MAX5150, MAX5151 Low-Power, Dual, 13-Bit Voltage-Output DACs With Serial Interface

The MAX5150 MAX5151 low-power, serial, voltage-output, dual 13-bit digital-to-analog converters (DACs) consume only 500A from a single +5V MAX5150 or +3V MAX5151 supply. These devices feature Rail-to-Rail output swing and are available in a space-saving 16-pin QSOP package. To maximize the dynamic range, the DAC output Amplifiers are configured with an internal gain of +2.
The 3-wire serial Interface is SPI"/QSPI" and MICROWIRE" compatible. Each DAC has a double-buffered input organized as an input Register followed by a DAC Register which allows the input and DAC Registers to be updated independentl 739 y or simultaneously with a 16-bit serial word. Additional features include programmable shutdown (2A), hardware-shutdown lockout, a separate reference voltage input for each DAC that accepts AC and DC signals, and an active-low clear input (CL) that resets all Registers and DACs to zero. These devices provide a programmable Logic pin for added functionality, and a serial-data output pin for daisy-chaining.
