APPLICATIONS INFORMATION
BASIC CONNECTION
the AD623. The +VS and VS terminals are connected to the
power supply. The supply can be either bipolar (VS = ±2.5 V to
±6 V) or single supply (VS = 0 V, +VS = 3.0 V to 12 V). Power
supplies should be capacitively decoupled close to the power pins of
the device. For the best results, use surface-mount 0.1 μF ceramic
chip capacitors and 10 μF electrolytic tantalum capacitors.

Figure 43. Single-Supply Basic Connection
The input voltage, which can be either single-ended (tie either
IN or +IN to ground), or differential is amplified by the
programmed gain. The output signal appears as the voltage
difference between the OUTPUT pin and the externally applied
voltage on the REF input. For a ground-referenced output, REF
should be grounded.
GAIN SELECTION
The gain of the AD623 is resistor programmed by RG, or more
precisely, by whatever impedance appears between Pin 1 and
Pin 8. The AD623 is designed to offer accurate gains using 0.1%
to 1% tolerance resistors. Table 5 shows the required values of
RG for the various gains. Note that for G = 1, the RG terminals
are unconnected (RG = ∞). For any arbitrary gain, RG can be
calculated by
RG
= 100 kΩ/(G 1)
REFERENCE TERMINAL
The reference terminal potential defines the zero output voltage
and is especially useful when the load does not share a precise
ground with the rest of the system. It provides a direct means of
injecting a precise offset to the output. The reference terminal is
also useful when bipolar signals are being amplified because it
can be used to provide a virtual ground voltage. The voltage on
the reference terminal can be varied from VS to +VS.
