USC1841-BI-P20

The USC1841-BI-P20 is designed as one kind of universal semiconductors which 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 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.

USC1841-BI-P20 has five features. (1)Four 8-bit voltage output DACs. (2)Microprocessor peripheral. (3)TTL/CMOS compatible. (4)Single 5 to 15V supply. (5)3us settling time typical. Those are all the main features.

Some absolute maximum ratings of USC1841-BI-P20 have been concluded into several points as follow. (1)Its DC supply voltage would be 18V. (2)Its logic input voltage would be from Vdgnd-0.3V to Vdd+0.3V. (3)Its Vref would be from Vss to Vdd. (4)Its Idd supply would be 20mA max. (5)Its operating temperature range would be from -25°C to 85°C for industrial and would be from -55°C to 125°C for military. (6)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of USC1841-BI-P20 are concluded as follow. (1)Its resolution would be 8bits. (2)Its total unadjustable error would be max +/-1LSB. (3)Its differential nonlinearity would be max +/-1/2 LSB. (4)Its reference input would be min 4kohms for resistance and would be max 300pF for capacitance. (5)Its input voltage low would be max 0.8V. (6)Its input voltage high would be min 2.4V. (7)Its input leakage current would be max 1.0uA. (8)input capacitance would be max 8pF. (9)Its output swing would be from 0V to Vcc-3V. And so on.
