12-Bit, High Voltage DAC
with SPI Interface
AD5501 Data Sheet
FEATURES GENERAL DESCRIPTION Single-channel high voltage DAC
12-bit resolution
Pin-selectable 30 V or 60 V output range
Integrated precision reference
Low power serial interface with readback capability
Integrated temperature sensor alarm function
Power-on reset
Wide operating temperature range: -40В°C to +105В°C The AD5501 is a single-channel, 12-bit, serial input, digital-toanalog 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. APPLICATIONS The AD5501 has a high speed serial interface, which is compatible
with SPIВ®-, QSPIв„ў-, MICROWIREв„ў-, and DSP-interface standards
and can handle clock speeds of up to 16.667 MHz. Programmable voltage sources
