MAX5102 19-1565 Rev 0 10/99 +2.7V to +5.5V, Low-Power, Dual, Parallel 8-Bit DAC with Rail-to-Rail Voltage Outputs General Description Features The MAX5102 parallel-input, voltage-output, dual 8-bit +2.7V to +5.5V Single-Supply Operation digital-to-analog converter (DAC) operates from a single Ultra-Low Supply Current +2.7V to +5.5V supply and comes in a space-saving 0.2mA while Operating 16-pin TSSOP package. Internal precision buffers swing Rail-to-Rail , and the reference input range 1nA in Shutdown Mode includes both ground and the positive rail. Both DACs Ultra-Small 16-Pin TSSOP Package share a common reference input. Ground to V Reference Input Range DD The MAX5102 has separate input latches for each of its DACs. Data is transferred to the input latches from a Output Buffer Amplifiers Swing Rail-to-Rail common 8-bit input port. The DACs are individually Power-On Reset Sets All Registers to Zero selected through address input A0 and are updated by bringing WR low. The MAX5102 features a shutdown mode that reduces current to 1nA, as well as a power-on reset mode that resets all registers to code 00 hex on power-up. Ordering Information INL PART TEMP.
