Overview
Data Sheet FEATURES 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: −40°C to +105°C High Voltage, Quad-Channel 12-Bit Voltage Output DAC AD5504 GENERAL DESCRIPTION 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 SPI®-, QSPI™-, MICROWIRE™-, and DSP-interface standards and can handle clock speeds of up to 16.
667 MHz.
