*1 The differential output voltage (V
OUT+ − VOUT−) with respect to the differential input voltage (VIN+ − VIN−), where VIN+ =
−200 mV to 200 mV and V
IN− = 0 V) is measured under the circuit shown in Fig. 2 NL200, G Test Circuit. Upon
the resulting chart, the gain is defined as the slope of the optimum line obtained by using the method of least
squares.
*2 The differential output voltage (V
OUT+ − VOUT−) with respect to the differential input voltage (VIN+ − VIN−) is measured
under the circuit shown in Fig. 2 NL200, G Test Circuit. Upon the resulting chart, the optimum line is obtained by
using the method of least squares. Non-linearity is defined as the ratio (%) of the optimum line obtained by dividing
[Half of the peak to peak value of the (residual) deviation] by [full-scale differential output voltage].
For example, if the differential output voltage is 3.2 V, and the peak to peak value of the (residual) deviation is 22.4
mV, while the input V
IN+ is ±200 mV, the output non-linearity is obtained as follows:
NL200 = 22.4/(2 × 3 200) = 0.35%
*3 CMRR
IN is defined as the ratio of the differential signal gain (when the differential signal is applied between the
input pins) to the common-mode signal gain (when both input pins are connected and the signal is applied). This
value is indicated in dB.
