MAX5150/MAX5151 19-1255 Rev 0 8/97 Low-Power, Dual, 13-Bit Voltage-Output DACs with Serial Interface General Description Features The MAX5150/MAX5151 low-power, serial, voltage-out- 13-Bit Dual DAC with Internal Gain of +2 put, dual 13-bit digital-to-analog converters (DACs) Rail-to-Rail Output Swing consume only 500A from a single +5V (MAX5150) or 16s Settling Time +3V (MAX5151) supply. These devices feature Rail-to- Single-Supply Operation: +5V (MAX5150) Rail output swing and are available in a space-saving 16-pin QSOP package. To maximize the dynamic +3V (MAX5151) range, the DAC output amplifiers are configured with an Low Quiescent Current: 500A (normal operation) internal gain of +2. 2A (shutdown mode) The 3-wire serial interface is SPI/QSPI and SPI/QSPI and Microwire Compatible Microwire compatible. Each DAC has a double- Available in Space-Saving 16-Pin QSOP Package buffered input organized as an input register followed Power-On Reset Clears Registers and DACs by a DAC register, which allows the input and DAC reg- to Zero isters to be updated independently or simultaneously with a 16-bit serial word. Additional features include Adjustable Output Offset programmable shutdown (2A), hardware-shutdown lockout, a separate reference voltage input for each Ordering Information DAC that accepts AC and DC signals, and an active- low clear input (CL) that resets all registers and DACs INL PART TEMP.
