DAC0890 Datasheet | National Semiconductor

Description The DAC0890 is a plete dual 8-bit voltage output digitalto-analog converter that can operate on a single 5V supply It includes on-chip output amplifiers precision bandgap voltage reference and full microprocessor interface Each DAC0890 output amplifier has two externally selectable output ranges 0V to 2 55V and 0V to 10 2V The amplifiers are internally trimmed for offset and full-scale accuracy and therefore require no external user trims The DAC0890 is supplied in 20-pin ceramic DIP package Y Y Y Y Y Y Guaranteed monotonic over temperature Internal precision bandgap reference Two calibrated output ranges 2 55V and 10 2V 2 ms settling time for full-scale output change No external trims Microprocessor interface Applications Features Industrial processing controls Automotive controls Disk drive motor controls Automatic test equipment Two 8-bit voltage output DACs 4 75V to 16 5V single operation Block Diagram TL H 10592 - 1 Ordering Information Industrial (b40 C s TA s a 85 C) DAC0890CIJ Package J20A Cerdip Connection Diagram Dual-In-Line Package TL H 10592 - 2 Top View C1995 National Semiconductor Corporation TL H 10592 RRD-B30M115 Printed in U S A Absolute Maximum Ratings (Notes 1 2) Soldering Information J package (10 sec ) Storage Temperature Junction Temperature 300 C b 65 C to 150 C If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Positive Supply Voltage (V a ) Voltage at Any Pin (Note 3) Input Current at Any Pin (Note 3) Package Input Current (Note 4) Power Dissipation (Note 5) ESD Susceptability (Note 6) Output Short-Circuit Protection Duration 20V GND b0 3 to V a a 0 3V 5 m A 20 m A 1 0W 2000V Indefinite (Note 5) 2) Operating Ratings (Notes 1 Temperature Range TMIN s TA s TMAX DAC0890CIJ Positive Supply Voltage V a b 40 C s TA s a 85 C 4 75 to 16 5V Electrical Characteristics The following specifications apply...
