GENERAL DESCRIPTION
The AD5062/AD5063, a member of the nanoDACTM family,
are single 16-bit unbuffered voltage out DACs that operate
from a single 2.7-5V supply. The AD5062 version is available
in a 8 ld Sot23. The AD5063 version is available with on board
resistors in a 10 ld uSOIC, making it easy to generate bipolar
signals on the output.
The parts utilize a versatile three-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 AD5062/AD5063 is supplied from an
external REF pin. A reference buffer is also provided on chip.
The part incorporates a power-on-reset circuit that ensures that
the DAC output powers up to zero volts/ 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 50nA 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 <1mV.
These parts also provide a very low glitch on power-up.
