DAC8420FPZ

DAC8420 is a quad, 12bit voltage-output DAC with serial digital interface. Utilizing BiCMOS technology, this monolithic device features unusually high circuit density and low power consumption. The simple, easy-to-use serial digital input and fully buffered analogue voltage outputs require no external components to achieve a specified performance. The 3-wire serial digital input is easily interfaced to microprocessors running at 10MHz with minimal additional circuitry. The user programmable reset control CLR forces all four DAC outputs to either zero scale or midscale, asynchronously overriding the current DAC register values. The output voltage range, determined by the inputs VREFHI and VREFLO, is set by the user for positive or negative unipolar or bipolar signal swings within the supplies, allowing considerable design flexibility. It is widely used in application such as software controlled calibration, servo controls, process control and automation, ATE etc.
