POWERING THE AD215
The AD215 is powered by a bipolar
±15 V dc power supply
connected as shown in Figure 11. External bypass capacitors
should be provided in bused applications. Note that a small
signal-related current (50 mA/VOUT) will flow out of the OUT
LO pin (Pin 37). Therefore, the OUT LO terminals should be
bused together and referenced at a single “Analog Star Ground”
to the
±15 V dc supply common as illustrated Figure 11.

Power Supply Voltage Considerations
The rated performance of the AD215 remains unaffected for
power supply voltages in the
±14.5 V dc to ±16.5 V dc range.
Voltages below
±14.25 V dc may cause the AD215 to cease op-
erating properly.
Note: Power supply voltages greater than
±17.5 V dc may damage
the internal components and consequently should not be used.

Noninverting Configuration for Gain Greater Than Unity
Figure 13 shows how to achieve a gain greater than one while
continuing to preserve a very high input impedance. A recom-
mended PC board layout for multichannel applications is shown
in Figure 20b.

Figure 13. Noninverting Input Configuration for
Gain > 1 V/V
In this circuit, the gain equation is as follows:
VO = (1 + RF/RG) × VSIG
where:
VO
= Output Voltage (V)
VSIG = Input Signal Voltage (V)
RF
= Feedback Resistor Value (
)
RG
= Gain Resistor Value (
)
The values for resistors RF and RG are subject to the following
constraints:
The total impedance of the gain network should be less than
10 k
.
The current drawn in RF is less than 1 mA at
±10 V. Note that
for each mA drawn by the feedback resistor, the isolated
power supply drive capability decreases by 1 mA.
Amplifier gain is set by the feedback (RF) and gain resistor
(RG).
It is recommended that RF is bypassed with a 47 pF capacitor as
shown.
Note: The 2 k
input resistor (R
IN) in series with the input
signal source and the IN+ terminal in Figures 12 and 13 is rec-
ommended to limit the current at the input terminals of the to
5.0 mA when the AD215 is not powered.
