FEATURES Guaranteed Monotonic Over Temperature Excellent Matching Between DACs Unipolar or Bipolar Operation Buffered Voltage Outputs High Speed Serial Digital Interface Reset to Zero- or Center-Scale Wide Supply Range, +5 V-Only 15 V Low Power Consumption (35 mW max) Available in 16-Pin DIP and SOL Packages APPLICATIONS Software Controlled Calibration Servo Controls Process Control and Automation ATE

The is a quad, 12-bit voltage-output DAC with serial digital interface, 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. Each DAC is addressed individually a 16-bit serial word consisting 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, 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.

The DAC8420 is available in 16-pin epoxy DIP, cerdip, and wide-body SOL (small-outline surface mount) packages. Operation is specified with supplies ranging from +5 V-only 15 V, with references 10 V respectively. Power dissipation when operating from 15 V supplies is less than 255 mW (max), and only 35 mW (max) with +5 V supply. For applications requiring product meeting MIL-STD-883, contact your local sales office for the DAC8420/883 data sheet, which specifies operation over the to +125�C temperature range.
