write strobe is active low. The on-board amplifiers can drive up to 10mA from either a single or dual supply. Its compact size, low power, and economical cost-per-channel, make the DAC8426 attractive for applications requiring multiple D/A converters without sacrificing circuit-board space system reliability is also increased due to reduced parts count. Application includes process controls, multichannel microprocessor controlled, system calibration, Op-amp offset and gain adjust, level and threshold setting.
