DESCRIPTION
The
LT
®
6274/LT6275
are single/dual low power, high
speed, very high slew rate operational amplifiers with
outstanding AC and DC performance. The circuit topology
is a voltage feedback amplifier with matched high imped-
ance inputs plus the enhanced slewing performance of a
current feedback amplifier. The high slew rate and single
stage design provide excellent settling characteristics that
make the circuit an ideal choice for data acquisition sys-
tems. Each output drives a 1k load to ±13.25V with ±15V
supplies and a 500Ω load to ±3.5V on ±5V supplies. The
LT6274/LT6275 are stable with any capacitive load mak-
ing them useful in buffer or cable driving applications.
The LT6274 single op amp is available in a 5-lead TSOT-23
package, and the LT6275 dual op amp is available in an
8-lead MSOP package. They operate with guaranteed
specifications over the –40°C to 85°C and –40°C to 125°C
temperature ranges.

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:
Differential inputs of ±10V are appropriate for transient operation
only, such as during slewing. Large, sustained differential inputs will
cause excessive power dissipation and may damage the part. See Input
Considerations in the Applications Information section of this data sheet
for more details.
Note 3:
The inputs are protected by ESD protection diodes to each power
supply. The Input current should be limited to less than 10mA.
Note 4:
A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.
Note 5:
The LT6274I/LT6275I are guaranteed functional over the
operating temperature range of –40°C to 85°C. The LT6274H/LT6275H
are guaranteed functional over the operating temperature range of
–40°C to 125°C.
Note 6:
The LT6274I/LT6275I are guaranteed to meet specified
performance from –40°C to 85°C. The LT6274H/LT6275H are guaranteed
to meet specified performance from –40°C to 125°C.
Note 7:
Input offset voltage is pulse tested and is exclusive of warm-up drift.
Note 8:
This parameter is not 100% tested.
Note 9:
Input voltage range is guaranteed by common mode rejection ratio
test.
Note 10:
Supply voltage range is guaranteed by power supply rejection
ratio test.
Note 11:
Slew rate is measured between 20% and 80% of output step with
±6V input (at A
V
= –2) and ±10V input (at A
V
= ±1) for ±15V supplies, and
between 35% and 65% of output step with ±1.75V input (at A
V
= –2) for
±5V supplies.
Note 12:
Current density limitations within the IC require the continuous
RMS current supplied by the output (sourcing or sinking) over the
operating lifetime of the part be limited to under 115mA (Absolute
Maximum). Proper heat sinking may be required to keep the junction
temperature below the absolute maximum rating.
