MAX509/MAX510 19-0155 Rev 3 12/10 Quad, Serial 8-Bit DACs with Rail-to-Rail Outputs General Description Features Single +5V or Dual 5V Supply Operation The MAX509/MAX510 are quad, serial-input, 8-bit volt- age-output digital-to-analog converters (DACs). They Output Buffer Amplifiers Swing Rail-to-Rail operate with a single +5V supply or dual 5V supplies. Reference Input Range Includes Both Supply Rails Internal, precision buffers swing rail-to-rail. The refer- Calibrated Offset, Gain, and Linearity (1LSB TUE) ence input range includes both supply rails. 10MHz Serial Interface, Compatible with SPI, QSPI The MAX509 has four separate reference inputs, allow- (CPOL = CPHA = 0) and MICROWIRE ing each DAC s full-scale range to be set independently. Double-Buffered Registers for Synchronous 20-pin DIP, SSOP, and SO packages are available. The Updating MAX510 is identical to the MAX509 except it has two ref- erence inputs, each shared by two DACs. The MAX510 Serial Data Output for Daisy-Chaining is housed in space-saving 16-pin DIP and SO packages. Power-On Reset Clears Serial Interface and Sets The serial interface is double-buffered: A 12-bit input All Registers to Zero shift register is followed by four 8-bit buffer registers and Ordering Information four 8-bit DAC registers. A 12-bit serial word is used to load data into each register. Both input and DAC regis- TUE PART TEMP RANGE PIN-PACKAGE ters can be updated independently or simultaneously (LSB) with single software commands.

Typical short-circuit current DD SS to AGND is 50mA. Do not bias AGND more than +1V above DGND, or more than 2.5V below DGND. 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.
