For the The 741 op amp, SVRR = 96 dB over the range 5V to 18V. 5V Open-Loop Op Amp Characteristics Table 12.11 Table Device LM741C LF351 OP-07 LH0003 AD549K Technology BJT BiFET BJT Hybrid BJT BiFET AOL(typ) 200 k 100 k 400 k 40 k 100 k Rin 2 M 1012 8 M 100 k 1013 || 1 pF Ro 50 30 60 50 ~100 SR 0.5 V/µ s 13 V/µ s 0.3 V/µ s 70 V/µ s 3 V/µ s CMRR 90 dB 100 dB 110 dB 90 dB 90 dB Sources Sources Dailey, Denton.
