MAX5258, MAX5259 +3V/+5V, Low-Power, 8-Bit Octal DACs With Rail-to-Rail Output Buffers

The MAX5258 MAX5259 are +3V/+5V single-supply, digital serial-input, voltage-output, 8-bit octal digital-to-analog converters (DACs). Internal precision Buffers swing Rail-to-Rail and the reference input range extends from ground to the positive supply. Both the +5V MAX5258 and the +3V MAX5259 feature a 10A (max) shutdown mode.
The serial Interface is double buffered: a 16-bit input Shift register is followed by eight 8-bit input Registers and eight 8-bit DAC Registers The 16-bit serial word consists of 2 "don't care" bits, 3 address bits, 3 control bits, and 8 data bits. Both the input and DAC Registers CAN be updated independently or simultaneously with a single software command. The asynchronous control input, active-low LDAC, provides simultaneous updating of all 8 DAC Registers
The Interface is compatible with SPI, QSPI (CPOL = CPHA = 0 or CPOL = CPHA = 1), and MICROWIRE. A buffered digital data output allows daisy-chaining of serial devices.
The MAX5258 MAX5259 are available in a 16-pin QSOP package.
