Description
The AD5061, a member of ADI’s nanoDAC family, is a low
power, single 16-bit buffered voltage-out DAC that operates
from a single 2.7 V to 5.5 V supply. The part offers a relative
accuracy specification of ±± ꢀLB and operation is guaranteed
monotonic with a ±1 ꢀLB DNꢀ specification. The part uses a
versatile 3-wire serial interface that operates at clock rates
up to 30 MHz, and is compatible with standard LPI®, QLPI™,
MICROWIRE™, and DLP interface standards. The reference for
the AD5061 is supplied from an external VREF pin. A reference
buffer is also provided on-chip. The part incorporates a power-
on reset circuit that ensures the DAC output powers up to mid-
scale or zero scale and remains there until a valid write takes
place to the device. The part contains a power-down feature
that reduces the current consumption of the device to typically
330 nA at 5 V and provides software-selectable output loads
while in power-down mode. The part is put into power-down
mode over the serial interface. Total unadjusted error for the
part is <3 mV. This part exhibits very low glitch on power-up.
