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 10µA (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.
