• Description: (LT6233 - LT6235) Op Amp Family
• Manufacturer: Linear Technology

LT6233/LT6233-10/
LT6234/LT6235
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 LT6233C/LT6233I the LT6234C/LT6234I, and LT6235C/
LT6235I are guaranteed functional over the temperature range of –40 C
and 85 C.
Note 5: The LT6233C/LT6234C/LT6235C are guaranteed to meet specified
performance from 0 C to 70 C. The LT6233C/LT6234C/LT6235C 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 LT6233I/LT6234I/LT6235I 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 LT6235; between the two amplifiers
of the LT6234. CMRR and PSRR match are defined as follows: CMRR and
PSRR are measured in V/V on the matched amplifiers. The difference is
calculated between the matching sides in V/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:
Note 10: This parameter is not 100% tested.
