The AD5501 is a single-channel, 12-bit, serial input, digital-to-analog converter (DAC) with an on-chip high voltage output amplifier and an integrated precision reference. The DAC output voltage range is programmable via the range select pin (R_SEL). If R_SEL is held high, the DAC output range is 0 V to 30 V. If R_SEL is held low, the DAC output range is 0 V to 60 V. The on chip output amplifier allows an output swing within the range of AGND + 0.5 V to VDD - 0.5 V.
The AD5501 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.
