Description
AD5666
GENERAL DESCRIPTION
The AD5024/AD5044/AD5064 are low power, quad 12-/14-/
16-bit buffered voltage output nanoDAC® DACs that offer relative
accuracy specifications of 1 LSB INL with individual reference
pins and can operate from a single 4.5 V to 5.5 V supply. The
AD5024/AD5044/AD5064 parts also offer a differential accuracy
specification of ±1 LSB. The parts use a versatile 3-wire, low
power Schmitt trigger serial interface that operates at clock rates
up to 50 MHz and is compatible with standard SPI, QSPI™,
MICROWIRE™, and DSP interface standards. A reference buffer
is also provided on-chip. The AD5024/AD5044/AD5064 incor-
porate a power-on reset circuit that ensures the DAC output
powers up to zero scale or midscale and remains there until a
valid write takes place to the device. The AD5024/AD5044/
AD5064 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.
Total unadjusted error for the parts is <2 mV.
