GROUNDING RULES
The AD565A and AD566A bring out separate reference and
power grounds to allow optimum connections for low noise and
high-speed performance. These grounds should be tied together
at one point, usually the device power ground. The separate
ground returns are provided to minimize current flow in
low-level signal paths. In this way, logic return currents are not
summed into the same return path with analog signals.
CONNECTING THE AD565A FOR BUFFERED VOLTAGE
OUTPUT
The standard current-to-voltage conversion connections using
an operational amplifier are shown here with the preferred
trimming techniques. If a low offset operational amplifier
(AD510L, AD517L, AD741L, AD301AL, AD OP07) is used,
excellent performance can be obtained in many situations with-
out trimming (an op amp with less than 0.5 mV max offset
voltage should be used to keep offset errors below 1/2 LSB). If
a 50 Ω fixed resistor is substituted for the 100 Ω trimmer, uni-
polar zero will typically be within ± 1/2 LSB (plus op amp off-
set), and full-scale accuracy will be within 0.1% (0.25% max).
Substituting a 50 Ω resistor for the 100 Ω bipolar offset trimmer
will give a bipolar zero error typically within ± 2 LSB (0.05%).
The AD509 is recommended for buffered voltage-output appli-
cations which require a settling time to ± 1/2 LSB of one micro-
second. The feedback capacitor is shown with the optimum
value for each application; this capacitor is required to compen-
sate for the 25 picofarad DAC output capacitance.
