8 / 13 page CN-0385 Circuit Note Rev. 0 | Page 8 of 13 Table 5 shows the gain error measured for each of the gain configurations for the circuit in Figure 1. The %FS error was found using the analysis methods described previously, and the actual gain in V/V was calculated by subtracting this error from the ideal gain. Table 5. Gain Error Measurements for all Gain Configurations Gain Gain Error (%FS) 0.4 0.02 0.8 0.02 1.6 0.03 3.2 0.02 Performance Results Without Channel Switching Figure 10, Figure 11, Figure 12, and Figure 13 show the fast Fourier transform (FFT) plots for a 10 kHz, full-scale, sine wave input on a single channel for gain configurations of 0.4, 0.8, 1.6, and 3.2, respectively. Table 6 shows the SNR and rms noise measured for each of the gain configurations. Table 6. SNR, Noise, and THD vs. Gain for 10 kHz Input Gain SNR (dB) RMS Noise (µV rms) THD (dB) 0.4 93.9 55.2 −99.2 0.8 92.8 62.6 −98.5 1.6 90.6 80.7 −97.0 3.2 88.0 108.9 −94.6 The input signal was supplied by an Audio Precision SYS-2700 series signal generator, with the board set in differential input mode. Figure 14 shows total harmonic distortion (THD) measurements vs. the frequency of the input signal for each gain configuration. Figure 10.
