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 (R_SEL). If R_SEL is held high, the DAC output ranges are 0 V to 30 V. If R_SEL 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.
