DAC712
there is no change in DAC712 ACOM current, provided that
R
3
is a low-resistance ground plane or conductor. In this case
you may wish to connect DCOM to SYSTEM GROUND as
well.
GAIN AND OFFSET ADJUST
Connections Using Potentiometers
GAIN and OFFSET adjust pins provide for trim using
external potentiometers. 15-turn potentiometers provide suf-
ficient resolution. Range of adjustment of these trims is at
least
±
0.3% of Full Scale Range. Refer to Figure 6.
Using D/A Converters
The GAIN ADJUST and OFFSET ADJUST circuits of
DAC712 have been arranged so that these points may be
easily driven by external D/A converters. Refer to Figure 7.
12-bit D/A converters provide an OFFSET adjust resolution
and a GAIN adjust resolution of 30
μ
V to 50
μ
V per LSB
step.
Nominal values of GAIN and OFFSET occur when the D/A
converters outputs are at approximately half scale, +5V.
OUTPUT VOLTAGE RANGE CONNECTIONS
The DAC712 output amplifier is connected internally for the
±
10V bipolar (20V) output range. That is, the bipolar offset
resistor is connected to an internal reference voltage and the
20V range resistor is connected internally to V
OUT
. DAC712
cannot be connected by the user for unipolar operation.
DIGITAL INTERFACE
BUS INTERFACE
DAC712 has 16-bit double-buffered data bus interface with
control lines for easy interface to interface to a 16-bit bus.
The double-buffered feature permits update of several D/As
simultaneously.
