DAC7643VFBT

16位，双电压输出数位类比转换器 16-Bit, Dual Voltage Output DIGITAL-TO-ANALOG CONVERTER

DESCRIPON

The DAC7642 and DAC7643 are dual channel, 16-bit, voltage output Digital-to-Analog Converters DACs which pro vide 15-bit monotonic performance over the specified temperature range. They accept 16-bit parallel input data, have double-buffered DAC input logic allowing simultaneous up

date of all DACs, and provide a readback mode of the internal input registers. Programmable asynchronous reset clears all registers to a mid-scale code of 8000HDAC7642 or to a zero-scale code of 0000H DAC7643. These DACs can operate from a single +5V supply or from +5V and –5V supplies, providing an output range of 0 to +2.5V or –2.5V to +2.5V, respectively.
