MAX5100 19-1557 Rev 0 10/99 +2.7V to +5.5V, Low-Power, Quad, Parallel 8-Bit DAC with Rail-to-Rail Voltage Outputs General Description Features The MAX5100 parallel-input, voltage-output, quad 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- 0.4mA while Operating ing 20-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. All four Ultra-Small 20-Pin TSSOP Package DACs share a common reference input. Ground to V Reference Input Range DD The MAX5100 provides double-buffered logic inputs: four 8-bit buffer registers followed by four 8-bit DAC Output Buffer Amplifiers Swing Rail-to-Rail registers. This keeps the DAC outputs from changing Double-Buffered Registers for Synchronous during the write operation. An asynchronous control Updating pin, LDAC, allows for simultaneous updating of the DAC registers. Power-On Reset Sets All Registers to Zero The MAX5100 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.
