DAC Output
The AD9859 incorporates an integrated 10-bit current output
DAC. Unlike most DACs, this output is referenced to AVDD,
not AGND.
Two complementary outputs provide a combined full-scale
output current (IOUT). Differential outputs reduce the amount of
common-mode noise that might be present at the DAC output,
offering the advantage of an increased signal-to-noise ratio. The
full-scale current is controlled by an external resistor (RSET)
connected between the DAC_RSET pin and the DAC ground
(AGND_DAC). The full-scale current is proportional to the
resistor value as follows:

The maximum full-scale output current of the combined DAC
outputs is 15 mA, but limiting the output to 10 mA provides the
best spurious-free dynamic range (SFDR) performance. The DAC
output compliance range is AVDD + 0.5 V to AVDD – 0.5 V.
Voltages developed beyond this range cause excessive DAC
distortion and could potentially damage the DAC output
try. Proper attention should be paid to the load
keep the output voltage within this compliance
Serial I/O Port
The AD9859 serial port is a flexible, synchronous serial
communications port that allows easy interface to many industry-
standard microcontrollers and microprocessors. The serial I/O port
is compatible with most synchronous transfer formats, including
both the Motorola 6905/11 SPI and Intel 8051 SSR protocols.
The interface allows read/write access to all registers that configure
the AD9859. MSB first or LSB first transfer formats are supported.
The AD9859’s serial interface port can be configured as a single pin
I/O (SDIO), which allows a 2-wire interface or two unidirectional
pins for in/out (SDIO/SDO), which in turn enables a 3-wire
interface. Two optional pins, IOSYNC and CS

, enable greater
flexibility for system design in the AD9859.
