C-Load and ThinSOT are trademarks of Linear Technology Corporation.
The LT
6210/LT6211 are single/dual current feedback
amplifiers with externally programmable supply current
and bandwidth ranging from 10MHz at 300
A per ampli-
fier to 200MHz at 6mA per amplifier. They feature a low
distortion rail-to-rail output stage, 700V/
s slew rate and
a minimum output current drive of 75mA.
The LT6210/LT6211 operate on supplies as low as a single
3V and up to either 12V or
6V. The I
SET
pin allows for the
optimization of quiescent current for specific bandwidth,
distortion or slew rate requirements. Regardless of supply
voltage, the supply current is programmable from just
300
A to 6mA per amplifier with an external resistor or
current source.
The LT6210 is available in the low profile (1mm) 6-lead
SOT-23 package. The LT6211 is available in the 10-lead
MSOP and the 3mm x 3mm x 0.8mm DFN packages.
