DAC081S101 www.ti.com SNAS323C – JUNE 2005 – REVISED FEBRUARY 2013 DAC081S101 8-Bit Micro Power Digital-to-Analog Converter with Rail-to-Rail Output Check for Samples: DAC081S101 FEATURES 1 23 Guaranteed Monotonicity Low Power Operation Rail-to-Rail Voltage Output Power-on Reset to Zero Volts Output SYNC Interrupt Facility Wide Power Supply Range (+2.7V to +5.5V) Small Packages Power Down Feature APPLICATIONS Battery-Powered Instruments Digital Gain and Offset Adjustment Programmable Voltage & Current Sources Programmable Attenuators DESCRIPTION The DAC081S101 is a full-featured, general purpose 8-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7V to 5.5V supply and consumes just 175 µA of current at 3.6 Volts. The on-chip output amplifier allows rail-to-rail output swing and the three wire serial interface operates at clock rates up to 30 MHz over the specified supply voltage range and is compatible with standard SPI™, QSPI, MICROWIRE and DSP interfaces. Competitive devices are limited to 20 MHz clock rates at supply voltages in the 2.7V to 3.6V range. The supply voltage for the DAC081S101 serves as its voltage reference, providing the widest possible output dynamic range. A power-on reset circuit ensures that the DAC output powers up to zero volts and remains there until there is a valid write to the device. A power-down feature reduces power consumption to less than a microWatt. The low power consumption an...
