Datasheet Analog Devices AD5025BRUZ

Fully Accurate, 12-/14-/16-Bit, Dual, VOUT
nanoDAC SPI Interface, 4.5 V to 5.5 V in a TSSOP AD5025/AD5045/AD5065 Data Sheet ence buffer is provided on chip. The AD5025/AD5045/AD5065
incorporate a power-on reset circuit that ensures the DAC output
powers up zero scale or midscale and remains there until a valid
write takes place to the device. The AD5025/AD5045/AD5065
contain a power-down feature that reduces the current consumption of the device to typically 400 nA at 5 V and provides software
selectable output loads while in power-down mode. The parts are
put into power-down mode over the serial interface. Total unadjusted error for the parts is <2.5 mV. The parts exhibit very low
glitch on power-up. The outputs of all DACs can be updated
simultaneously using the LDAC function, with the added
functionality of user-selectable DAC channels to simultaneously
update. There is also an asynchronous CLR that clears all DACs
to a software-selectable code—0 V, midscale, or full scale. The
parts also feature a power-down lockout pin, PDL, which can be
used to prevent the DAC from entering power-down under any
circumstances over the serial interface. FEATURES
