GENERAL DESCRIPTION
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.
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.
