3 / 20 page Data Sheet AD5504 Rev. B | Page 3 of 20 The serial interface offers the user the capability of both writing to, and reading from, most of the internal registers. To reduce power consumption at power up, only the digital section of the AD5504 is powered up initially. This gives the user the ability to program the DAC registers to the required value while typically only consuming 30 μA of supply current. The AD5504 incor- porates 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 taken place. The analog section is powered up by issuing a power-up command via the SPI interface. The AD5504 provides software-selectable output loads while in the power-down mode. The AD5504 has an on-chip temperature sensor. When the temperature on the die exceeds 110°C, the ALARM pin (an active low CMOS output pin) flags an alarm and the AD5504 enters a temperature power-down mode disconnecting the output amplifier thus removing the short-circuit condition. The AD5504 remains in power-down mode until a software power-up command is executed. The AD5504 is available in a compact 16-lead TSSOP. The AD5504 is guaranteed to operate over the extended temperature range of −40°C to +105°C. Table 1. Related Device Part No. Description AD5501 High Voltage, 12-Bit Voltage Output DAC |
