SPECIFICATIONS: MAIN AMPLIFIER

VS+ = 5 V, VS– = 0 V, VOCM = 2.5 V, VICM = 2.5 V, VG– = 0 V, VG+ = 1 V (maximum gain), TA = 25°C, ac performance measured using the ac test

circuit shown in Figure 1 (unless otherwise noted). DC performance is measured using the dc test circuit shown in Figure 2 (unless otherwise

noted)
