AD5501 Datasheet | Analog Devices

Features 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: - 40°C to +105°C 12-Bit, High Voltage DAC with SPI Interface AD5501 GENERAL DESCRIPTION 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. The AD5501 has a high speed serial interface, which is patible with SPI®-, QSPI™-, MICROWIRE™-, and DSP-interface standards and can handle clock speeds of up to 16.667 MHz.
