LT6231/LT6232
Electrical Characteristics
Note 6: Matching parameters are the difference between the two amplifiers
A and D and between B and C of the LT6232; between the two amplifiers
of the LT6231. CMRR and PSRR match are defined as follows: CMRR and
PSRR are measured in µV/V on the matched amplifiers. The difference is
calculated between the matching sides in µV/V. The result is converted to
dB.
Note 7: Minimum supply voltage is guaranteed by power supply rejection
ratio test.
Note 8: Output voltage swings are measured between the output and
power supply rails.
Note 9: Full-power bandwidth is calculated from the slew rate:
FPBW = SR/2πVP
Note 10: This parameter is not 100% tested.
