The DAC8420ESZ is a quad 12-bit voltage-output Digital-to-analog Converter (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 analog 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. Each DAC 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 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.

• Guaranteed monotonic over temperature
• Excellent matching
• Buffered voltage outputs
