REV. A
CURRENT OUTPUT MODE
One or both channels of the ADl864 can be operated in current
output mode. IOUT can be used to directly drive an external
current-to-voltage (I-V) converter. The internal feedback
resistor, RF, can still be used in the feedback path of the external
I-V converter, thus assuring that RF tracks the DAC over time
and temperature.
Of course, the AD1864 can also be used in voltage output mode
utilizing the onboard I-V converter.
VOLTAGE OUTPUT MODES As shown in the ADl864
block diagram, each channel of the ADl864 is complete with an
I-V converter and a feedback resistor. These can be connected
externally to provide direct voltage output from one or both
AD1864 channels. Figure 7 shows these connections. IOUT is
connected to the summing junction, SJ. VOUT is connected to
the feedback resistor, RF. This implementation results in the

INPUT DATA
Data is transmitted to the AD1864 in a bit stream composed of
18-bit words with a serial, twos complement, MSB first format.
Data Left (DL) and Data Right (DR) are the serial inputs for
the left and right DACs, respectively. Similarly, Latch Left (LL)
and Latch Right (LR) update the left and right DACs. The
falling edges of LL and LR cause the last 18 bits clocked into
the Serial Registers to be shifted into the DACs, thereby
updating the DAC outputs. Left and Right channels share the
Clock (CLK) signal. Data is clocked into the input registers on
the rising edge of CLK.

transfer for the AD1864.

TIMING
Figure 10 illustrates the specific timing requirements that must
be met in order for the data transfer to be properly accomplished.
The input pins of the AD1864 are both TTL and 5 V CMOS
compatible.
The minimum clock rate of the AD1864 is at least 12.7 MHz.
This clock rate allows data transfer rates of 2
×, 4×, 8× and
16

of this data sheet contains additional guidelines for using the
AD1864.
