The LT
6205/LT6206/LT6207 are low cost single/dual/
quad voltage feedback amplifiers that feature 100MHz
gain-bandwidth product, 450V/
s slew rate and 50mA
output current. These amplifiers have an input range that
includes ground and an output that swings within 60mV of
either supply rail, making them well suited for single
supply operation.
These amplifiers maintain their performance for supplies
from 2.7V to 12.6V and are specified at 3V, 5V and
5V.
The inputs can be driven beyond the supplies without
damage or phase reversal of the output. Isolation between
channels is high, over 90dB at 10MHz.
The LT6205 is available in the 5-pin SOT-23, and the
LT6206 is available in an 8-lead MSOP package with
standard op amp pin-outs. For compact layouts the quad
LT6207 is available in the 16-pin SSOP package. These
devices are specified over the commercial and industrial
temperature ranges.

OUT

Note 1: Absolute Maximum ratings are those values beyond which the life
of a device may be impaired.
Note 2: The inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 1.4V, the input current should be limited to less than
10mA.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum. This depends on the power supply voltage and
how many amplifiers are shorted.
Note 4: The LT6205C/LT6206C/LT6207C are guaranteed to meet specified
performance from 0
C to 70
C and 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 LT6205I/LT6206I/
LT6207I are guaranteed to meet specified performance from
40
C to 85
C.
Note 5: Matching parameters are the difference between the two amplifiers
A and D and between B and C of the LT6207; between the two amplifiers
of the LT6206.
Note 6: This parameter is not 100% tested.
Note 7: Output voltage swings are measured between the output and
power supply rails.
Note 8: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2
V
PEAK
.
Note 9: There are reverse biased ESD diodes on all inputs and outputs.
If these pins are forced beyond either supply, unlimited current will flow
through these diodes. If the current is transient in nature and limited to
less than 25mA, no damage to the device will occur.
