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 The MAX5100 parallel-input, voltage-output, quad 8-bit digital-to-analog converter (DAC) operates from a single +2.7V to +5.5V supply and comes in a space-saving 20-pin TSSOP package. Internal precision buffers swing Rail-to-Rail ® , and the reference input range includes both ground and the positive rail. All four DACs share a common reference input. The MAX5100 provides double-buffered logic inputs: four 8-bit buffer registers followed by four 8-bit DAC registers. This keeps the DAC outputs from changing during the write operation. An asynchronous control pin, LDAC , allows for simultaneous updating of the DAC registers. 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. o Ultra-Low Supply Current 0.4mA while Operating 1nA in Shutdown Mode o Ultra-Small 20-Pin TSSOP Package o Ground to VDD Reference Input Range o Output Buffer Amplifiers Swing Rail-to-Rail o Double-Buffered Registers for Synchronous Updating o Power-On Reset Sets All Registers to Zero Features o +2.7V to +5.5V Single-Supply Operation MAX5100 Ordering Information PART MAX5100AEUP MAX5100BEUP TEMP.
