SLOS405A DECEMBER 2002– REVISED APRIL 2003
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)
