Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefi nitely.
Note 3: All versions of the LTC6241/LTC6242 are guaranteed functional
over the temperature range of –40°C and 85°C.
Note 4: The LTC6241C/LTC6241HVC, LTC6242C/LTC6242HVC are
guaranteed to meet specifi ed performance from 0°C to 70°C. They are
designed, characterized and expected to meet specifi ed performance from
–40°C to 85°C, but are not tested or QA sampled at these temperatures.
The LTC6241I/LTC6241HVI, LTC6242I/LTC6242HVI are guaranteed to meet
specifi ed performance from –40°C to 85°C.
Note 5: ESD (Electrostatic Discharge) sensitive device. ESD protection
devices are used extensively internal to the LTC6241/LTC6242; however,
high electrostatic discharge can damage or degrade the device. Use proper
ESD handling precautions.
Note 6: Matching parameters are the difference between the two amplifi ers
A and D and between B and C of the LTC6242; between the two amplifi ers
of the LTC6241. CMRR and PSRR match are defi ned as follows: CMRR
and PSRR are measured in µV/V on the matched amplifi ers. The difference

is calculated between the matching sides in µV/V. The result is converted
to dB.
Note 7: This parameter is not 100% tested.
Note 8: This specifi cation is limited by high speed automated test
capability. See Typical Characteristics curves for actual typical
performance.
Note 9: Current noise is calculated from the formula: i
where q = 1.6 × 10
50GΩ dominates the contribution of current noise. See also Typical
Characteristics curve Noise Current vs Frequency.
Note 10: Output voltage swings are measured between the output and
power supply rails.
Note 11: Minimum supply voltage is guaranteed by the power supply
rejection ratio test.
Note 12: Slew rate is measured in a gain of –2 with R
= 500Ω. On the LTC6241/LTC6242, V
