Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe MAX5258/MAX5259 are +3V/+5V single-supply, digital serial-input, voltage-output, 8-bit octal digital-toanalog converters (DACs). Internal precision buffers swing Rail-to-Rail®, and the reference input range extends from ground to the positive supply. The +5V (MAX5258) and the +3V (MAX5259) feature a 10µA (max) shutdown mode.
The MAX5258 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 two "don't care" bits, three address bits, three control bits, and eight data bits. The input and DAC registers can both be updated independently or simultaneously with a single software command. The asynchronous control input (LDAC) provides simultaneous updating of all eight DAC registers.
The MAX5258 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.
