MAX5101 19-1560 Rev 1 7/05 +2.7V to +5.5V, Low-Power, Triple, Parallel 8-Bit DAC with Rail-to-Rail Voltage Outputs General Description Features The MAX5101 parallel-input, voltage-output, triple 8-bit +2.7V to +5.5V Single-Supply Operation digital-to-analog converter (DAC) operates from a sin- Ultra-Low Supply Current gle +2.7V to +5.5V supply and comes in a space-sav- 0.3mA while Operating ing 16-pin TSSOP package. Internal precision buffers swing rail-to-rail. For all three DACs, the internal refer- 1A in Software Shutdown Mode ence voltage is tied to V . DD Ultra-Small 16-Pin TSSOP Package The MAX5101 has separate input latches for each of its Output Buffer Amplifiers Swing Rail-to-Rail three DACs. Data is transferred to the input latches from a common 8-bit input port. The DACs are individu- Power-On Reset Sets All Registers to Zero ally selected through address inputs A0 and A1 and are updated by bringing WR low. The MAX5101 features a 1A software shutdown mode, as well as a power-on reset mode that resets all regis- ters to code 00 hex on power-up.
