PERFORMANCE CHARACTERISTICS
This section details the key specifications of the AD203SN that
exhibit a functional dependence on such variables as frequency,
power supply load, output voltage swing, bypass capacitance
and temperature. Table I summarizes the performance charac-
teristics that will be discussed in this section. For the sake of
completeness, a typical dynamic output response of the
AD203SN is included.
Gain Temperature Coefficient. Figure 1 presents the
AD203SN's gain temperature coefficient over the entire -55°C
to + 125°C temperature range.

Gain Nonlinearity. The maximum nonlinearity error of the
AD203SN, at a gain of 1 VIV, is specified as ±0.025% or
± 5 mV. The nonlinearity performance of the AD203SN is de-
pendent on the output voltage swing and this dependency is il-
lustrated in Figure 2. The horizontal axis represents the gain
error, expressed either in percent of peak-to-peak output span
(i.e., % of 20 V) on the left axis or in mV on the right axis. The
vertical axis indicates the magnitude of the output voltage
swing.
