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 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: The LTC6244C/LTC6244HVC 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 LTC6244I/LTC6244HVI,
are guaranteed to meet specifi ed performance from –40°C to 85°C. The
LTC6244H is guaranteed to meet specifi ed performance from –40°C to
125°C.
Note 4: ESD (Electrostatic Discharge) sensitive device. ESD protection
devices are used extensively internal to the LTC6244; 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 amplifi ers
of the LTC6244. CMRR and PSRR match are defi ned as follows: CMRR
and PSRR are measured in µV/V on the amplifi ers. The difference is
calculated between the sides in µV/V. The result is converted to dB.
Note 6: This parameter is not 100% tested.
Note 7: This specifi cation is limited by high speed automated test
capability. See Typical Characteristics curves for actual typical
performance.
Note 8: Current noise is calculated from the formula: i
n
= (2qI
B
)
1/2
where q = 1.6 × 10
–19
coulomb. The noise of source resistors up to
50G dominates the contribution of current noise. See also Typical
Characteristics curve Noise Current vs Frequency.
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
F
= 1k and R
G
=
500. V
IN
is ±1V and V
OUT
slew rate is measured between –1V and +1V.
On the LTC6244HV/LTC6245HV, V
IN
is ±2V and V
OUT
slew rate is measured
between –2V and +2V.
Note 12: Full-power bandwidth is calculated from the slew rate:
FPBW = SR/2πV
P
.
