High Voltage, Quad-Channel 12-Bit Voltage Output DAC Data Sheet AD5504 FEATURES GENERAL DESCRIPTION Quad-channel high voltage DAC The AD5504 is a quad-channel, 12-bit, serial input, digital-to- 12-bit resolution analog converter with on-chip high voltage output amplifiers Pin selectable 30 V or 60 V output range and an integrated precision reference. The DAC output voltage Integrated precision reference ranges are programmable via the range select pin (R SEL). If Low power serial interface with readback capability R SEL is held high, the DAC output ranges are 0 V to 30 V. If Integrated temperature sensor alarm function R SEL is held low, the DAC output ranges are 0 V to 60 V. The Power-on reset on-chip output amplifiers allow an output swing within the LDAC Simultaneous updating via range of AGND + 0.5 V to V 0.5 V. DD Wide operating temperature: 40C to +105C The AD5504 has a high speed serial interface, which is com- APPLICATIONS patible with SPI-, QSPI-, MICROWIRE-, and DSP-interface standards and can handle clock speeds of up to 16.667 MHz.
