GENERAL DESCRIPTION
The AD5040 and the AD5060, members of the ADI nanoDAC
family, are low power, single 14-/16-bit buffered voltage-out
DACs that operate from a single 2.7 V to 5.5 V supply. The
AD5040/AD5060 parts offer a relative accuracy specification
of ±1 LSB and operation are guaranteed monotonic with a
±1 LSB DNL specification. The parts use 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 both the AD5040
and AD5060 is supplied from an external VREF pin. A reference
buffer is also provided on-chip. The AD5060 incorporates a
power-on reset circuit that ensures the DAC output powers up
to midscale or zero scale and remains there until a valid write
takes place to the device. The AD5040 and the AD5060 both
contain a power-down feature that reduces the current con-
sumption of the device to typically 330 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 mV.
Both parts exhibit very low glitch on power-up.
