DAC102S085 Datasheet | National Semiconductor

Description Features n Guaranteed Monotonicity The DAC102S085 is a full-featured, general purpose DUAL n Low Power Operation 10-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7V to 5.5V supply and uses n Rail-to-Rail Voltage Output 210 µA at 3V and 320 µA at 5V. The DAC102S085 is n Power-on Reset to 0V packaged in a 10-lead MSOP package. The on-chip output n Simultaneous Output Updating amplifier allows rail-to-rail output swing and the three wire n Wide power supply range (+2.7V to +5.5V) serial interface operates at clock rates up to 40 MHz over the n Power Down Modes entire supply voltage range. petitive devices are limited to 25 MHz clock rates at supply voltages in the 2.7V to 3.6V Key Specifications range. The serial interface is patible with standard SPI™, QSPI, MICROWIRE and DSP interfaces. n Resolution 10 bits ± 2 LSB (max) n INL The reference for the DAC102S085 serves both channels and can vary in voltage between 1V and VA, providing the n DNL +0.35 / - 0.25 LSB (max) widest possible output dynamic range. The DAC102S085 n Settling Time 6 µs (max) has a 16-bit input shift register that controls the outputs to be n Zero Code Error +15 m V (max) updated, the mode of operation, the powerdown condition, n Full-Scale Error - 0.75 %FS (max) and the binary input data. Both outputs can be updated n Supply Current simultaneously or individually depending on the setting of - Normal 270 µA (3.6V) / 410 µA (5.5V) max the two mode of operation bits. - Pwr Down 20 n A (3.6V) / 30 n A (5.5V) typ A power-on reset circuit ensures that the DAC output powers up to zero volts and remains there until there is a valid write .
