Product Summary

The DAC8420ESZ is a quad, 12-bit voltage-output DAC with serial digital interface, in a 16-pin package. 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 analog voltage outputs require no external components to achieve specified performance. The three-wire serial digital input is easily interfaced to microprocessors running at 10 MHz rates, with minimal additional circuitry. The DAC8420ESZ is addressed individually by a 16-bit serial word consisting of a 12-bit data word and an address header. The user-programmable reset control CLR forces all four DAC outputs to either zero or midscale, asynchronously overriding the current DAC register values. The output voltage range of the DAC8420ESZ, 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.
