MAX509ACAP+ [Analog Devices]

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 DAC's full-scale range to be set independently. The MAX510 is identical to the MAX509 except it has two reference inputs, each shared by two DACs. The serial interface is double-buffered and compatible with MICROWIRE, SPI, and QSPI. All digital inputs and outputs are TTL/CMOS compatible. A buffered data output provides for readback or daisy-chaining of serial devices.
