12-Bit, High Voltage DAC with SPI Interface

AD5501

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 + V to VDD − V.

The AD5501 has a high speed serial interface, which is compatible with QSPI -, MICROWIRE -, and DSP-interface standards and can handle clock speeds of up to MHz.

Data Sheet

The serial interface offers the user the capability of both writing to, and reading from, most internal registers.

To reduce power consumption at power up, only the digital section of the AD5501 is powered up initially. This gives the user the ability to program the DAC registers to the required value while typically consuming only 30 uA of supply current. The AD5501 incorporates power-on reset circuitry that ensures the DAC registers power up in a known condition and remain there until a valid write to the device has occurred. The analog section is powered up by issuing a power-up command via the SPI interface. The AD5501 provides software-selectable output loads while in the power-down mode.

AD5501

The AD5501 has on-chip temperature sensor. If the temperature on the die exceeds 110°C, the ALARM pin an active low CMOS output pin flags an alarm and the AD5501 enters a temperature power-down mode that disconnects the output amplifier, thus removing the short-circuit condition. The AD5501 remains in power-down mode until a software power-up command is executed.

The AD5501 is available in a compact 16-lead TSSOP. The AD5501 is guaranteed to operate over the extended temperature range of −40°C to +105°C.
