The AD5062, a member of ADI’s nanoDAC family, is a low power, single 16-bit unbuffered voltage-out DAC that operates
from a single 2.7 V to 5.5 V supply. The part offers a relative accuracy specification of ±1 LSB, and operation is guaranteed monotonic with a ±1 LSB DNL specification. The part uses a
versatile 3-wire serial interface that operates at clock rates up to 30 MHz, and is compatible with standard SPI?, QSPI?, MICROWIRE?, and DSP interface standards. The reference for the AD5062 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 zero scale or mid-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
300 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 <0.8 mV.
