DIGITAL INTERFACE
The DR-11800 has double-buffered input registers which allow
for easy implementation of an interface with 8-bit or 16-bit data
buses. The DR-11800 can also be set up for asynchronous data
inputs. If the LBE, HBE and LDC input pins are left open, the
internal pull-up circuitry will set these pins to a high state and the
information at the data inputs (B1-B16) will be continuously con-
verted to sin
θ and cosθ at the analog outputs. In applications
requiring less than 16-bit resolution, the unused pins can be left
open. The data bits (B1-B16) are internally pulled-down to apply
a logic 0 to unconnected data inputs.

ANALOG OUTPUT PHASING
The DR-11800 provides an output of 6.8V sin
θ and 6.8V cosθ
for either a 26 Vrms reference (use pin 26; RH26, and pin 22;
RL26) or 115 Vrms reference (use pin 21; RH115, and pin 27;
RL115). FIGURE 2 illustrates the input connection for a 26V or
115V reference. FIGURE 3 illustrates the output phasing.
