LTC6240/LTC6241/LTC6242
ELECTRICAL CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 6: This parameter is not 100% tested.
Note 7: Bias current at T = 25°C is 100% tested and guaranteed for the
A
LTC6240 in the S8 package. The LTC6240S5, LTC6241 and LTC6242 are
expected to achieve the same performance as the LTC6240S8. All parts are
guaranteed to meet specifications over temperature.

Note 2: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.
Note 8: Current noise is calculated from the formula: i = (2qI ) where

q = 1.6 × 10 coulomb. The noise of source resistors up to 50GΩ
dominates the contribution of current noise. See also Typical Performance
Characteristics curve Noise Current vs Frequency.
Note 3: The LTC6240C/LTC6240HVC/LTC6241C/LTC6241HVC, LTC6242C/
LTC6242HVC are guaranteed to meet specified performance from 0°C to
70°C. They 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 LTC6240I/LTC6240HVI, LTC6241I/LTC6241HVI,
LTC6242I/LTC6242HVI are guaranteed to meet specified performance
from –40°C to 85°C. All versions of the LTC6240H/LTC6241H/LTC6242H
are guaranteed to meet specified performance from –40°C to 125°C.
Note 4: ESD (Electrostatic Discharge) sensitive device. ESD protection
devices are used extensively internal to the LTC6240/LTC6241/LTC6242;
however, high electrostatic discharge can damage or degrade the device.
Use proper ESD handling precautions.
Note 5: Matching parameters are the difference between the two amplifiers
A and D and between B and C of the LTC6242; between the two amplifiers
of the LTC6241. 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 9: Output voltage swings are measured between the output and
power supply rails.
Note 10: Minimum supply voltage is guaranteed by the power supply
rejection ratio test.
Note 11: Slew rate is measured in a gain of –2 with R = 1k and R =
500Ω. On the LTC6240/LTC6241/LTC6242, V = 2.5V, V is 1V and

slew rate is measured between –1V and +1V. On the LTC6240HV/
LTC6241HV/LTC6242HV, V is 2V and V

between –2V and +2V.
Note 12: Full-power bandwidth is calculated from the slew rate:
FPBW = SR/πV
