The MAX509/MAX510 are quad, serial-input, 8-bit volt-age-output digital-to-analog converters (DACs). They operate with a single +5V supply or dual ±5V supplies.Internal, precision buffers swing rail-to-rail. The refer-ence input range includes both supply rails.
The MAX509 has four separate reference inputs, allow-ing each DAC's full-scale range to be set independently. 20-pin DIP, SSOP, and SO packages are available. The MAX510 is identical to the MAX509 except it has two ref-erence inputs, each shared by two DACs. The MAX510 is housed in space-saving 16-pin DIP and SO packages.
The serial interface of MAX510 is double-buffered: A 12-bit input shift register is followed by four 8-bit buffer registers and four 8-bit DAC registers. A 12-bit serial word is used toload data into each register. Both input and DAC regis-ters can be updated independently or simultaneously with single software commands. Two additional asyn-chronous control pins provide simultaneous updating (LDAC) or clearing (CLR) of input and DAC registers.
TM
The interface of MAX510 is compatible with Microwire and SPI/QSPI TM. All digital inputs and outputs are TTL/CMOS compatible. A buffered data output provides for read-
back or daisy-chaining of serial devices.
