GENERAL DESCRIPTION
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 compatible
with SPI-, QSPI-, MICROWIRE-, and DSP-interface standards
and can handle clock speeds of up to 16.667 MHz.
