GENERAL DESCRIPTION
Table 1. Related Devices
The AD5061, a member of the Analog Devices, Inc., 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.
Part No.
