Universal Semiconductor, Inc. USC1841

The USC1841 contains four 8 bit Digital to Analog Converters (DAC), with output amplifiers and digital interface logic and storage for each DAC. Full specified performance is achieved without trim. The chip contains 8 bit latches for each of the four DACs. Data transfer is over a common 8 bit bus into the four ports/latches. Lines A0 and A1 determine which port is loaded when WR goes low. Each DAC has an output buffer capable of driving 5mA. Performance is guarenteed for input reference voltages from 2 to 12 V. The USC1841 has been designed to operate with a single power supply.
