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/2

Note 10: This parameter is not 100% tested.
