ELECTRICAL CHARACTERISTICS
Note 1: Absolute maximum ratings are those values beyond which the life
of the device may be impaired.
Note 2: Inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 0.7V, the input current must be limited to less than
40mA.
Note 3: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.
Note 4: The LT6230C/LT6230I the LT6231C/LT6231I, and LT6232C/
LT6232I are guaranteed functional over the temperature range of –40°C
and 85°C.
Note 5: The LT6230C/LT6231C/LT6232C are guaranteed to meet specified
performance from 0°C to 70°C. The LT6230C/LT6231C/LT6232C are
designed, characterized and expected to meet specified performance from
– 40°C to 85°C, but are not tested or QA sampled at these temperatures.
The LT6230I/LT6231I/LT6232I are guaranteed to meet specified
performance from –40°C to 85°C.
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.
