High Voltage, Quad-Channel
12-Bit Voltage Output DAC
AD5504 Data Sheet
FEATURES GENERAL DESCRIPTION Quad-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
Simultaneous updating via LDAC
Wide operating temperature: -40В°C to +105В°C The AD5504 is a quad-channel, 12-bit, serial input, digital-toanalog 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 compatible with SPIВ®-, QSPIв„ў-, MICROWIREв„ў-, and DSP-interface
standards and can handle clock speeds of up to 16.667 MHz. APPLICATIONS
