General Description
The MAX509/MAX510 are quad, serial-input, 8-bit voltage-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 reference input range includes both supply rails.
The MAX509 has four separate reference inputs, allowing each DACs 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 reference inputs, each shared by two DACs. The MAX510 is housed in space-saving 16-pin DIP and SO packages.
