DAC8420是一款四通道、12位电压输出DAC，配有串行数字接口，采用16引脚封装。该器件该单芯片器件采用BiCMOS技术制造，拥有非同一般的高电路密度和低功耗特性。简单易用的串行数字输入和完全缓冲的模拟电压输出无需外部器件便可实现额定性能。
With minimal additional circuitry, the three-wire serial digital input is easily interfaced with a microprocessor operating at 10 MHz. The address of each DAC is determined individually by a 16-bit serial word, which consists of a 12-bit data word and an address table header. User-Programmable Reset Control The CLR forces all four DACs to output zero or intermediate levels, asynchronously overwriting the current DAC register values. The user determines the output voltage range by setting the input VREFHI and VREFLO to achieve positive/negative unipolar or bipolar signal swing over the supply voltage range, providing great design flexibility.
DAC8420 is available in 16-pin PDIP, SOIC, and CERDIP packages with a power supply range of +5 V to ±15 V and a voltage reference range of +2.5 V to ±10 V. Power consumption is less than 255 mW (maximum) when powered from a ± 15 V supply; When powered from a +5 V supply, the power consumption is only 35 mW (maximum).
