DescripTion
The LT
®
6210/LT6211 are single/dual current feedback
amplifiers with externally programmable supply current
and bandwidth ranging from 10MHz at 300µA per ampli-
fier to 200MHz at 6mA per amplifier. They feature a low
distortion rail-to-rail output stage, 700V/µs 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
300µA to 6mA per amplifier with an external resistor or
current source.
The LT6210 is available in the low profile (1mm) 6-lead
TSOT-23 package. The LT6211 is available in the 10-lead
MSOP and the 3mm
