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.
