High Voltage, Quad Channel 12-Bit Voltage Output DAC

The AD5504 is a quad-channel, 12-bit, serial input, digital-to-analog converter with on-chip high voltage output amplifiers and an integrated precision reference. The DAC output voltage ranges are programmable via the range select pin (RSEL). If RSEL is held high, the DAC output ranges are 0 V to 30 V. If RSEL is held low, the DAC output ranges are 0 V to 60 V. The on-chip output amplifiers allow an output swing within the range of AGND + 0.5 V to VDD − 0.5 V.

The AD5504 has a high speed serial interface, which is com-patible with SPI®-, QSPI™-, MICROWIRE™-, and DSP-interface standards and can handle clock speeds of up to 16.667 MHz.
